Locating the communication adapter connector
Locate the individual connector in area A , (Figure 1-1 on page 1-4 )
for every cable to be plugged-in or unplugged. Figure 1-2 shows four
possible example configurations (that are fully populated):
1 All HSSs
2 All ELAs
3 Four TRAs with four HSSs
4 Four TRAs with four ELAs.

The numbers are the line numbers of the connectors. Your 3745 may
not be exactly the same: it may not be fully populated and may have a
different mixture of communication lines.

Deactivating the lines
If you are disconnecting any line (by removing a cable), ask the host
operator to deactivate all the lines to be unplugged.
Note: The line number is the same as the port number.
Then go to the following sections as needed:
"Unplugging or Plugging In an Ethernet LAN AUI Cable" on
page 1-7
"Unplugging or Plugging In a Token-Ring Adapter (TRA) Cable" on
page 1-11
