WARNING!
Mini-GBICs contain Class 1 lasers. Invisible laser radiation can occur when laser connections are unplugged. Do not
stare into the beam. This device is compliant with FCC 21 CFR 1040.10 and EN60825-1 A2:2001.
WARNING!
To prevent ESD damage to a mini-GBIC, always use an appropriately grounded ESD-preventive wrist strap when
installing or removing the module. Handle the module by its sides only. Never touch the card-edge connectors at the
insertion end of the module.
To insert a mini-GBIC:
1 Holding the mini-GBIC by its sides, insert the mini-GBIC into the port on the switch.
2 Slide the mini-GBIC into the port, until you hear it click. If the mini-GBIC has a handle, push up on
the handle to secure the mini-GBIC.
NOTE
Remove the LC fiber-optic connector from the mini-GBIC before removing the mini-GBIC from the port.
To remove a mini-GBIC:
1 Disconnect the optical cable from the mini-GBIC.
2 Unlatch the mini-GBIC in one of the following ways:
●
On a mini-GBIC similar to Module A in Figure 238 , press and hold the black plastic tab at the
bottom of the connector.
●
On a mini-GBIC similar to Module B, Module C, or Module D in Figure 238 , rotate the front
handle down.
3 Pull the mini-GBIC out of the port on the switch.
Connecting Fiber Cables
Before you connect fiber cables to the dual-speed 100FX/1000LX mini-GBIC or the LX100 mini-GBIC,
note the following information about these mini-GBICs.
100FX/1000LX Mini-GBIC. The 100FX/1000LX mini-GBIC complies with the 100FX-SMF standard. In
order to use the 100FX/1000LX mini-GBIC in 100FX-MMF operation, a minimum attenuation of 6 dB is
required. After the mini-GBIC is installed, connect a 6-dB attenuator to the transmitter side (Tx) of the
mini-GBIC. Then connect the attenuator to the single-mode end of a mode conditioning patch cord. The
mode conditioning patch cord transitions the mini-GBIC from SMF to MMF operation.
LX100 Mini-GBIC. To prevent permanent damage to the LX100 mini-GBIC, always check the optical
input power of the receiver before you insert the fiber cable. The maximum optical input power is -9
dBm. If you use an optical loopback for diagnostics, the loopback requires a minimum of 12 dB optical
attenuation. The recommended attenuation range is 12 to 20 dB.
