The LED turns amber while the STP discovers the network topology and searches
for loops. This process takes about 30 seconds, and then the port LED turns green.
If the LED is off, the target device might not be turned on, there might be a cable
problem, or there might be problem with the adapter installed in the target device.
See Chapter 4, "Troubleshooting,"
If necessary, reconfigure and restart the switch or target device.
Follow these steps to connect a fiber-optic cable to a XENPAK module:
Do not remove the rubber plugs from the XENPAK module ports or the rubber
caps from the fiber-optic cable until you are ready to connect the cable. The plugs
and caps protect the XENPAK module ports and cables from contamination and
ambient light.
The 10-Gigabit Ethernet XENPAK modules are referred to as 10-Gigabit Ethernet
module ports in the switch software documentation.
Make sure that the XENPAK module is fully inserted into the module slot and that
the captive installation screws are fully tightened before attaching the fiber-optic
interface cable connector to the XENPAK module connector.
Remove the rubber plugs from the XENPAK module ports and fiber-optic cable,
and store them for future use.
Align the fiber-optic cable SC connector with the XENPAK module connector, so
that transmit (TX) on the cable meets receive (RX) on the XENPAK module
connector, and RX on the cable meets TX on the XENPAK module.
Insert the fiber-optic cable connector into the XENPAK module ports (see
Figure 3-48).
