LEDs
In addition to the OK and Gigabit Ethernet switch module error (fault) LEDs
on the information panel each external port on the Gigabit Ethernet switch
module has an Ethernet Tx/Rx LED. The following illustration shows the
LEDs on the Gigabit Ethernet switch module. A description of each LED
follows the illustration.

OK: This green LED is on the left side of the information panel, above the four
external 10/100/1000 Mbps connectors. When this LED is lit, it indicates that
the Gigabit Ethernet switch module has passed the power-on self-test (POST)
with no critical faults and is operational.
Gigabit Ethernet switch module error (fault): This amber LED is on the right
side of the information panel, above the four external 10/100/1000 Mbps
connectors. When this LED is lit, it indicates that the Gigabit Ethernet switch
module has a fault. If the Gigabit Ethernet switch module fails the POST or
detects an operational fault, this LED is lit.
Note:
When this LED is lit, the system-error LED on the BladeCenter unit is
also lit.
Ethernet link OK: This green link status LED is at the top of each external
10/100/1000 Mbps connector. When this LED is lit on a port, it indicates that
there is a connection (or link) to a device on that connector.
Ethernet Tx/Rx: This green activity LED is at the bottom of each external
10/100/1000 Mbps connector. When this LED flashes on a connector, it
indicates that data is being transmitted or received (that is, activity is
