LED Colors and Their Meanings
Chapter 6148
HF2 Switch LEDs
The HF2 switch LED colors and meanings are explained below.
❏ For each “Status” LED on the switch:
✓ If the card/switch module is not operating, the LED is off.
— For the integrated Ethernet management LAN adapter card
(in the top slot) and the integrated 8-port fiber card (in the
middle slot): the card can be safely removed by qualified HP
personnel only.
— For an A6388A HF2 8-port fiber or A6389A HF2 4-port
copper switch module in the expansion slot (the bottom slot):
the switch module can be safely removed by you or qualified
HP personnel.
✓ If a fault is occurring on the card/switch module, the LED shows
as solid yellow.
✓ If the card/switch module passed the self-test and is operating,
the LED shows as solid green.
❏ For the “Power A” and “Power B” LEDs on the switch:
✓ If the power to the switch is off, the LEDs are off.
✓ If the power to the two redundant power buses is on, the LEDs
show as solid green.
Note that if only one of the “Power” LEDs shows as solid green,
the switch is still operational.
❏ For the “Ethernet Port Main” and “Ethernet Port Aux” LEDs on the
switch:
✓ If the associated Ethernet port is not connected to the Ethernet
network, the LED is off.
✓ If the connection from the associated Ethernet port to the
Ethernet network is operational, the LED shows as solid green.
✓ If data is flowing between the associated Ethernet port and the
Ethernet network, the LED shows as flashing green.
