variety of ways, for example, using cable channels on the sides of the rack or patch panels to minimize
cable management. Following is a list of additonal recommendations:
•
Plan for rack space required for cable management before installing the device.
•
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.
•
For easier maintenance, label the fiber-optic cables and record the devices to which they are
connected.
•
Keep LEDs visible by routing port cables and other cables away from the LEDs.
•
Do not route the cables in front of air vents.
•
Use Velcro ® type straps to secure and organize fiber-optic cables.
•
Route the cables away from LEDs to keep them visible.
•
Use the cable management comb that attaches to the chassis for simple cable management. The
comb can be installed without service disruption.
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.
Note
Do not use tie wraps with optical cables because they are easily overtightened and can
damage the optic fibers.
Installing an SFP+ transceiver
While non-Extreme optics are supported,Extreme-qualified transceivers are recommended. The port
might not become operational using unqualified transceivers.
To insert an SFP+ transceiver, complete the following steps.
Note
Route cables to the side so that the line cards can be removed without disturbing the cables
to the other line cards.
Note
Always use the pull tab to insert or remove transceivers as they might be hot.
1. Perform one of the following steps, depending on your transceiver type.
•
If the transceiver uses a pull tab, use the pull tab to help push the transceiver into the port until it
is firmly seated and the latching mechanism clicks.
