4 Installing FRUs

As a best practice, connect power cords after installing all required FRUs. To ensure good ventilation, install filler panels in unused slots.

Long-time exposure to strong air flow might cause discomfort. To avoid this hazard, do not stand close to the air outlet vents while the switch is operating. If you must be next to the switch on the air outlet vent side for an extended period, avoid the air flow or take other protective measures.

 

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

 

Attaching an ESD wrist strap

The switch is provided with an ESD wrist strap. To minimize ESD damage to electronic components, wear the ESD wrist strap and make sure it is reliably grounded before you install FRUs.

To attach an ESD wrist strap:

1.     Make sure the switch is reliably grounded. For information about how to ground your switch, see "Grounding the switch."

2.     Put on the wrist strap.

3.     Tighten the wrist strap to make sure it makes good skin contact.

Make sure the resistance reading between your body and the ground is between 1 and 10 megohms.

4.     As shown in Figure4-1, insert the ESD wrist strap into the ESD jack on the chassis.

Figure4-1 Attaching an ESD wrist strap (S10506X-G)

 

Installing modules

	IMPORTANT: Before installing a module in the chassis, make sure the connectors on the module are not broken or blocked.

 

Unless otherwise stated, MPUs, service modules, and switch fabric modules are collectively referred to as "modules" in this document. The modules are hot swappable.

For the modules available for the switch, see "FRUs and compatibility matrixes" in H3C S10500X-G Switch Series Hardware Information and Specifications.

Installing MPUs

CAUTION: ·     If you are not to install an MPU in an MPU slot, keep the filler panel in the slot to prevent dust and ensure good ventilation in the switch. ·     When you install an MPU, avoid damaging the connectors on the MPU. ·     To prevent a filler panel from being drawn into the chassis when fan speed is high, use both hands to grasp the filler panel by its two sides during filler panel installation and removal on an operating switch.

 

	IMPORTANT: Captive screws are required to install an MPU or service module on the switch. As a best practice, use a torque of 5.5 kgf-cm (0.54 Nm) to fasten the captive screws.

 

You can install one MPU, or two MPUs for redundancy on the switch. If you are to install one MPU, install it in either of the MPU slots.

The installation procedure is similar for MPUs and service modules. For how to install an MPU or service module, see "Installing service modules."

Installing service modules

CAUTION: ·     To prevent a filler panel from being drawn into the chassis when fan speed is high, use both hands to grasp the filler panel by its two sides during filler panel installation and removal on an operating switch. ·     Keep filler panels installed on unused service module slots.

 

To install a service module:

1.     As shown by callout 1 in Figure4-2, open the ejector levers on the service module.

2.     As shown by callout 2 in Figure4-2, orient the service module with the lettering on it upward. Holding the module by the front panel with one hand and supporting its bottom with the other, insert the service module steadily into the target slot along the guide rails.

Keep the service module parallel to the slot to avoid touching other components in the chassis.

3.     Push the service module until the brakes on the ejector levers engage the edges of the slot.

4.     Continue to push the service module by its middle part on the front panel until you cannot push it.

5.     As shown by callout 3 in Figure4-2, close the ejector levers until they come in close contact with the front panel of the service module.

6.     As shown by callout 4 in Figure4-2, use a screwdriver to fasten the captive screws on the service module.

Figure4-2 Installing a service module (S10506X-G)

 

Installing a service module filler panel

CAUTION: Before installing a filler panel, differentiate between an MPU filler panel and a service module filler panel. A service module filler panel has air outlet vents on its front panel, but an MPU filler panel does not.

 

Figure4-3 An MPU filler panel and a service module filler panel (S10512X-G)

 

To install a service module filler panel:

Installing switch fabric modules

CAUTION: ·     When you install a switch fabric module, avoid damaging the connectors on it. ·     Each switch fabric module for an S10508X-G or S10512X-G switch has a protection box at the connectors side. Before you install a switch fabric module, first remove the metal protection box. ·     Install switch fabric modules or switch fabric module slot filler panels before you install the fan tray. ·     Install filler panels in the empty switch fabric module slots to prevent dust and ensure good ventilation in the switch. ·     To replace or install a switch fabric module for an operating switch, first remove the fan tray that covers the slot of the switch fabric module. Install the fan tray immediately after the replacement or installation. After the fan tray starts operating, you can replace or install switch fabric modules whose slots are covered by the other fan tray. ·     The smart speed adjustment feature increases the fan speed when only one fan tray is operating. Take noise protection measures such as wearing an earmuff or earplug. In addition, make good preparation before hot swapping a switch fabric module to minimize the operation time. ·     Install a minimum of two switch fabric modules on the switch according to the switch fabric module slot priority description at the chassis rear strictly.

 

An S10506X-G switch has four vertically-oriented switch fabric module slots at the chassis rear.

An S10508X-G and an S10512X-G switch each have six vertically-oriented switch fabric module slots at the chassis rear.

To install a switch fabric module:

1.     Place the switch fabric module on the workbench horizontally, and then remove the protection box (if any) at the connectors side as shown in Figure4-9.

Installing transceiver modules and optical fibers

	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.

 

CAUTION: ·     Be careful not to touch the golden plating on a transceiver module during the installation process. ·     To avoid network cable damage and signal loss, do not strain or tangle a network cable. ·     Make sure the transceiver module is aligned correctly with the target port before pushing it into the port. ·     Make sure the two module ends of a network cable are compatible with the ports into which they will be inserted.

 

Installing an SFP/SFP+/SFP28/QSFP+/QSFP28/QSFP-DD transceiver module

	CAUTION: ·     Read the following instructions before you install a transceiver module. Failure to follow these instructions might cause damage to the transceiver module. ·     Do not remove the dust plug from the transceiver module if you are not to connect an optical fiber to the module. ·     Before installing a transceiver module, remove the optical fiber (if any) from it.

 

Two types of QSFP+ transceiver modules are available. One type uses a metal pull latch and the other 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 SFP, SFP+, SFP28, QSFP+, QSFP28, and QSFP-DD transceiver modules. The following procedure uses an SFP+ transceiver module as an example.

To install an SFP+ transceiver module:

1.     Wear an ESD wrist strap. Make sure the wrist strap 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+ transceiver module. It comes with the bail latch catching the knob on the top of the transceiver module.

4.     Hold the transceiver module by its two sides and align the module with the fiber port. Gently push the transceiver module into the port until it is firmly seated in the fiber port, as shown in Figure4-21.

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 the switch to the network through an optical fiber."

Figure4-21 Installing an SFP+ transceiver module

 

Connecting a network cable

CAUTION: ·     The bend radius of a DAC cable must be a minimum of 15 times the cable diameter. ·     The bend radius of an AOC cable must be a minimum of 20 times the cable diameter.

 

The network cables are hot swappable.

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

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

·     SFP28 DAC cable—Connects two SFP28 ports over a short distance.

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

·     QSFP28 DAC or QSFP28 AOC 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.

·     QSFP28 to SFP28 DAC cable—Connects one QSFP28 port to four SFP28 ports over a short distance.

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

The connection procedure is similar for these cables. The following connection procedure uses the SFP+ DAC cable as an example.

To connect an SFP+ DAC cable:

1.     Wear an ESD wrist strap. Make sure the wrist strap 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 Figure4-22, 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.
