3 Installing FRUs

	WARNING! 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 you complete FRU installations.

The chassis and module views in the figures in this section are for illustration only.

 

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

 

Attaching an ESD wrist strap

The switch 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 "Grounding the switch."

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 (S7506X-G switch)

 

Installing cards

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

These cards are hot swappable.

 

IMPORTANT: ·     Before installing a card in the chassis, make sure the connectors on the card are not broken or blocked to avoid damaging the backplane. ·     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.

 

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 each unused slot. ·     Do not install a power module adapter and a 3 RU 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 module redundancy and supports dual grid inputs. The switch supports AC and DC power. For information about the power modules available for the switch, see H3C S7500X-G Switch Series Hardware Information and Specification.

For a switch that uses high-capacity power modules, for example, the PSR1400-12D1 power modules, you can use the following configurations for power supply when the system power consumption is small:

·     Power module adapters and PSR650-A/PSR650-D power modules (not recommended) when the switch consumes less than 650 W.

·     LSQM1PWRSPB (0231A5X0) 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, install the power module adapter in the chassis first, and then install power modules in the power module adapter.

Installing 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

 

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 power modules to be installed can satisfy the power 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.     Correctly orient the power module.

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.

Connecting the power cord

	WARNING! Before connecting the power cord to a power module, make sure the power module is switched off.

 

	CAUTION: Typically 10A power strips are available in the equipment room but the PSR1200-A, PSR1400-A, and PSR2800-ACV power modules use 16A power cords. You must prepare a 16A power strip and make sure the AC power supply system can provide enough power. For the power cords used in different countries or regions, see H3C S7500X-G Switch Series Hardware Information and Specifications.

(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 an SFP+/SFP/QSFP+/QSFP28 module

	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.

 

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 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. Make sure the top and bottom tabs on the transceiver module are seated securely in the slot.

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."

Figure 3-14 Installing an SFP+ module

 

Connecting a network cable

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 copper cable must be a minimum of 15 times the copper cable diameter. ·     The bend radius of a fiber cable must be a minimum of 20 times the fiber 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 or QSFP+ fiber cable—Connects two QSFP+ ports over a short distance.

·     QSFP28 fiber cable—Connects two QSFP28 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 3-15, 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.
