3Com C17302, 3C17300, C17304 manual Installing the Switch

Page 28

28CHAPTER 2: INSTALLING THE SWITCH

Use this transceiver to connect the Switch directly to a single-mode fiber-optic cable or to multimode fiber using a conditioned launch cable.

■1000BASE-LH70 GBIC 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.

■Fiber SC connector

■Type 4 GBIC with internal EEPROM fitted.

If the GBIC transceiver is faulty, it will not operate within the Switch. See “Solving Hardware Problems” on page 55.

Do not use non-3Com GBICs. If the GBIC transceiver is invalid it will not be recognised by the Switch.

Use the following sequence of steps to activate the GBIC ports.

1To insert one of the transceivers into a GBIC expansion port on the Switch:

a Orient the transceiver so that the fiber-optic duplex subscriber connector (SC) is toward you, as shown in Figure 7.

b Gently slide the transceiver into the GBIC port until it clicks into place.

2If you wish to remove the transceiver, compress the side tabs and gently pull the transceiver out of the port.

CAUTION: GBIC 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.
