4. 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.
Note
If your transceiver has an integrated cable attached, you will not install a cable.
When both ends of the cable are inserted and the link is fully established, the LED displays steady
green.
Note
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.
5. Organize cables to avoid covering LEDs and air vents. Refer to
on page 65 for more
information.
Breakout cables
The copper breakout cables are terminated with optical connectors and are available in 1m, 3m, 5m, and
greater lengths. No additional connectors or cabling are required when using the copper breakout.
When using the fiber breakout cables, additional 10Gb optics are required.
For the SLX 9640 device interfaces 0/25 to 0/36 support up to 48 10GbE or 48 25GgE ports in
breakout mode by using the following optics:
For 4 x 10Gbe breakout:
•
4 SFP+ 40GbE-to-10GbE copper breakout cables in 1m, 3m, or 5m or greater lengths.
•
40G-QSFP-SR4-INT (with fiber breakout cables and additional 10GbE optics).
