B.3 LEDs
CPU LEDs
Normally the CPU status LED should blink consistently one second on, one second off.
If this is not the case, an error has been detected during the boot. The blink pattern can
be interpreted via the following table:
NOTE:
The Ethernet error mentioned in the above table will occur automatically if the Fast
Ethernet link is not connected to an external hub during the boot. If the Fast Ethernet is not
being used or is connected later, this error can be ignored.
Rear Panel LEDs
The ACS' rear panel has connectors (serial, console and Ethernet) with some LEDs that
have the following functionality:
Ethernet Connector
•
Col (collision)
- Shows collision on the LAN every time the unit tries to transmit
an Ethernet packet.
•
DT/LK (data transaction/link state)
- DT flashes when there's data transmitted to
or received from the LAN. It's hardware-controlled. LK keeps steady if the LAN
is active. The green LED is Data Transaction activity and the yellow one is LinK
state.
•
100
- If 100BT is detected the LED lights on. If 10BT is detected it turns off.
