Hot Swapping
Line Cards and
Control Modules
Hot Swapping Overview
This chapter describes the hot swapping functionality of the SSR. Hot swapping is the
ability to replace a line card or Control Module while the SSR is operating. Hot swapping
allows you to remove or install line cards without switching off or rebooting the SSR.
Swapped-in line cards are recognized by the SSR and begin functioning immediately after
they are installed.
On the SSR 8000 and 8600, you can hot swap line cards and secondary control modules.
On the SSR 8600, you can also hot swap the secondary switching fabric module.
This chapter provides instructions for the following tasks:
• Hot swapping line cards
• Hot swapping secondary Control Modules
• Hot swapping the secondary Switching Fabric Module (SSR 8600 only)
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.
