Replacing storage network cables or transceivers

This section describes how to replace storage network cables or transceivers.

Procedure performed by: Customer or field service

Replacing a cable or transceiver that connects the storage controller to an interconnect can be done live, without any specific preparation steps.

When a cable or transceiver is disconnected, the storage controller associated with the port will decrease in bandwidth by up to 25%. Disconnecting all four cables results in zero bandwidth to the controller, which may trigger failover to the other controller. If there is only one interconnect in the chassis, disconnecting all cables results in taking the storage offline as there is no failover option.
