2. Grasping the edges of the transceiver, insert the it into the port until it is firmly seated. You can feel a small click when it
completely seats. If your transceiver has a bail, pull the bail up until it latches in the closed position.
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 step 1 through step 2 for the remaining QSFP ports.
5. Organize the cables. Refer to
Managing cables on page 86
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. The cable management comb is located above the modules on the port side of the chassis.
Brocade recommends the following best practices for cable management.
∙
Leave at least 1 m (3.28 ft.) of slack for each port cable. This provides room to remove and replace the device, allows for
inadvertent movement of the rack, and helps prevent the cables from being bent to less than the minimum bend radius.
∙
The minimum bend radius should be no smaller than ten times the cable radius. The minimum radius to which a 50 micron
cable can be bent under full tensile load is 5.1 cm (2 in.). For a cable under no tensile load, that minimum is 3.0 cm (1.2 in.).
∙
If ISL trunking is in use, group the cables by trunking group.
∙
Generally, Velcro
®
-type cable restraints are recommended to avoid creating sharp bends or kinks in the cables. Do not use tie
wraps with optical cables because they are easily overtightened and can damage the optic fibers.
∙
For easier maintenance, label the fiber-optic cables and record the devices to which they are connected.
∙
Do not route cables in front of the air intake vents.
∙
Route the cables to the top of the device through the cable comb.
NOTE
Keep LEDs visible by routing port cables and other cables away from the LEDs. See "Cabling Best Practices" (available at
http://www.brocade.com ) for cable management guidelines.
