Replacing cables
If you suspect a cable is faulty, check its continuity on all pins. If you need to replace a
cable, refer to
“Field Replaceable Units (FRUs)” on page 129 for part numbers. See below
for cable locations.
When removing a cable, be sure to note the routing. Be sure to route the new cable in the
same manner.
Replacing PROMs
Please read the information in “Propaq CS Monitor software” on page 59.
The PROMs require a special removal tool to replace them. See “Required tools” on
page 60. To prevent damage to the PROM sockets, do not use any other tools.
The following instructions describe how to replace PROMs:
• To remove the PROMs, insert the fingers of the PROM removal tool into the slots at
two corners of the PROM and pull out the PROM, while squeezing the legs against
the PROM.
• To load the new PROM, align the beveled corner of the PROM with beveled OUTSIDE
corner of the socket. Carefully press the new PROM into place.
