22 Instaling the Switch To access the latest list of approved SFP transceivers for the Switch on the 3Com Web site, enter this URL into your Internet browser: http://www.3Com.com 3Com recommends using 3Com SFPs in the Switch. If you insert an SFP transceiver that is not supported, the Switch will not recognize it. Inserting an SFP Transceiver To be recognized as valid, the SFP transceiver must have the following characteristics: • 1000BASE-SX or 1000BASE-LX media type: o 1000BASE-SX SFP transceiver Use this transceiver to connect the Switch directly to a multimode fiber-optic cable. o 1000BASE-LX SFP transceiver Use this transceiver to connect the Switch directly to a single mode fiber-optic cable or to multimode fiber using a conditioned launch cable. If the SFP transceiver is faulty, it will not operate within the Switch. Non-3Com SFPs may not be recognised To activate the SFP port: 1. Hold the transceiver so that the fiber connector is toward you and the product label is visible. Ensure the wire release lever is closed (in the upright position). 2. Gently slide the transceiver into the SFP slot until it clicks into place. 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 reinsert it. 3. Remove the plastic protective cover, if fitted. 4. Connect the fiber cable. 5. Attach a male duplex LC connector on the network cable into the duplex LC connector on the transceiver. 6. Connect the other end of the cable to a device fitted with an appropriate Gigabit Ethernet connection. 7. Check the Module Active LED on the front of the Switch to ensure that the SFP transceiver is operating correctly. 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.

Instaling the Switch
To access the latest list of approved SFP transceivers for the Switch on the 3Com Web site, enter

3Com recommends using 3Com SFPs in the Switch. If you insert an SFP
transceiver that is not supported, the Switch will not recognize it.
Inserting an SFP Transceiver
To be recognized as valid, the SFP transceiver must have the following characteristics:
•
1000BASE-SX or 1000BASE-LX media type:
o
1000BASE-SX SFP transceiver
Use this transceiver to connect the Switch directly to a multimode fiber-optic
cable.
o
1000BASE-LX SFP transceiver
Use this transceiver to connect the Switch directly to a single mode fiber-optic
cable or to multimode fiber using a conditioned launch cable.
If the SFP transceiver is faulty, it will not operate within the Switch.
Non-3Com SFPs may not be recognised
To activate the SFP port:
1.
Hold the transceiver so that the fiber connector is toward you and the product label is
visible. Ensure the wire release lever is closed (in the upright position).
2.
Gently slide the transceiver into the SFP slot until it clicks into place.
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 reinsert it.
3.
Remove the plastic protective cover, if fitted.
4.
Connect the fiber cable.
5.
Attach a male duplex LC connector on the network cable into the duplex LC connector
on the transceiver.
6.
Connect the other end of the cable to a device fitted with an appropriate Gigabit
Ethernet connection.
7.
Check the Module Active LED on the front of the Switch to ensure that the SFP
transceiver is operating correctly.

Removing an SFP transceiver does not require powering off the Switch.
To remove an SFP transceiver:
1.
