3 Installing FRUs

	CAUTION: Do not install the switch, modules, and cables when the switch has power.

 

There is no required order for installing FRUs. As a best practice, connect power cords after completing installing all required FRUs. Figures for the chassis and FRUs are for illustration only.

 

	TIP: Keep the chassis and the component packages for future use.

 

Attaching an ESD wrist strap

The S7500E series provides an ESD wrist strap. To minimize ESD damage to electronic components, wear an ESD wrist strap and ensure that it is reliably grounded when installing modules.

To use an ESD wrist strap:

1.        Make sure the switch is reliably grounded. For how to ground your switch, see "Connecting the grounding cable."

2.        Wear the wrist strap.

3.        Tighten the wrist strap to keep good skin contact. Make sure the resistance reading between your body and the ground is between 1 and 10 megohms.

4.        Insert the ESD wrist strap into the ESD socket on the switch chassis, or attach it to the grounding screw of the chassis with an alligator clip.

Figure 3-1 Attaching an ESD wrist strap (on an S7503E)

 

Installing cards

	CAUTION: To avoid damaging the backplane, make sure the connectors on the card are not broken or blocked before installing a card in the chassis.

 

	IMPORTANT: ·      To ensure good ventilation, install a filler panel in an empty slot. ·      Before you install a card that has a protection box, remove the protection box from the card as follows: a.    Loosen the captive screws that secure the card to the protection box. b.   Pull the ejector levers of the card outwards. c.    Pull the card out of the protection box.

 

The installation procedures for MPUs and service modules are the same. Unless otherwise stated, MPUs and service modules are collectively referred to as "cards" in this document.

These cards are hot swappable.

To install a card:

1.        Wear an ESD wrist strap, and make sure it has good skin contact and is reliably grounded. For more information, see "Attaching an ESD wrist strap."

2.        Remove the filler panel (if any) from the slot to be used. Keep the filler panel secure for future use.

3.        Rotate out the ejector levers on the card.

4.        Hold the card by the front panel with one hand and support the card bottom with the other (do not touch its circuit). Slide the card steadily into the slot along the guide rails until you cannot push the card further.

5.        Rotate in the ejector levers on the card.

6.        Fasten the captive screws on the card.

Figure 3-2 Installing a card

 

Installing the power supply system

CAUTION: ·      In case of dual grid inputs, make sure the amplitude, phase, and frequency of the input voltage of the two grids are the same. ·      Provide a circuit breaker for each power module. ·      For good ventilation of the switch, make sure a filler panel is installed in an unused slot. ·      Do not install a power module adapter and a 3RU power module on the same switch. Make sure the power configurations are the same on the two power module slots. To use power module adapters, make sure the two power module slots have the same power module adapter and power module configurations.

 

The switch uses 1+1 power redundancy and supports dual grid inputs. You can supply either AC or DC power for the switch. For information about the power modules available for the switch, see "Power modules."

For a switch that uses the PSR1400 or PSR2800 power modules, when the system power consumption is smaller than the power module capacity, you can use the following power configurations:

·          PSR650C-12A or PSR650C-12D power modules, or LSQM1PWRSPA/LSQM1PWRSPB power module adapters and PSR650-A/PSR650-D power modules (not recommended) when the switch consumes less than 650 W and does not use PoE.

·          LSQM1PWRSPB power module adapters and PSR650-A/PSR650-D/PSR1200-A/PSR1200-D power modules if you are to install more than two power modules in the switch.

To use a power module adapter, first install the power module adapter in the chassis, and then install power modules in the power module adapter.

Installing a power module adapter

	CAUTION: Do not install power module adapters of different models on the same switch.

 

To install a power module adapter:

1.        Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. For more information, see "Attaching an ESD wrist strap."

2.        Unpack the power module adapter.

3.        Holding the adapter handle with one hand and supporting the adapter bottom with the other, slide the adapter all the way into the chassis along the guide rails. Make sure the adapter is firmly seated in the chassis and has good contact with the backplane connectors.

To avoid damaging the power module adapter and the backplane connectors, remove the adapter, realign it with the chassis, and insert it again in case of misalignment.

4.        Use a Phillips screwdriver to fasten the captive screws on the adapter to secure the adapter in the chassis.

If you cannot fasten the captive screws tightly, check the adapter installation.

Figure 3-3 Installing a power module adapter (LSQM1PWRSPB)

 

Installing a power module

CAUTION: ·      Before installing a power module, make sure the switch on the power module is in the OFF position. ·      Do not install power modules of different models on the same switch. ·      Make sure the outputs of the power modules to be installed can satisfy the requirements of the switch. ·      To avoid damaging a power module, move the power module by supporting its bottom rather than holding its handle.

 

To install a power module:

1.        Wear an ESD wrist strap and make sure it has good skin contact and is reliably grounded. For more information, see "Attaching an ESD wrist strap."

2.        Remove the filler panel (if any) from the target slot.

Keep the filler panel secure for future use.

3.        Unpack the power module, and verify that the power module model is correct.

4.        Orient the power module correctly.

5.        Grasping the handle of the module with one hand and supporting the module bottom with the other, align the power module with the slot. Push the power module along the guide rails into the slot. Make sure the power module has a good contact with the backplane.

To avoid damaging the power module and the backplane connectors, remove the power module, realign it with the slot, and insert it again in case of misalignment.

6.        Use a Phillips screwdriver to fasten the captive screws on the power module to secure the power module in the chassis.

If the captive screws cannot be fastened tightly, do not fasten them forcibly. Check the power module installation.

(Optional) Setting up a PoE system

	CAUTION: If you do not use the PoE feature, verify that the PoE power switch on the power module is off.

 

Requirements

Power over Ethernet (PoE) enables a power sourcing equipment (PSE) to supply power to powered devices (PDs) through power interfaces (PIs) over twisted pair cables. Commonly used PDs include IP telephones, APs, and web cameras.

The following PoE types are available:

·          Type 1—Power delivered by a single port: 0 to 15.4 W; voltage range: 44 V to 57 V; maximum current: 350 mA. This PoE type provides power to classes 0 to 3 PDs.

·          Type 2—Power delivered by a single port: 0 to 30 W, voltage range: 50 V to 57 V, maximum current: 600 mA. This PoE type provides power to classes 0 to 4 PDs.

To set up a PoE system, the following components are required:

·          A switch that supports PoE.

·          PSEs.

·          An external PoE power supply.

·          PoE power modules.

A switch that supports PoE

The S7502E, S7503E, S7503E-S, S7506E, S7506E-MF, S7506E-V, or S7510E switch.

PSEs

All cards require a PoE dual in-line memory module (DIMM) to provide the PoE function, except the LSQ3GV48SC0 (LSQM3GV48SC0), LSQ1GV48SD0 (LSQM1GV48SD0), LSQM4GV48SA0, and LSQM4GV48SC0. PoE DIMMs include the following types:

·          24-port PoE DIMM LSQM1POEDIMMS0.

·          PoE master/subordinate DIMM LSBM1POEDIMMH.

For the compatibility between the two types of DIMMs and cards, see Table 3-2. For the installation of a PoE DIMM, see "Installing a PoE DIMM."

Table 3-2 Cards supporting PoE

Card model	PI quantity	DIMM	PoE type
LSQ1GV48SD0	48	Not required	·         Type 1 ·         Type 2
LSQ3GV48SC0	48	Not required	·         Type 1 ·         Type 2
LSQM4GV48SA0	48	Not required	·         Type 1 ·         Type 2
LSQM4GV48SC0	48	Not required	·         Type 1 ·         Type 2
LSQ1CGV24PSC0	24	LSQM1POEDIMMS0	Type 1
LSQ1GV24PSC0	24	LSQM1POEDIMMS0	Type 1
LSQ1GV24PSA0	24	LSQM1POEDIMMS0	Type 1
LSQ1FV48SA0	48	LSBM1POEDIMMH	Type 1
LSQ1GV48SA0	48	LSBM1POEDIMMH	Type 1
LSQ1GV48SC0	48	LSBM1POEDIMMH	Type 1
LSQ1GV40PSC0	40	LSBM1POEDIMMH	Type 1

 

	NOTE: ·      The model of a card is LSQM-prefixed on the card package and LSQ-prefixed on the card panel. For example, LSQ1GV48SD0 and LSQM1GV48SD0 identify the same card. ·      Make sure the total PoE power required by all PDs connected to a PSE is not greater than the maximum PSE power. For more information about the maximum PSE power, see "Total power consumption."

 

An external PoE power supply

An external PoE power supply is required only for the S7502E and S7503E-S switches because the two models use non-PoE power modules (PSR650-A/PSR650-D/PSR320-A/PSR320-D). The external PoE power supply must meet the following requirements:

·          Output voltage—–46 to –57 VDC for type 1 PoE mode and –52 to –57 VDC for type 2 PoE mode.

·          Maximum output current—40 A.

For how to connect an external PoE power supply, see "Connecting an external PoE power supply."

PoE power modules

PoE power modules are required only for the S7503E, S7506E, S7506E-MF, S7506E-V, and S7510E.

Table 3-3 PoE power modules

Power module	Max. output power	Power cords provided	Power cord connection
PSR1400-D	6720 W	No	Connecting the PSR1400-D/PSR1400-12D1/PSR2500-12D power module
PSR2800-ACV	·         1150 W (110 V) ·         1400 W (220 V)	Yes	Connecting the PSR2800-ACV power module
PSR6000-ACV	·         One-line PoE input: ¡  1200 W (110 V) ¡  1800 W (220 V) ·         Two-line PoE input: ¡  2400 W (110 V) ¡  3600 W (220 V) ·         Three-line PoE input: ¡  3600 W (110 V) ¡  5300 W (220 V)	Yes	Connecting the PSR6000-ACV

 

NOTE: ·      When the switch uses a PSR1400-D to supply PoE power, you can monitor the operating status of the external power supply through the PoE power monitoring port. The PoE power monitoring port is an RS-485 compliant port. You can select an RS-485 compliant connection method according to the monitoring port type. When you use a 48 VDC power source, you do not need to monitor the operating status of the external power supply. ·      When the switch uses a PSR6000-ACV to supply PoE power, make sure the input voltage for the system power input, PoE 1, PoE 2, and PoE 3 is the same. It can be either 110 VAC or 220 VAC.

 

Installing a PoE DIMM

	CAUTION: ·      Avoid touching the components on the PoE DIMM and PCB during installation and removal of a PoE DIMM. ·      If no PoE DIMM is in place or the module is not fully seated, the interface card cannot supply power, though other functions work well.

 

The PoE DIMM slot is a reverse insertion prevention slot to help you identify the direction for installing a PoE DIMM.

Installing the LSQM1POEDIMMS0

1.        Wear an ESD wrist strap and make sure it has a good skin contact and is reliably grounded. For more information, see "Attaching an ESD wrist strap."

2.        Make sure the card is sturdy. Then find the PoE DIMM slot (there is a master mark on the PCB under the slot) on the PCB.

3.        Pull the white clips on the two sides of the PoE DIMM slot outward, as shown by callout 1 in Figure 3-18.

4.        Unpack the PoE DIMM, and align the golden plating of the PoE DIMM with the groove on the slot.

If you select an MPU that supports the CF card, you can install a CF card as needed.

To install a CF card:

1.        Use a hard object to push the CF card eject button all the way into the slot, and make sure the button does not project from the panel.

2.        Push the CF card all the way into the CF card slot so that it does not project. At the same time, the eject button projects.

(Optional) Installing transceiver modules and network cables

	WARNING! Disconnected optical fibers or transceiver modules might emit invisible laser light. Do not stare into beams or view directly with optical instruments when the switch is operating.

 

Installing transceiver modules

	CAUTION: To avoid transceiver module or port damage, read this guide carefully before installing a transceiver module.

 

CAUTION: ·      Be careful not to touch the golden plating on a transceiver module during the installation process. ·      Before installing a transceiver module, remove the optical fibers, if any, from it. ·      Make sure the transceiver module is aligned correctly with the target port before pushing it into the port. ·      Do not remove the dust plugs from a transceiver module until you are ready to connect optical fibers to it.

 

Installing an XFP/SFP+/SFP/QSFP+/QSFP28 module

Two types of QSFP+ transceiver modules are available. One type uses a metal pull latch and the other type uses a plastic pull latch. The installation procedure is the same for the two types of QSFP+ transceiver modules.

The installation procedure is similar for the XFP, SFP+, SFP, QSFP+, and QSFP28 transceiver modules. The following procedure installs an SFP+ transceiver module.

To install an SFP+ transceiver module:

1.        Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. For more information, see "Attaching an ESD wrist strap."

2.        Remove the dust plug from the target fiber port.

3.        Unpack the SFP+ module. It comes with the bail latch catching the knob on the top of the transceiver module.

4.        Grasp the transceiver module between your thumb and index finger. Align it with the fiber port and push it gently into the port until it snaps into place.

Transceiver modules and fiber ports have disorientation rejection designs. If you cannot insert a transceiver module easily into a port, the orientation might be wrong. Remove and reorient the transceiver module.

In case of limited space, you can gently push against the front face of the transceiver module instead of the two sides.

5.        Connect optical fibers to the transceiver module. For the connection procedure, see "Connecting your switch to the network through optical fibers."

Installing a CFP module

1.        Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. For more information, see "Attaching an ESD wrist strap."

2.        Remove the dust plug from the target fiber port.

3.        Unpack the CFP module.

4.        Correctly orient the transceiver module and align it with the fiber port. Push it gently into the port until you feel it snaps into place. See Figure 3-25.

Transceiver modules and fiber ports have disorientation rejection designs. If you cannot insert a transceiver module easily into a port, the orientation might be wrong. Remove and reorient the transceiver module.

5.        Fasten the captive screws on the transceiver module to secure the module in place.

6.        Connect optical fibers to the transceiver module. For the connection procedure, see "Connecting your switch to the network through optical fibers."

Connecting network cables

CAUTION: When you connect a network cable, follow these restrictions and guidelines: ·      Make sure the two modular ends of a network cable are compatible with the ports into which they will be inserted. ·      Do not touch the golden plating on the two modular ends of a network cable. ·      To avoid network cable damage and signal loss, do not strain or tangle a network cable. ·      Before inserting a modular end of a network cable into a port, make sure the module aligns with the port correctly. ·      The bend radius of a network cable must be a minimum of 15 times the cable diameter.

 

To connect ports over a short distance, use network cables as follows:

·          SFP+ DAC cable—Connects two SFP+ ports over a short distance.

·          QSFP+ DAC cable—Connects two QSFP+ ports over a short distance.

·          QSFP+ to SFP+ DAC cable—Connects one QSFP+ port to four SFP+ ports over a short distance.

The network cables are hot swappable. The connection procedure is similar for these cables. The following procedure connects an SFP+ DAC cable.

To connect an SFP+ DAC cable:

1.        Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. For more information, see "Attaching an ESD wrist strap."

2.        Remove the dust plug from the target fiber port.

3.        Unpack the cable.

4.        As shown in Figure 3-26, align the module end of the cable with the fiber port and push it gently into the port until you feel it snaps into place.

Transceiver modules and fiber ports have disorientation rejection structures. If you cannot insert a transceiver module easily into a port, remove and reorient the transceiver module.
