Installing a Passive SCM in a CSS 11506
You can install a passive SCM in a CSS 11506 chassis. A passive module is a
stand-by module in case of an active module failure. As implemented in
WebNS 5.10 and greater, if the active SCM fails:
1. The CSS reboots and connections are terminated.
2. The CSS restores all configurations using the startup-config file.
3. The passive SCM becomes active automatically.
Note Passive modules do not load share processing functions with the active module.
To install a passive SCM:
1. Properly ground yourself prior to handling the module.
2. As defined in Table 1-3, SCMs are restricted to slots 1 or 2.
3. If the CSS is powered up, power it down.
4. If necessary, remove a blank panel from the chassis to expose the slot.
5. Insert the module into the board guides at the left and right of the slot and
slide it into the chassis by pressing firmly at the left and right of the faceplate.
6. Extend both ejectors simultaneously to seat the module connector into the
backplane.
7. Using a Phillips screwdriver, tighten the spring-loaded screws on the front of
the module faceplate.
