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.
Step 5
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
