Installing A Qsfp28 Transceiver - Extreme Networks ExtremeRouting SLX 9740 Hardware Installation Manual

Transceivers and Cables
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 a QSFP28 transceiver

While non-Extreme optics are supported, Extreme-qualified transceivers are recommended. The port
might not become operational or it may have a higher error rate using unqualified transceivers.
The following additional notes apply to the QSFP28 transceivers:
•
While non-Extreme optics are supported,Extreme-qualified transceivers are recommended.
If using 40GbE-to-10GbE breakouts, each QSFP28 transceiver contains four individual 10 GbE ports.
Be aware that any problems with one port could affect all four ports in the quad if the QSFP28 must
be replaced.
•
Some QSFP28 transceivers have an integrated cable attached. You do not need to install a separate
cable.
To insert an QSFP28 transceiver and cable, complete the following steps.
1. Push the transceiver into the port using the pull tab. 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. Push the correctly oriented transceiver into the port until it is firmly seated and the latching
mechanism clicks.
Note
Always use the transceiver pull tab to insert or remove the QSFP28 transceivers, as the
transceiver might be hot.
