Step 4: Connect External Devices and Cables

• Connecting the JA2500 Appliance to a Management Console
• Connecting the JA2500 Appliance to the Network

Connecting the JA2500 Appliance to a Management Console

Every JA2500 appliance has a console port with an RJ-45 connector that you can use to connect the appliance to the management console or to a console server. An RJ-45 cable, as shown in Figure 9, and an RJ-45 to DB-9 serial port adapter are supplied with the appliance.

Figure 9: Ethernet Cable Connector

1. Connect the RJ-45 to DB-9 serial port adapter to the serial port of the management device (laptop or PC) that you will use to access the Junos Space CLI.

   Note: If your laptop or PC does not have a DB-9 male connector pin and you want to connect your laptop or PC directly to the appliance, use a combination of the RJ-45 to DB-9 female adapter supplied with the appliance and a USB to DB-9 male adapter. You must provide the USB to DB-9 male adapter.

2. Connect one end of the Ethernet cable into the console port (labeled CONSOLE) on the front panel of the appliance.
3. Connect the other end of the Ethernet cable into the RJ-45 to DB-9 serial port adapter.

Connecting the JA2500 Appliance to the Network

Though the JA2500 appliance has four Ethernet interfaces, only three, labeled 0 (eth0), 1 (eth1), and 3 (eth3), can be used; the other Ethernet interface, labeled 2, is reserved for future use. The eth0 Ethernet interface must be mandatorily connected to a network for managing the Junos Space Web client and devices. Connecting the eth1 interface to the network containing the Junos Space nodes and the eth3 interface to the device management network is optional.
For information about the Ethernet Interfaces in JA2500 appliance, see Junos Space Ethernet Interfaces Overview.

1. Plug one end of the Ethernet cable into the port labeled 0.
2. Plug the other end of the Ethernet cable into the network.

   Note: If you choose to connect the JA2500 appliance to both Ethernet interfaces, then you should plug the other end of the Ethernet cable into the network that contains the Web UI clients and the other Junos Space nodes in the fabric.

3. (Optional) If you are using eth1 Ethernet interface, take an Ethernet cable, plug one end of the Ethernet cable into the port labeled 1, and the other end into the network that contains the Junos Space nodes in the fabric.
4. (Optional) If you are using eth3 Ethernet interface, take an Ethernet cable, plug one end of the Ethernet cable into the port labeled 3, and the other end into the network that contains the devices being managed by Junos Space.
