22 About Your SystemKVM ModulesYour system includes one of the KVM modules described in this section:• Avocent Analog KVM switch module (standard)• Avocent Digital Access KVM switch module (optional)NOTE: Earlier versions of KVM modules are not supported on your system.Avocent Analog KVM Switch ModuleThe Avocent Analog KVM switch module provides a custom connection for a keyboard, video (monitor),and mouse to monitor a server module. (You must use the custom cable provided with your system toconnect the KVM to the external devices.)NOTE: Your system has two custom cables—one that connects to the front of the server module to connect twoUSB devices and video, and a second cable that connects to the KVM to provide two PS/2 connections and a videoconnection. The cables are not interchangeable. It is recommended that you keep these custom cables available.The switch module also provides an Analog Console Interface (ACI) port, which allows you to connect aserver module via Cat5 cabling to an external device such as the Dell 2161DS Digital console switch orDell 180AS/2160AS analog console switches, without the need for a Server Interface Pod (SIP.)NOTE: Although the ACI port is an RJ-45 connector and uses Cat5 cabling, it is not an Ethernet network interfaceport. It is only used for connection to external KVM switches with Analog Rack Interface (ARI) ports.NOTE: The ACI port can only be used to connect to ARI ports on Dell console switches. To connect to other types orbrands of switches, including Avocent switches, you must connect to the switch’s PS2 and video ports using theproprietary dongle provided with that switch.Fan 2 fault indicator Off Fan 2 is operating normally.Amber Fan 2 has failed.
