Connecting to a Fiber-Optic SFP Module Port
3.
Insert the other cable end into a fiber-optic receptacle on a target device.
4.
Observe the port status LED:
—
The LED turns green when the switch and the target device have an established link.
—
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 a
problem with the adapter installed in the target device. See
for solutions to cabling
problems.
5.
If necessary, reconfigure and restart the switch or the target device.
Connecting to a 1000BASE-T SFP Module
To connect a CAT5 cable to a 1000BASE-T SFP module:
Caution:
To prevent ESD damage, follow standard board and component handling procedures.
1.
When connecting to servers, workstations, and routers, insert a four twisted-pair, straight-through cable in the
RJ-45 connector. When connecting to switches or repeaters, insert a four twisted-pair, crossover cable.
Note:
When connecting to a 1000BASE-T device, use a four twisted-pair CAT5 cable.
2.
Insert the other cable end in an RJ-45 connector on a target device.
3.
Observe the port status LED.
—
The LED turns green when the switch and the target device have an established link.
—
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.
