Replacing Modules
The ProCurve Switch 8100fl chassis supports three types of modules:

To replace a module, you must follow a different procedure for different
module types:

To avoid damaging modules and the backplane, be sure you are inserting the
right type of module into the slot type made for it.

Hot Swapping and Redundancy

All modules can be "hot swapped"; that is, they can be removed or installed
while the switch is powered on. However, note the following differences
between module types with respect to redundancy:

4-4
Switch fabric modules
(full-height module for 8116fl; or half-height module for 8108fl)
Management modules
Interface modules
For a fabric or interface module, you can remove the module from its slot
in the ProCurve 8100fl Switch chassis and install a new module in the
empty slot while the switch is powered on.
For a management module, you must first stop the module by entering the
halt command. Then remove the module from its slot and install a new
module.
When the primary switch fabric module fails, the redundant switch fabric
module takes over (in less than five seconds) and continues to function
as the primary module even after the failed module is replaced.
When hot swapping interface and switch fabric modules, use the CLI
redundancy switchover fabric-module lock command to prevent a redundant
switch fabric module from taking over as the primary switch fabric
module. Once the hot swap is completed, re-enable fabric protection
switching by using the redundancy switchover fabric-module clear command
When the primary management module fails, the redundant management
module takes over immediately as the new primary management module.
However, this new primary management module will reboot the other
modules resulting in a loss of traffic until all modules are back on line.
When the failed management module is replaced, the replacement
management module serves as the redundant management module.
