Remains lit while this circuit card is in normal operation.

 

 

 

 

 

 

CRS0~CRS7

Green

 

Lights when the circuit card detects the carrier signal form the TPn-X port.

 

 

 

 

 

 

 

 

 

The meanings of the ST0~ST7 lamps vary depending on the SEL switch settings as

MEANINGS

 

 

 

 

 

 

 

 

 

 

0

Lights when the receiving pair cable polarity of the TPn-X port is

 

 

 

 

reversed. (n = 0~7) Note 1

 

 

 

 

 

 

ST0~ST7

Green

 

 

 

 

 

 

Lights when the 10 BASE-T (RJ-45) cable is attached to the TPn-X

port, and the TCP/IP link has been established. The lamp may light

 

 

 

 

 

regardless of the receiving pair cable polarity. (n = 0~7)

 

 

 

 

 

 

 

 

 

 

 

Lights when the TPn-X port is normal.

 

 

 

 

3

Remains off when collisions have occurred at the TPn-X port.

 

 

 

 

 

(n = 0~7) Note 2

 

 

 

 

 

 

 

 

 

 

 

 

 

Note 1: This lamp is used to indicate the status of the TPn-X port. Therefore, the circuit card operates normally regardless of the cable polarity.

Note 2: This circuit card can detect data packet collisions at a TPn-X port when it would be a collision of 2048 bit- times (2.048 ms) or when the packet collides 32 times consecutively. The port is then locked-out until the collision is over.
