IBM BladeCenter Copper Pass-thru, Installation Manual

Page: 40 / 56

Notes:
1. The illustrations in this document might differ slightly from your hardware.
2. An amber LED is lit when an error or event has occurred. To identify the
error or event, check the other LEDs on the copper pass-thru module.
3.
An LED test occurs whenever the I/O module is turned on. All LEDs are
lit and remain lit for approximately 5 seconds and then return to a normal
state.
Power LED
This green LED is at the top of the I/O module on the front panel.
When this LED is lit, it indicates that the I/O module has passed the
POST and is operational.
Copper pass-thru module error LED (!)
This amber LED is at the top of the I/O module on the front panel.
This LED indicates that the I/O module has an error. If the I/O
module fails the POST, this error LED is lit.
LINK OK LEDs
There are fourteen green LINK OK LEDs on the right side of the LED
matrix on the front panel. Each of these LEDs indicates that there is a
valid connection to a device on that port channel and that both ends
of this connection are successfully communicating using compatible
network protocols. (See Chapter 4, “Completing the installation,” on
page 27 for information about supported networking environments.)
The LINK OK LEDs are arranged in a way that identifies each port
channel (LED columns A, B, C, D, and E) and the transceiver (LED
rows 1, 2, and 3) that is associated with it. If a LINK OK LED is not
lit, make sure that the blade server is in the correct slot and is
powered-on.
