Connecting the JCS 1200 Management Module to the Network

The management module supports network connection through an Ethernet connector or a serial connector (see Figure 1).

All management module network connections to Routing Engines are made through the CLI. You can perform initial configuration of the management module after you connect it to your network; however, because some requirements are imposed by the default management module settings, it might be easier to perform these setup operations through a direct connection.

For direct connection of a computer to the management module Ethernet connector, you need a Category 5 or higher Ethernet cable.

Network connections through the serial connector may require an Advanced Management Module (AMM) adapter.

See the JUNOS Protected System Domain Configuration Guide for information about accessing the management module CLI.

The following topics describe how to make typical network connections for a management module:

Connecting to the JCS 1200 Management Module Using a Network Ethernet Connection

To connect the management module to the network using the Ethernet port:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  2. Connect one end of an Ethernet cable to the Ethernet port on the management module. See Figure 1 for the location of input and output connectors on the management module.
  3. Connect the other end of the Ethernet cable to the network.
  4. Check the Ethernet LEDs to make sure that the network connection is working.
    • A lit green Ethernet LINK LED indicates that there is an active connection through the port to the network.
    • A flashing green Ethernet activity (TX/RX) LED indicates that there is activity through the port over the network link.

Connecting to the JCS 1200 Management Module Using a Direct Ethernet Connection

To connect the Ethernet cable directly to the management module:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  2. Connect one end of an Ethernet cable to the Ethernet port on the management module. See Figure 1 for the location of input and output connectors on the management module.
  3. Connect the other end of the Ethernet cable to the Ethernet port on the client computer.
  4. Check the Ethernet LEDs to make sure that the network connection is working.
    • A lit green Ethernet LINK LED indicates that there is an active connection through the port to the network.
    • A flashing green Ethernet activity (TX/RX) LED indicates that there is activity through the port over the network link.

Connecting to the JCS 1200 Management Module Using a Console Serial Connection

To connect the management module to a console using a serial cable:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  2. Plug one end of an RJ-45 serial cable into the serial connector on the management module. See Figure 1 for the location of input and output connectors on the management module.

    Note: Some consoles require that you use an AMM adapter. If needed, plug an AMM adapter into the serial connector on the management module, and then connect the serial cable. For information about the AMM adapter pinouts, see Pinouts for the RJ-45 Adapters.

  3. Connect the other end of the serial cable to your console.

    The serial cable must have the characteristics shown in Serial Cable Characteristics for the JCS 1200 Management Module.

Connecting to the JCS 1200 Management Module Using a Direct Serial Connection

To connect the management module to a client computer using a serial cable:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  2. Plug one end of an RJ-45 serial cable into the serial connector on the management module. See Figure 1 for the location of input and output connectors on the management module.

    Note: The serial cable must have the characteristics shown in Serial Cable Characteristics for the JCS 1200 Management Module.

  3. Connect the other end of the serial cable to the serial connector of the client computer, such as a notebook computer.
  4. Configure the serial port of the client computer to the following values:
    • Baud rate—57600
    • Parity—none
    • Stop bits—1
