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 rotate. After you install the SCBs in the router, ensure that
the ejectors are positioned horizontally and do not block any other components
or the LEDs. To avoid blocking the visibility of the LEDs, position the ejectors
over the PARK icon.
To insert or remove the SCB, slide the ejector across the SCB horizontally, 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.
