Premium Software Features
Additional Premium software features for this switch can be acquired by purchasing a Premium software license
and installing it on the switch.
For the most current information about the features included in the Premium license package, refer to the release
notes for your switch on the HP ProCurve Networking Web site at www.hp.com/go/procurve/manuals. The
Premium license is available from your ProCurve reseller.
Saving the Configuration After Installing or Exchanging a Module
The following cases automatically result in a change to the running-configuration on your switch:
■
Replacing a module with another module of a different type and then rebooting the switch
■
Installing a module in a slot that has not previously been used (including when you install a module
and apply power to the switch for the first time)
If you want to save such changes to permanent memory (startup-configuration file), use the write memory
command in the switch's command line interface (CLI). This causes the switch to use the current new hardware
configuration for subsequent reboots. (The switch always reboots from the startup-configuration file.)
If you do not save hardware changes to the startup-configuration file, you will be prompted with the following
message the next time you use the boot or reload command:
Do you want to save the current configuration [y/n]?
For more information on switch memory, including the startup-config and running-config memories, refer to the
Management and Configuration Guide. For the latest version of ProCurve switch documentation, visit

Module Hot Swap Operation Notes
One of the features of your 5400zl switch is the ability to "hot swap" the switch modules. You can install,
exchange, or remove modules after the switch has been powered on. Whenever a module is installed during this
process, it is initialized and tested for correct operation. During this process, the switch Self Test LED is on. If
you hot swap another module while the switch is initializing and testing the first module, it is possible to cause
the first module or the entire switch to be reset.
Hot Swap Precautionary Procedures. To prevent the modules or switch from being reset when you must hot
swap multiple modules, follow these simple precautions:
■ Before removing or installing any modules, make sure that all network cables are disconnected from
the module. Do not remove any modules from the switch while the switch Self Test LED is lit.
