Removing an SFP Transceiver Removing an SFP transceiver does not require powering off the Switch. To remove an SFP transceiver: 1 Disconnect the cable from the transceiver. 2 Move the wire release lever downwards until it is pointing toward you. 3 Pull the wire release lever toward you to release the catch mechanism. The SFP transceiver should slide out easily. Performing Spot Checks At frequent intervals, you should visually check the Switch. Regular checks can give you an early warning of a possible failure; any problems can then be attended to when there will be least effect on users. 3Com recommends periodically checking the items listed in Table 6.
