Note Cisco-approved GBIC modules have a serial EEPROM that contains the module

serial number, the vendor name and ID, a unique security code, and cyclic

redundancy check (CRC). When a GBIC is inserted in the switch, the switch

software reads the EEPROM to check the serial number, vendor name and ID, and

recompute the security code and CRC. If the serial number, the vendor name or

ID, security code, or CRC is invalid, the switch places the interface in an

error-disabled state.

Note If you are using a non-Cisco approved GBIC module, remove the GBIC module

from the switch, and replace it with a Cisco-approved module.

For more information about GBICs, refer to the documentation included with

your GBIC.

LEDs

You can use the switch LEDs to monitor switch activity and its performance.

Figure 1-7 and Figure 1-8 show the Catalyst 3550-12T and 3550-12G LEDs and

the Mode button that you use to select one of the port modes. Figure 1-9,

Figure 1-10, and Figure 1-11

show the Catalyst 3550-24, 3550-24-DC, 3550-48,

and 3550-24-FX LEDs and the Mode button that you use to select one of the port

modes.

All of the LEDs described in this section except the utilization meter (UTIL) are

visible on the Cluster Management Suite (CMS) home page. The Catalyst 3550

Multilayer Switch Software Configuration Guide describes how to use CMS to

configure and monitor individual switches and switch clusters.
