Interpreting the LEDs
The OfficeConnect NIC has three light-emitting diodes
(LEDs) that can help indicate when there are problems
with your network connection.
See Figure 2 in Chapter 1 for a picture of the LEDs.
Table 4 explains the LED states.
If the LNK (10 LNK or 100 LNK) LED is off and the PC is
powered on and the network cable is connected, check
the following:
1 Ensure that the network hub or device to which the
NIC is connected and the cable connecting to your
NIC comply with the 10BASE-T or 100BASE-TX
specifications.
2 Ensure that the network hub or device to which the
NIC is connected is powered on.
