Replacing removable components

CAUTION: ·     To avoid device damage or bodily injury, strictly follow the procedures provided in this chapter for component replacement. ·     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.

 

The gateway uses a modular architecture. You can replace the removable components on it.

Replacing a module

	CAUTION: ·     If you are not to install a new module in a slot after removing the old one, install a filler panel in the slot for adequate heat dissipation and dust prevention. ·     Before removing a module, first remove the cables from it.

 

Replacing a SEM

CAUTION: When two SEMs are installed on the gateway, you can hot swap the SEM in standby mode directly. If only one SEM is installed on the gateway, you cannot hot swap the SEM. To replace the only SEM on the gateway, you must power off the gateway first.

 

Replacing a SEM for an M9000-AI-E8 gateway

1.     Prepare an antistatic mat for placing the removed supervisor engine module (SEM).

2.     Wear an ESD wrist strap, and make sure it makes good skin contact and is reliably grounded.

3.     Use a Phillips screwdriver to loosen the captive screw on the left of the module.

4.     Pivot up the handle of the module and then pull the module slowly out of the slot.

5.     Place the removed module on the antistatic mat.

6.     Install a new SEM. For the installation procedure, see "Installing the gateway."

Replacing an interface switch module or AI security engine module

The replacement procedure is the same for the interface switch modules and AI security engine modules. This procedure replaces an interface switch module.

1.     Prepare an antistatic mat for placing the removed interface switch module.

2.     Wear an ESD wrist strap, and make sure it makes good skin contact and is reliably grounded.

3.     Pivot down the ejector levers of the interface switch module.

4.     Use a Phillips screwdriver to loosen the captive screws on the module.

5.     Open the two ejector levers of the module simultaneously to disengage the module from the backplane. Then pull the module slowly out of the slot.

6.     Place the removed module on the antistatic mat.

7.     Install a new interface switch module. For the installation procedure, see "Installing the gateway."

Replacing an interface module or service module

	CAUTION: You cannot hot swap interface modules or service modules on the gateway.

 

The replacement procedure is the same for service modules and interface modules. This procedure replaces an interface module.

1.     Prepare an antistatic mat for placing the removed interface module.

2.     Wear an ESD wrist strap, and make sure it makes good skin contact and is reliably grounded.

3.     Remove the interface switch module where the interface module resides. For the removal procedure, see "Replacing an interface switch module or AI security engine module."

4.     Press the release latch to release the ejector lever.

5.     Pull the interface module slowly out of the slot.

6.     Place the removed interface module on the antistatic mat.

7.     Install a new interface module. For the installation procedure, see "Installing the gateway."

Replacing a transceiver module

	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 gateway is operating.

 

	CAUTION: ·     Make sure the transceiver modules at the two ends of an optical fiber are the same model. ·     If you are no to install a transceiver module in a fiber port, insert a dust plug into the port. ·     Do not touch the golden plating on a transceiver module.

 

To replace a transceiver module

1.     Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.

2.     Remove the optical fiber from the transceiver module.

¡     To remove the optical fibers with an LC connector, press the clips on the connector to pull the LC connector out of the port, as shown in Figure 7.

¡     To remove the optical fiber with an MPO connector, hold the front end of the MPO connector to pull the connector out of the port, as shown in Figure 8.

3.     Pull down the bail latch on the module to the horizontal position (skip this step for transceiver modules with a plastic bail latch). Hold the bail latch to pull the module horizontally and slowly out of the port.

If the interface module is densely populated with transceiver modules, use tweezers to pull the module out.

4.     Insert dust plugs into the transceiver module and put the module into a packaging bag.

5.     Install a new transceiver module in the port. For the installation procedure, see "Installing the gateway."

Replacing a fan tray

WARNING! ·     Ensure electricity safety when you hot swap a fan tray. ·     To avoid bodily injury, do not touch the spinning fans when you replace the fan tray. ·     When you hot swap a fan tray, the fan rotation speed of the remaining fan trays automatically increases and the fan trays make louder noise. Take protection measures such as wearing an earmuff or earplug. In addition, make good preparations before the hot swapping to minimize the operation time.

 

CAUTION: ·     When a fan tray fails, replace the faulty fan tray immediately. ·     To prevent dust from entering the gateway, keep the old fan tray installed in the chassis until a new fan tray is ready to be installed. ·     Before hot swapping a fan tray, make sure the remaining fan trays can provide sufficient cooling for the router. ·     If multiple fan trays fail, do not remove the fan trays at the same time. Replace the fan trays one after another and finish replacing each fan tray within 2 minutes to prevent AI security engine modules from overheating and rebooting.

 

To replace a fan tray:

1.     Prepare an antistatic mat for placing the removed fan tray.

2.     Wear an ESD wrist strap. Make sure the wrist strap makes good skin contact and is reliably grounded.

3.     Loosen the captive screws on the fan tray.

4.     Holding the handles on the fan tray, pull the fan tray part way out of the slot. After the fans stop rotating, pull the fan tray out from the gateway.

5.     Place the removed fan tray on the antistatic mat.

6.     Install a new fan tray. For the installation procedure, see "Installing the gateway."

Replacing a power supply

	WARNING! ·     Provide a circuit breaker for each power supply. Before replacing a power supply, turn off the circuit breaker for it. ·     To reinstall the removed power supply in the chassis, wait until the status LED on it is off. ·     To avoid being hurt, allow a power supply to cool before removing it.

 

Power supply is also called "power module" in this document.

To avoid device damage and bodily injury, strictly follow the procedures shown in Figure 10 and Figure 11 to remove and install a power supply, respectively.

Figure 10 Power supply removal procedure

2.     Turn off the circuit breaker.

3.     Wear an ESD wrist strap, and make sure it makes good skin contact and is reliably grounded.

4.     Remove the cable tie, and then remove the power cord connector from the power supply.

5.     Press the latch on the power supply towards the handle direction and pull the power supply part way out of the slot.

6.     Holding the power supply handle with one hand and supporting the power supply bottom with the other, pull the power supply slowly out of the slot.

7.     Place the removed power supply on the antistatic mat.

8.     Install a new power supply. For information about the power supply installation procedure, see "Installing the gateway."
