HSL Cables – Concurrent
This procedure will direct you through a concurrent maintenance procedure for
replacing the HSL cables. You do
not need to power the system or expansion tower
off.
1.
The following steps guide you through exchanging an HSL cable. You will need
to perform the following steps for both ends of the cable that you are replacing.
2. Disconnect the cable at the frame ID, card position, and port that you are
working on.
3. Is the connection an optical link?
No Yes
↓
Clean the HSL cable connectors on the new cables and the HSL cable
port using the tools and procedures listed in symbolic FRU
“OPT_CLN” on page 561. Go to step 5 of this procedure.
4.
Wait at least 30 seconds.
5. Connect the new cable to the port.
Attention: You must fully connect the cable and tighten the connector’s
screws within 30 seconds of when the cable makes contact with the port. If you
do not, the link will fail and you must disconnect and reconnect it again. If the
connector screws are not tightened errors will occur on the link and it will fail.
This ends the procedure.
