Replacing a Switch Fabric Module
You can remove a switch fabric module and replace it with a new one while the NetIron MLX Series chassis is
powered on and running. For more information on slot locations, see“Chassis” on page 2-2
NOTE:
A NetIron MLX Series switch fabric module is dedicated, which means that it functions properly in the
NetIron MLX Series chassis only. If you attempt to install a NetIron MLX Series switch fabric module in another
Foundry chassis or a switch fabric module intended for another Foundry chassis in a NetIron MLX Series chassis,
the chassis and switch fabric module may not function properly.
CAUTION:
If hot removing or inserting a module, please 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.
This section provides information about the following tasks:

Removing a Switch Fabric Module
For a graceful shutdown of the links, Foundry recommends that you disable the switch fabric module before
removing it from the NetIron MLX Series chassis by following the instructions below.
Before removing a switch fabric module from the NetIron MLX Series chassis, have the following on hand:
•
An ESD wrist strap with a plug for connection to the ESD connector on the NetIron MLX Series chassis
WARNING:
For safety reasons, the ESD wrist strap should contain a 1 meg ohm series resistor.
•
A large flat-head screwdriver
To remove a switch fabric module from the NetIron MLX Series chassis, do the following:
1.
Disable the module by entering the
power-off snm
<slot-number> command at the Privileged EXEC level of
the CLI. For the <slot-number> parameter, specify 1 - 3 for NetIron MLX-4, 1 - 3 for NetIron MLX-8, 1 - 4 for
NetIron MLX-16, or 1 - 8 for NetIron MLX-32.
2.
Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector on the chassis.
3.
Using the flathead screwdriver, loosen the two screws on the ends of the module.
4.
Pull the card ejectors towards you, and away from the module front panel. This action unseats the module
from the backplane.
5.
Pull the module out of the chassis, and place in an anti-static bag for storage if desired.
6.
Install a new switch fabric module in the slot. For information about performing this task, see “Installing a New
Switch Fabric Module” on page 6-8.
Installing a New Switch Fabric Module
NOTE:
A NetIron MLX Series switch fabric module is dedicated, which means that it functions properly in the
NetIron MLX Series chassis only. If you attempt to install a NetIron MLX Series switch fabric module in another
Foundry chassis or a switch fabric module intended for another Foundry chassis in the NetIron MLX Series
chassis, the chassis and switch fabric module will not function properly.
Before installing a new switch fabric module into the NetIron MLX Series chassis, have the following on hand:
•
A new switch fabric module, which you can order from Foundry
•
An ESD wrist strap with a plug for connection to the ESD connector on the NetIron MLX Series chassis
