Replacing an SCB
The services gateway can have up to two SCBs. They are located in the front of the
chassis in the slots marked
approximately 9.6 lb (4.4 kg).
Before you replace an SCB or a Routing Engine, you must power off the services
gateway (see "Powering Off the Services Gateway" on page 70). To replace an SCB,
use the following procedures:

When removing or inserting an SCB, ensure that the SCBs or blank panels in
adjacent slots are fully inserted to avoid hitting them with the ejector handles.
The ejector handles require that all adjacent components be completely inserted
so the ejector handles do not hit them, which could result in damage.
The ejector handles have a center of rotation and need to be stored toward the
center of the board. Ensure the long ends of the ejectors located at both the top
and the bottom of the board are vertical and pressed as far as possible towards
the center of the board.
To insert or remove the SCB, slide the ejector across the SCB vertically, rotate
it, and slide it again another quarter of a turn. Turn the ejector again and repeat
as necessary. Utilize the indexing feature to maximize leverage and to avoid
hitting any adjacent components.
Operate both ejector handles simultaneously. The insertion force on an SCB is
too great for one ejector.
