Figure 4–25 Removing the Ethernet ID ROM
CAUTION
Do not bend the pins on the ROM. You must add this ROM to
the replacement system module. The Ethernet ID ROM key
must face the back of the system. If you put the Ethernet ID
ROM in backwards, the system will not function properly. See
Figure 4–25 for the proper orientation of the Ethernet ID ROM
key.
To replace a system module:
1. Remove the Ethernet ID ROM from the new system module and
reinstall it on the old system module.
2. Take the Ethernet ID ROM you removed from the old system module
and insert it in the new system module. Use Figure 4–25 as a
reference. The key faces the rear of the module.
