Controller Overview

RJ-45 Console Port

The RJ-45 console port connection uses an RJ-45-to-DB-9 female cable.

Console port LED meanings:

•Off—The RJ-45 console is inactive (the USB console is active).

•Green—The RJ-45 console is active (the USB console is inactive).

10/100/1000 Ethernet Management Port

You can connect the controller to a host such as a Windows workstation or a terminal server through the 10/100/1000 Ethernet management port. The 10/100/1000 Ethernet management port is a VPN routing/forwarding (VRF) interface and uses an RJ-45 crossover or straight-through cable.

Management port LED meanings:

•Off—The link is down.

•Green—The link is up and there is no activity.

•Blinking green—The link is up and there is activity.

Controller’s System LEDs

If your controller is not working properly, check the LEDs on the front panel of the unit. You can use the LED indications to quickly assess the unit’s status.

To select or change a mode, press the Mode button until the desired mode is highlighted. When you change modes, the meanings of the LED colors also change.

Table 3 explains how to interpret the LED colors in different modes.

Note An amber LED could indicate an error or a possible hardware failure.
