Notes:
1. The illustrations in this document might differ slightly from your hardware.
2. An amber LED illuminates when a system error or event has occurred. To
identify the error or event, check the LEDs on the information panel of the
switch module.
OK (power-on): This green LED is located above the four external
10/100/1000 Mbps ports on the information panel. When this LED is on, it
indicates that the switch module has passed the power-on self-test (POST) and
is operational.
! (Ethernet switch error): This amber LED is located next to the OK (power-on)
LED on the information panel. This LED indicates that the switch module has
a fault. If the switch module fails the POST, this fault LED will be lit.
Ethernet link: This green link status LED is located at the top of each external
10/100/1000 Mbps port. When this LED is lit on a port, it indicates that there
is a connection (or link) to a device on that port.
