Replacing PROMs

Please read the information in
The PROMs require a special removal tool to replace them. See
page 60. To prevent damage to the PROM sockets, do not use any other tools.
The following instructions describe how to replace PROMs:
Note
• 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.
