Connecting Temporary Terminal and Attaching Peripherals

This chapter explains how to set up a temporary terminal or network management station for initial power-up and to attach other peripherals.

Contents of this chapter include:

• Temporarily Connecting a Terminal or NMS to the Control Port

• Connecting a Network Printer to the BPX Switch

• Connecting Dial-In and Dial-Out Modems

• Making External Clock Connections

A network must have at least one connection to a control terminal or Cisco WAN Manager network management workstation. You use the Cisco WAN Manager network management workstation to configure and maintain all nodes in a network and report network statistical data.

If you wish to print, a network printer may be connected to the auxiliary port.

If you want to have Cisco Customer Service perform remote troubleshooting, you must attach a dial-in modem to the network. For more information, see the Connecting Dial-In and Dial-Out Modems section.

Before proceeding to this chapter, you should first complete the procedures in:

• "Connecting Cables"

• Chapter 13, "Installing the BPX Switch Cards"

and before that, the procedures in either:

• "Installing the DC Shelf"

• "Installing the AC Shelf"

and

• "Installing the T3/E3 Cable Management Tray"

and before that, the procedures in either:

• "Installation with Cisco Cabinets including 7000 Series Routers"

or

• "Installation in Customer Cabinet"

Before attempting to attach equipment to the BPX switch, read the manufacturer literature to ensure that you have made the equipment ready for attachment.

For the pin assignments for the BPX switch control terminal port, see "BPX Switch Cabling Summary."

For additional information, refer to the following documents:

•For instructions on using the switch commands, refer to the Cisco WAN Switching Command Reference.

•For instructions on using the Cisco WAN Manager workstation, refer to the Cisco WAN Manager User's Guide.

Temporarily Connecting a Terminal or NMS to the Control Port

You must connect to a basic VT-100 type terminal (or PC or workstation, including a Cisco WAN Manager workstation) to the BPX control port for use in entering commands to bring up a new node. This temporary or local control is especially useful during installation, initial power-up, and configuration.

To support the Cisco WAN Manager workstation, the BPX switch LM-BCC back card offers the following ports for attaching peripherals:

•A RS-232 serial data port labeled CONTROL port

•A RS-232 serial data port labeled AUXILIARY port

•An Ethernet port labeled LAN

A Cisco WAN Manager workstation is recommended for managing a network containing the IGX and BPX switches. For setup instructions and specifications for network alarm, control, and statistics monitoring for the Cisco WAN Manager network management system, refer to the Cisco WAN Manager User's Guide.

Note For network management, a Cisco WAN Manager workstation must be connected to the LAN port of one or more network nodes. Because BPX switches provide processing power for network management, it is not connected to the control port during normal operation.

The data configuration for the BPX control port is described in Table 15-1.

Table 15-1 Control Port Parameters for Local Control (PC or Workstation)

Parameter

Setting

BPX switch Port Used:

Serial CONTROL port, located on a BCC back card, is used to interface to a local terminal.

Code:

Standard 7 or 8-bit ASCII; 1 or 2 stop-bits; even, odd or no parity.

Interface:

RS-232 DCE.

Data Rate:

All standard asynchronous data rates from 300 to 19200 bps, independently software-selectable.

Supported Terminals:

Any terminal compatible with DEC VT-100.

Cable Required:

Straight-through RS-232 cable.

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.

The following cards are related to the procedures:

•The 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 back cards.

•The BCC-32 requires the BCC15-BC back card.

To attach a terminal to the BPX switch, use the following procedure:

Step 1 From the back of the cabinet, run the control terminal RS-232/V.24 cable through the opening at the bottom and up to the LM-BCC card in back slot 7.

Step 2 For nodes with a single BCC: Locate the CONTROL port connector on the LM-BCC in slot 7.
Attach the RS-232/V.24 cable as shown in Figure 15-1. Go 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 through 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 back card 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.

Step 6 Plug the control terminal (or Cisco WAN Manager) power cord into the appropriate wall receptacle (115 VAC or 240 VAC) and switch it on.

Step 7 Use the cnftermfunc command to set the port function as follows:

Next Command: cnftermfunc {a|c}[index]

Note If you are using a "dumb" terminal, enter 2 as the index parameter to select VT100 only.

For parameter definitions that are used for the cnftermfunc command, refer to the Cisco WAN Switching Command Reference, Release 9.3.30.

Step 8 Enter c for the Control port.

Step 9 Enter 1 as the index parameter to set VT100/StrataView.

Step 10 Use the cnfterm command (Go to Step 8) to check the other data transmission parameters as follows:

Next Command: cnfterm {a|c}[baud rate][data bits][stop bits][output flow control{x|n}][input flow control{x|n}][CTS flow{x|n}][DTR{y|n}]

For parameter definitions that are used for the cnfterm command, refer to the Cisco WAN Switching Command Reference, Release 9.3.30.

Step 11 Ensure that the control port, terminal, or workstation are set to the same baud rate.

Step 12 When you have completed the initial node configuration, remove the connections to the control ports. Network Management connections are described in the Connecting a Network Printer to the BPX Switch section.

Note When a node is powered up, it enters "boot mode" which contains a default speed of 9600 bps. If the node control port was previously configured to 19,200, the first messages 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, the speeds match and the terminal display is readable.

Powering Up the Control Terminal

After the node receives power and correctly starts up, the following terminal screen appears:

gamma TRM YourID:1 IGX 8420 9.2 Aug. 15 1998 13:47 CST

Enter User ID:

If the screen is blank or does not display the initial screen, check all connections to the node, and ensure that the terminal and node are receiving power. If the connections are correct, press Delete a few times or cycle the terminal power.

Connecting a Network Printer to the BPX Switch

In most systems, the network printer is connected to a serial port on the Cisco WAN Manager NMS terminal server. The maintenance log and all statistics data reside on the Cisco WAN Manager. For more information about specifications, refer to the Cisco WAN Manager User's Guide.

However, it is possible to connect a printer to a node and use various BPX switch software print commands to print locally. This is helpful during the initial network installation phase.

Auxiliary Port Parameters for Okidata 184 Local Printer

The optional local maintenance printer for the BPX switch is the Okidata Model 184 dot matrix printer. You may connect the printer to any node.

The printer configuration requirements are described in Table 15-2 and Table 15-3.

Connecting Dial-In and Dial-Out Modems

Cisco Customer Service uses modems to remotely diagnose and correct customer problems with installed BPX switches. You can connect to a modem to each BPX switch to provide remote access.

The modem currently recommended for use with the BPX switch is the Codex Model V.34R. You must use an auto-answer modem.

A dial-in connection to a BPX switch RS-232 from Cisco Customer Service through a modem uses the control port of the BPX switch. This port is bidirectional transmit and receive.

A dial-out connection from a BPX switch through a modem to Cisco Customer Service uses the auxiliary port of the BPX switch.

The modems connect to a standard telephone line wall jack. The modem connections require special cables and setup procedures.

If the BPX switch is equipped with redundant BCCs, you must use a RS-232 Y-cable for the connections.

The modem interface requirements are described in Table 15-6.

Motorola V.34R BPX Switch Dial-In Configuration

This section describes how to configure auto-answer mode for both the V.34R modem and the BPX switch.

Enabling BPX Switch Auto-Answer (Dial-In to BPX switch)

To allow Cisco Customer Service to dial into your BPX switch to provide support and troubleshooting, use the following procedure:

Step 1 Use the cnfterm command to configure the BPX control port as follows:

Next Command: cnfterm {a|c}[baud rate][data bits][stop bits][output flow control{x|n}][input flow control{x|n}][CTS flow{x|n}][DTR{y|n}]

For parameter definitions that are used for the cnfterm command, refer to the Cisco WAN Switching Command Reference, Release 9.3.30.

Step 2 Set the BPX control port speed to 9600 bps.

Step 3 Use the cnftermfunc command to configure the Control port as follows:

Next Command: cnftermfunc {a|c}[index]

For parameter definitions that are used for the cnftermfunc command, refer to the Cisco WAN Switching Command Reference, Release 9.3.30.

Step 4 Enter c to select the control port.

Step 5 Enter 1 as the index parameter for the terminal type to VT100/Cisco StrataView.

Step 6 To program the modem, temporarily attach a terminal to the modem using a straight through RS-232 cable (DTE to DCE). The modem EIA port will automatically match the 9600 bps setting of the terminal.

Step 7 To set up the modem for proper operation for the V.34R to auto-answer mode, for example, dial-in to BPX, enter the following commands:

Note Consult the manual supplied with your modem for specifics concerning the modem configuration. Contact Cisco Customer Service for the latest modem configuration information.

Figure 15-6 Dial Modem Cabling for Auto Dial (dial-out to customer service)

Making External Clock Connections

If you want to synchronize the BPX switch to some other external equipment or a local digital central office, you can use one of two connectors on an BCC15-BC or BPX-BCC-3-BC back card shown in Figure 15-7 to accept a clock input.

You can use a DB15 connector labeled EXT TMG to connect a balanced T1 or E1 signal, which is synchronized from some higher-level source to the BPX switch. If an unbalanced 75-ohm E1 signal is available as the timing source, a BNC EXT TMG connector is also provided.

For a BCC-3-BC back card (back card for BCC-3-32M, BCC-3-64M, or BCC-4V), you can use a DB15 connector labeled EXT 1 TMG to connect a balanced T1 or E1 signal, which is synchronized from some higher-level source to the BPX switch.

The EXT 2 TMG connector provides a redundant connector to EXT 1 TMG. A T1 source with 100 ohm impedance or an E1 source with 100/120 ohm impedance typically uses this connector. If an unbalanced 75-ohm E1 signal is available as the timing source, a BNC EXT TMG connector is also provided.

The BPX switch can use these inputs rather than its internal Stratum 3 clock source.

Note Contact Cisco Customer Service for information on setting up either a 75-ohm or 120-ohm clock interface on the BCC back card.
