Connect a Device to a Network for Out-of-Band Management

You can monitor and manage these devices by using a dedicated management channel. Each device has a management port to which you can connect an Ethernet cable with an RJ-45 connector. Use the management port to connect the device to the management device.

Ensure that you have an Ethernet cable that has an RJ-45 connector at either end. Figure 1 shows the RJ-45 connector of the Ethernet cable supplied with the device.

To connect a device to a network for out-of-band management (see Figure 2):

  1. Connect one end of the Ethernet cable to the management port (labeled MGMT or ETHERNET) on the device.
  2. Connect the other end of the Ethernet cable to the management device.

Connect a Device to a Management Console Using an RJ-45 Connector

You can configure and manage devices using a dedicated management channel. Each device has a console port which you can connect to using an Ethernet cable with an RJ-45 connector. Use the console port to connect the device to the console server or management console. The console port accepts a cable that has an RJ-45 connector.

Ensure that you have an Ethernet cable that has an RJ-45 connector at either end. One such cable and an RJ-45 to DB-9 serial port adapter are supplied with the device.

Figure 3 shows the RJ-45 connector of the Ethernet cable.

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 device, use a combination of the RJ-45 to DB-9 female adapter supplied with the device and a USB to DB-9 male adapter. You must provide the USB to DB-9 male adapter.

To connect the device to a management console (see Figure 4 and Figure 5):

  1. Connect one end of the Ethernet cable to the console port (labeled CON, CONSOLE, or CON1) on the device.
  2. Connect the other end of the Ethernet cable to the console server (see Figure 4) or management console (see Figure 5).
