Line Cards
Line Cards
• Hold the module only by its edges or front panel.
• Wear an anti-static wristband connected to a suitable earth ground whenever handling the
module.
• Store or transport this module only in appropriate anti-static packaging.
The procedure for hot swapping a line card consists of deactivating the line card, removing it from
its slot in the X-Pedition chassis, and installing a new line card in the slot. When removing a line
card from the router, note the following:
• Whenever a user hot swaps any line card out of the router, SmartTRUNK links configured with
the Huntgroup protocol may go down for a few seconds.
• All commands associated with a module that is hot swapped out of the router are marked with
an “E” in the configuration.
Deactivating the Line Card
To deactivate the line card, use either of the following methods:
• Press the Hot Swap button on the line card. The Hot Swap button is recessed in the line card's
front panel—use the tip of a pen or similar object to reach it.
Before pressing the Hot Swap button, only the online LED is lit. After pressing the Hot Swap
button, the ofline/online LEDs toggle briefly to indicate that the sytem has begun the process of
hot swapping the line card. Once the router finishes the hot swap process, the offline LED will
light and the module will be ready to remove. The amount of time required to hot swap the
module depends upon the number of configuration lines that use the module and how busy the
sytem is.
