Pluggable Transceiver Modules
Extreme Networks oers several optical transceiver modules for transmitting and receiving data over
optical fiber rather than through electrical wires.
Note
A small flat-blade screwdriver can be used to free an obstructed bale clasp on an optical
module.
Optical Cables
Direct-attach copper and fiber cables provide connections between populated SFP+, SFP28, QSFP+,
and QSFP28 ports.

Connect Network Interface Cables
Use the appropriate type of cable to connect the ports of your switch to another switch or router.
Cable Type Maximum Distance
CAT5E 55 meters
CAT6 55 meters
CAT6A 100 meters
Working carefully, one port at a time, do the following:
1. Verify that you have identified the correct cable for the port.
2. Use an alcohol wipe or other appropriate cleaning agent to clean the cable connectors; make sure
they are free of dust, oil, and other contaminants.
3. If you are using optical fiber cable, align the transmit (Tx) and receive (Rx) connectors with the
correct corresponding connectors on the switch or the I/O module.
4. Press the cable connectors into their mating connectors on the switch or I/O module until the cable
connector is firmly seated.
5. Repeat the preceding steps for the remaining cables on this or other switches or I/O modules.
