3.6 SFP+ Cable Replacement Procedure
The SFP+ cable connected to a Controller Node is a
10G SFP+ SFP+ 3m DAC Cable, 30AWG
.
Prerequisites
None.
Required Tools
None.
To replace an SFP+ cable, proceed as follows:
1.
Identify the faulty SFP+ cable.
a) Go to the back of the rack.
b) Look for the Controller Node with a faulty SFP+ cable.
Each Controller Node has an SFP+ cable with an SFP+ optical transceiver attached in ports
N1
and
N4
as shown
in the figure below. The faulty cable has an amber LED illuminated on its metal connector.

2.
Remove the faulty SFP+ cable from the Controller Node.
a) Pull the SFP+ optical transceiver out of the Controller Node.
b) Unlatch the faulty SFP+ cable from the SFP+ optical transceiver by pulling very gently on its pull tab.
Once the latch is disengaged, the cable is loose.
c) While pulling gently on its pull tab, grasp its metal connector or cord to pull the cable out of its port.
Warning:
Do not pull the cable out by its pull tab, because the pull tab might break.
3.
Install the new SFP+ cable.
a) Connect the new SFP+ cable to the SFP+ optical transceiver you removed from the Controller Node port.
The cable is reseated properly (the latch is engaged) when you hear a click.
b) Push the SFP+ optical transceiver into the same Controller Node port.
4.
Verify that the amber LED on the SFP+ optical transceiver is off.
