Cisco CATALYST 6509E 9 SLOT 15U CHASSIS NO POWER SUPPLY NO FAN TRAY Техническое Руководство

Observe the port status LED:

The LED turns green when the GBIC transceiver and the target device have an established link.

The LED turns amber while the GBIC discovers the network topology and searches for loops. 
This process takes about 30 seconds, and then the 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 that is installed in the target device. 

If you are using the LX/LH GBIC with MMF, you need to install a patch cord between the GBIC and the 
MMF cable. 

To connect to the supervisor engine uplink ports that use SFPs (Supervisor Engine 720 and Supervisor 
Engine 32), follow these steps (see 

):

We strongly recommend that you do not install or remove the SFP transceiver module with fiber-optic 
cables attached to it because of the potential damage to the cables, the cable connector, or the optical 
interfaces in the SFP transceiver. Disconnect all cables before removing or installing an SFP transceiver.

Removing and installing an SFP transceiver can shorten its useful life. Do not remove and insert SFP 
transceivers more often than is absolutely necessary.

The SFP transceiver modules are static sensitive devices. Always use an ESD wrist strap or similar 
individual grounding device when handling SFP transceivers or when coming in contact with modules.
