4. Lamp Indications
Lamp indications for this circuit card are shown in the table below.
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.
LAMP NAME COLOR STATE
OPE Green 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.
ST0~ST7 Green
The meanings of the ST0~ST7 lamps vary depending on the SEL switch settings as
shown in the table below.
SEL SWITCH MEANINGS
0
Lights when the receiving pair cable polarity of the TPn-X port is
reversed. (n = 0~7)
Note 1
2
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)
3
Lights when the TPn-X port is normal.
Remains off when collisions have occurred at the TPn-X port.
(n = 0~7)
