Cabling the SRP I/O Module
Before powering up the router, you must set up a management console. The console enables you to communicate with your system during the power-up process and to manage your system using the command-line interface (CLI).
When connecting a console directly to the SRP I/O module, use a cable appropriate for your terminal connector. The cable must have a female DB-9 connector to attach to the RS-232 port on the SRP I/O module. See Figure 24 and Figure 25.
The console port is considered a data terminal equipment interface (DTE). Direct connection to a terminal or PC (which also have DTE interfaces) requires a crossover cable.
 | Note: The alarm function on the SRP I/O module is currently not implemented. |
Only ERX7xx and ERX14xx models have external timing ports and alarm leads located on the SRP I/O module. All ERX routers have console ports located on the SRP I/O module. See Table 7 for details on each component.
Table 7: SRP I/O Ports
Port | Description |
|---|---|
Alarm leads (ERX7xx and ERX14xx models only) | Six terminal blocks for external alarm contacts; use a minimum 26-AWG for each (currently not implemented) |
External timing ports (ERX7xx and ERX14xx models only) |
|
Management console ports |
|
External Timing Ports
| Note: This section applies to ERX7xx and ERX14xx models only. The ERX310 router does not support external timing. |
The SRP I/O module has two input ports for external clock sources. These ports provide a way to ensure that the router system clock remains synchronized with the network's system clock. The primary clock is labeled A; the secondary, redundant clock is labeled B.
Use the connectors appropriate for your locale (European or North American standard):
- European—Two 75-ohm E1 2.048-Mbps inputs with BNC connectors
- North American—Two 100-ohm T1 inputs with three
pin wire-wrap connectors. Pins are labeled T (tip), G (ground), and
R (ring). We recommend using 26-AWG wire minimum.
Note: Use shielded cables to connect the external clock sources to the clock source input ports.
Figure 24: SRP I/O Module for ERX14xx Models
To connect the clock source input ports:
- Depending on the connector type, complete one of the following
tasks:
- E1: Attach the BNC connector to Clock A's external timing port.
- T1: Wrap the tip wire on pin marked T of Clock A's external
timing port, the ground wire on G pin, and the ring wire on R pin.
Note: You can use a wire-wrap gun to attach wires to pins.
- Attach the opposite end of the external timing cable or wires to your network's clock source A.
- Repeat Steps 1 and 2 for the Clock B connections.
Management Ports
| Note: This section applies to all ERX routers. |
The Console section of the SRP I/O module has two ports for management access. (See Figure 24 and Figure 25.)
- The 10/100Base-T Ethernet port accepts an RJ-45 (male) connector, providing an out-of-band connection for LAN access through a Telnet session or SNMP.
- The RS-232 port accepts a DB-9 (female) connector for
direct CLI access from a console terminal.
The console port is considered a data terminal equipment interface (DTE). Direct connection to a terminal or PC (which also have DTE interfaces) requires a crossover cable.
Figure 25: SRP I/O Module for the ERX310 Router
See Accessing ERX Routers for more information about management access.
Connecting to the Network
To connect the router to the network:
- Insert an Ethernet cable (RJ-45) connector into the 10/100Base-T (RJ-45) port on the SRP I/O module until it clicks into place.
- Connect the other end of the cable to the appropriate Ethernet network for an out-of-band connection.
Connecting to a Console Terminal
When you connect a console directly to the router SRP I/O module, use a cable appropriate for your terminal connector. The cable must have a female DB-9 connector to attach to the RS-232 port on the SRP I/O module.
To connect the console to the SRP I/O module:
- Insert the female DB-9 connector into the RS-232 port,
and tighten the screws.
Caution: Do not overtighten the screws.
- Connect the other end of the cable to your terminal's serial port (VT100/ANSI).
