2 Installing a Brocade MLXe-16 router

DANGER

For safety reasons, the ESD wrist strap should contain a 1 megohm series resistor.

CAUTION

Use of a power screwdriver may twist the heads from the screws and is not recommended.

CAUTION

If you do not install a module in a slot, you must keep the slot blank in place. If you operate the router with an uncovered slot, the system may overheat. Tighten the screws that secure the slot blanks so that they remain in place when removing adjacent panels or modules.

Reset fan speed to auto

For Brocade MLXe 16-slot routers, if you insert a module into a slot where the fan speed for a previous module was manually configured, you will need to change the fan speed back to auto. For example, if the fan speed was manually configured to “slow”, and you are installing a module that requires more cooling power, the “slow” setting will cause the module to overheat. To configure the fan speed to auto, enter the following command:

Brocade# set-fan-speed auto

The Brocade MLXe-16 router ships with slot blanks installed in all empty module slots. The slot blanks help ensure proper airflow inside the router. You must remove the slot blank to install a module in a slot.

Although the slot blanks differ in size, the procedure for removing them is identical. You will need a flat-blade screwdriver to perform this task.

Follow these steps to remove a slot blank.

1.Loosen the screws on either end of the slot blank by hand or with a flat-blade screwdriver.

2.Pull the slot blank out of the router and store it in a safe place for future use.

CAUTION

If you are hot-swapping a module, allow a minimum of two seconds after a module (or power supply or fan tray) has been removed before inserting a module in the same slot.

Follow this procedure to install modules in the router.

1.If you are installing a module in a slot which may have been previously configured for a different module type, remove the old configuration information using this procedure:

a.Use the show running-configcommand in config mode to determine the current configuration of the slot.

MLXe-16(config)# show running-config Current configuration:
