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.
Figure 3: Ethernet port and LEDs
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.
