HP A7540-96010 manual Ethernet port, Heartbeat LED green, System Fault LED solid amber

Introduction

Heartbeat LED (green)

The Heartbeat LED indicates the status of the internal switch processor and the results of the Power On Self Test (POST).

Following a normal power-up, the Heartbeat LED blinks about once per second to indicate that the switch passed the POST and that the internal switch processor is running. In maintenance mode, the Heartbeat LED illuminates continuously. The Heartbeat LED also shows a blink code for POST errors and the over temperature condition. See “Heartbeat LED blink patterns” on page 42 for more information.

System Fault LED (solid amber)

The System Fault LED illuminates to indicate an over temperature condition or a POST error and the Heartbeat LED shows a blink code that defines the condition. See “Heartbeat LED blink patterns” on page 42 for more information.

Ethernet port

The Ethernet port (Figure 3) is an RJ-45 connector that provides a connection to a management workstation through a 10/100 Base-T Ethernet cable. The workstation can be a Windows® or a Linux® workstation that is used for advanced configuration and management tasks. You can manage the switch over the Ethernet connection using Switch Manager, the Command Line Interface (CLI), or SNMP. The switch through which the fabric is managed is called the fabric management switch.

The Ethernet port has two LEDs that provide activity and status information. (Figure 3)

■The Activity LED illuminates when data is being transmitted or received.

■The Link Status LED illuminates continuously when an Ethernet connection has been established.
