The DMM enables you to verify each network connection (both active
and isolated) for all CoreBuilder 5000 modules and NMC cards installed
in your hub. To initiate the verification process:
1 Press the Display Control Toggle button on the front of the module.
2 Observe as the DMM sequentially cycles through each network
connection (Ethernet, Token Ring, then FDDI) and lights each status LED
associated with the network indicated on the DMM LCD display.
All isolated networks (1 through 11) light at the same time, rather than
one by one.
