Hot Swapping Line Cards

The procedure for hot swapping a line card consists of deactivating the line card, removing it from its slot in the SSR chassis, and installing a new line card in the slot.

Deactivating the Line Card

To deactivate the line card, do one of the following:

•Press the Hot Swap button on the line card. The Hot Swap button is recessed in the line card's front panel. Use a pen or similar object to reach it.

When you press the Hot Swap button, the Offline LED lights. Figure 2 shows the location of the Offline LED and Hot Swap button on a 1000Base-SX line card.

•Use the system hotswap out command in the CLI. For example, to deactivate the line card in slot 7, enter the following command in Enable mode:

ssr# system hotswap out slot 7

After you enter this command, the Offline LED on the line card lights, and messages appear on the console indicating the ports on the line card are inoperative.

Note: If you have deactivated a line card and want to activate it again, simply pull it from its slot and push it back in again. (Make sure the Offline LED is lit before you pull out the line card.) The line card is activated automatically.

Alternately, if you have not removed a line card you deactivated with the system hotswap out command, you can reactivate it with the system hotswap in command. For example, to reactivate a line card in slot 7, enter the following command in Enable mode:

ssr# system hotswap in slot 7
