Adding or replacing switch modules with controlled
shutdown or hot swap methods
Aruba recommends using the CLI to shut down modules before removing them from the switch. This
provides a controlled shutdown process that minimizes trac loss and loss of function. However it also can
cause a longer delay in getting the replacement module operational. Hot swapping switch modules is also
supported, and enables faster module changeover, though it can also result in trac loss and some system
interruption.
Using controlled shut down to add or replace line modules.
If an empty line module slot is in the default conguration state, a module boots up when installed in the
slot. If there is a conguration mismatch between an installed module and the slot in which it is installed,
the module does not boot up. Use the procedures in this section to bring up a line module in cases where
the slot conguration is a mismatch for the line module.
Adding a line module to an empty, uncongured slot
Prerequisites
• Have an ESD wrist strap ready to use.
• Have available the line module you plan to install in the empty, uncongured slot. When installing a line
module in an uncongured slot, the module will be brought up as Admin-state up.
• Know the conguration you want on the selected slot.
Procedure
1. Put on a snugly tting ESD wrist strap and attach it to the ESD connector on the front of the switch. (See
Protect the switch and components from damage caused by ESD (Electrostatic discharge).)
2. Remove the blank slot cover from the chosen slot and store it for future use.
3. Install the module. As noted above, installing a line module in an uncongured slot brings the module up
as Admin-state up.
Replacing a line module with another of the same type
Prerequisites
Have an ESD wrist strap ready to use.
Have available the replacement line module you plan to install.
Procedure
1. Put on a snugly tting ESD wrist strap and attach it to the ESD connector on the front of the switch. (See .)
2. Use this command to deactivate the slot:
switch(config)# module <SLOT-ID> admin-state down
NOTE: The existing slot conguration remains.
