2. Press the Hot Swap button or enter the following from the CLI:
3. When the module is ready to remove, the Offline LED will turn ON and all other LEDs will
turn OFF. Figure 3 shows the location of the LEDs and Hot Swap buttons on Control
Modules.

open the ejectors.
5. Carefully remove the Control Module from the chassis.
Installing a Control Module
xp# system hotswap out slot
Note: If you have deactivated a Control Module and want to activate it again, simply pull it
from its slot and push it back in again. The module is activated automatically. If you
deactivated the module with the system hotswap out command but did not remove
the module, you can reactivate it with the system hotswap in command:
xp# system hotswap in slot 1
WARNING The X-Pedition and its components are sensitive to static discharge. To prevent
electrostatic damage, observe the guidelines provided in Preventing Electrostatic
Damage on page 17.
To install a Control Module, do the following:
1. Slide the new Control Module all the way into the slot, firmly but gently pressing it in place
to ensure that the pins on the back of the card are completely seated in the backplane. Make
sure the circuit card (and not the metal plate) is between the card guides. Check both the upper
and lower tracks.
Note: On an XP-8000/8600, you can install either a line card or a Control Module in slot CM/1,
but you can install only a Control Module in slot CM. On the ER16, control modules will
operate only in slots 8 and 9—slot 8 is reserved for the Primary control module.
WARNING You must install the PCMCIA card before you install the CM or while the CM is
on standby after a hot swap. Do not remove a PCMCIA card while the unit is
powered on. Enterasys recommends using PCMCIA cards of the same size and type
when operating in a Dual CM environment.
2. Secure the Control Module. To secure the control module in an ER16, close the ejectors and
use a flathead screwdriver to tighten the screw on each ejector. For all other routers, align the
captive screws with the holes in the face of the router and tighten to secure the module to the
chassis.
