HSL cables - concurrent

For use by authorized service providers.
Use this procedure to replace the HSL cables concurrently. You will need to perform the following steps for
both ends of the cable that you are replacing.
Warning: If an HSL cable is pulled accidentally, it may result in the HSL connection being lost to frames
that were in a loop. If this occurs, follow the Power down, power on instructions (See page 200) below to
power down the frames, reconnect the HSL cable, and power the frames back on.
Note: You do not need to power off the system or expansion unit. If you are replacing a cable between a
system unit and an expansion unit, connect the expansion unit end of the cable first.
1. Disconnect the cable at the frame ID, card position, and port that you are working on.
2. Is the connection an optical link?
v No: Wait at least 30 seconds.
v 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. Continue with the next step.
3. 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.
