Installing the Series 4100gl Switches
Hot Swapping Switch Modules
If you want to continue with console management of the switch at this time
through either a direct connection or a telnet session, see chapter 3, “Getting
Started With Switch Configuration” for some basic configuration steps. For
more detailed information, refer to the
Management and Configuration
Guide
that is on the documentation CD-ROM that came with your switch.
Hot Swapping Switch Modules
The switch modules can be “hot swapped”, that is installed or replaced while
the switch is powered on. The procedures differ slightly, though between
adding new modules to an empty slot or replacing modules with the same type,
and exchanging the module with a different type.
Adding or Replacing Modules
If a module has to be replaced with one of the same type, or you are expanding
the switch capability by adding a module in a slot where one was not previ-
ously installed (since the last switch reboot), the replaced or new module is
immediately operational; there is no interruption to the switch operation.
Changing the Module Type
If you exchange a module with a different type of module though, for example
a 100/1000-T gl Module is installed in place of a 10/100-TX gl Module that was
in the slot, the switch must be rebooted after the new module is installed so
the switch processor can properly initialize and configure the new module
type.
You can reboot the switch by any of the following methods:
■
Pressing the Reset button on the front of the switch.
■
Unplugging and plugging in the power cord (power cycle). If two power
supplies are installed, both power cords would have to be unplugged.
■
issuing the
reboot system
command from the switch console CLI, or
selecting the Reset or Reboot option from the switch console menu, the
web browser interface, or HP ProCurve Manager for Hubs & Switches
Until the switch is rebooted, the module will not operate and the Module
Status LED for the affected slot will continue to flash.
