Brocade Communications Systems Brocade VDX 8770-4 Manual De Usuario

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 

 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 

6. Verify the Brocade VDX 8770-4 and 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 12x40G 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. 

2. Using the tab, insert the transceiver into the port until it is firmly seated. You can feel a small click when it 

completely seats.

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.

When the transceiver is correctly seated, the status LED will turn solid amber.

3. Remove the protective plug from the QSFP transceiver and the protective cap from the special QSFP cable and 

insert it into the transceiver until it is firmly seated.

The cables are also keyed to fit into the transceivers correctly. 

When the cable is correctly seated, the status LED will change from amber to green.

4. Repeat 

 through 

 for the remaining QSFP ports.

5. Organize the cables. Refer to 

Managing cables

Cables can be organized and managed in a variety of ways; for example, using cable channels on the port sides of 
the rack or patch panels to minimize cable management. With the horizontal orientation of the line cards in the 
Brocade VDX 8770-4, a pair of vertical cable management finger assemblies have been provided to keep the cables 
from hanging down in front of other modules.
