CAUTION: SFP transceivers are keyed and can be properly inserted only one way. If the transceiver does not click when you insert it, remove it, turn it over, and then
3Remove the plastic protective cover, if fitted.
4Connect the fiber cable.
5The transceiver connects to the network using a duplex LC connector. Attach a male duplex LC con- nector on the network cable into the duplex LC con- nector on the transceiver.
6Connect the other end of the cable to a device fitted with an appropriate Gigabit Ethernet connection.
7Check the Module Active LEDs on the front of the Switch to ensure that it is operating correctly.
Removing an SFP Transceiver
Removing an SFP transceiver does not require power- ing off the Switch.
To remove an SFP transceiver:
1Disconnect the cable from the transceiver.
2Move the wire release lever downwards until it is pointing toward you.
3Pull 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 9.
Table 9 Items to Check
Item | Verify That |
|
|
Cabling | All external cabling connections are secure |
| and that no cables are pulled taut |
Cooling fan | Where possible, check that the cooling fan |
| is operating by listening to the unit. The |
| fan is fitted near to the front right hand |
| side of the unit (when viewed from the |
| front). |

If you experience any problems operating the Switch, refer to “Troubleshooting” starting on page 59.
