Replacing an E4SA CRU

Caution: Apply equal pressure to both the top and bottom of the

E4SA CRU when pushing it into the slot to avoid damaging the

connector pins. If pins are damaged, both the E4SA CRU and the

backplane (or enclosure) must be replaced.

Push the E4SA CRU to the rear of the slot, but don't force the E4SA

CRU into the slot.

The figure shows how to install an E4SA CRU.

9 Press the blue-green tab on the E4SA CRU ejector and latch the ejector

to seat the E4SA CRU against the backplane.

10 Disconnect the grounding clip of your ESD wriststrap from the enclosure.

11 Connect the RJ-45 connectors to the Ethernet ports on the E4SA CRU.

Connect the other ends of the cables to your Ethernet hub. Use the

labels on the cables to make sure you connect each cable to the proper

port and Ethernet hub.
