Chapter 15 Connecting Temporary Terminal and Attaching Peripherals
The BPX Control and Auxiliary ports are pinned as RS-232/V.24 DCE ports. When connecting a
terminal, PC, or other device pinned as RS-232/V.24 DTE to the Control or Auxiliary port, you may use
a straight-through cable. However, to connect a modem to the Control or Auxiliary ports, you must use
a null-modem cable.
In these procedures:
• The term BCC refers to the BCC-4V, BCC-3-32M, BCC-3-64M, or BCC-32
• The BCC-4V, BCC-3-32M, and BCC-3-64M require BCC-3-BC backcards
The BCC-32 requires the BCC15-BC backcard
•
To attach a terminal to the BPX switch:
From the back of the cabinet, run the control terminal RS-232/V.24 cable through the opening at the
Step 1
bottom and up to the LM-BCC card in back slot 7.
For nodes with a single BCC: Locate the CONTROL port connector on the LM-BCC in slot 7.
Step 2
Attach the RS-232/V.24 cable as shown in Figure 15-1, then proceed to Step 5.
Step 3 For nodes with redundant BCCs: A single cable is sufficient for temporarily connecting to the
CONTROL port of the active BCC during initial node configuration. However, if you want to monitor
the switchover function of the BCCs via the CONTROL port without swapping the cable from the
CONTROL port of one BCC to the CONTROL port of the other, you can use a Y-cable.
Connect one leg of the Y-cable to the CONTROL port connector on the backcard in slot 7 and the other
leg to the slot 8 CONTROL port connector.
Step 4 Attach a RS-232/V.24 cable to the remaining leg of the Y-cable as shown in
Figure 15-2.
Step 5 Fasten the cable connector to the CONTROL port connector with the captive screws on the connector
hood.
Plug the control terminal (or Cisco WAN Manager) power cord into the appropriate wall receptacle (115
Step 6
VAC or 240 VAC) and switch it on.
Step 7 If connecting to a Cisco WAN Manager workstation, set the port function for VT100/StrataView by
using the cnftermfunc command.
If using a "dumb" terminal, select VT100 only (# 5).
Step 8 Make sure that the CONTROL port and the terminal or workstation are set to the same baud rate and
check the other communication parameters by using the cnfterm command.
Step 9 When you have completed the initial node configuration, remove the connections to the CONTROL
Ports. Network Management connections are described in the next section.
Note When a node is powered up, it enters "boot mode" which has a default speed of 9600 bps.
If the node's control port has been previously configured to 19,200, the first messages will
appear garbled because the terminal is at 19,200 bps, but the control port (in "boot mode")
is temporarily at 9,600 bps. When the "transition to online" occurs, then the speeds will
match and the terminal display will be readable.
