Fiber cabling is required for direct attachment to Gigabit NICs or switches and routers through fiber ports.
Connecting a network device to a fiber port
For direct attachment from the Brocade device to a Gigabit NIC, switch, or router, fiber cabling with an LC connector is required.
Testing connectivity
After you install the network cables, you can test network connectivity to other devices by observing the LEDs related to network
connection and performing trace routes.
Installing transceivers and attaching cables
The following two sets of steps cover the installation of transceivers and cables for most SFP and for QSFP transceivers.
CAUTION
Before plugging a cable into any port, be sure to discharge the voltage stored on the cable by touching the electrical contacts to
ground surface.
Installing SFP and SFP+ transceivers and cables
Complete the following steps to install optical SFP and SFP+ transceivers.
1. Add the transceivers and cables to the line card ports.
Position one of the optical transceivers so that the key is oriented correctly to the port. Insert the transceiver into the port until it
is firmly seated and the latching mechanism clicks.
Transceivers are keyed so that they can only be inserted with the correct orientation. If a transceiver does not slide in easily,
ensure that it is correctly oriented.
2. Position a cable so that the key (the ridge on one side of the cable connector) is aligned with the slot in the transceiver. Insert the
cable into the transceiver until the latching mechanism clicks.
Cables are keyed so that they can be inserted in only one way. If a cable does not slide in easily, ensure that it is correctly
oriented.
3. Repeat step 1 and step 2 for the remaining ports.
4. If you are using direct-attach cables, you can insert them at this time.
5. Organize the cables. Refer to
Managing cables on page 86
6. Verify the device port status using the show interface command.
7.
Verify fabric connectivity using the show fabric all command.
Installing QSFP transceivers and cables
Complete the following steps to install the QSFP transceivers and cables in the 12x40 GbE and 27x40 GbE line cards.
Because each QSFP transceiver consists of four 10 GbE ports, be aware that any problems with one port could affect all four ports in the
quad.
1. Position one of the QSFP transceivers so that the key is oriented correctly to the port.
