Management Ports

52
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 on page 51 and Figure 25 on page 52.)
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.

See "Accessing ERX Routers" on page 69 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
1.
the SRP I/O module until it clicks into place.
Connect the other end of the cable to the appropriate Ethernet network for an
2.
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.
