“Taking the Host Subsystem Offline” on page 96). To replace an SCB, use the following procedures:
■Operating and Positioning the SCB Ejectors on page 98
■Removing an SCB on page 99
■Installing an SCB on page 100
Operating and Positioning the SCB Ejectors
■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.
