Installing a PowerConnect B-MLXe-16 router
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 PowerConnect B-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:
NetIron# set-fan-speed auto
The PowerConnect B-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.
Slot blank removal steps
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.
Module installation steps
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
64
different module type, remove the old configuration information using this procedure:
a. Use the show running-config command in config mode to determine the current
configuration of the slot.
MLXe-16(config)# show running-config
Current configuration:
!
ver V5.1.0aT163
module 1 ni-mlx-24-port-1g-copper
!
This example shows that slot 1 is currently configured for a 24-port 1 Gbps copper
interface module.
