About the Switch 4200 Series 15

Fiber GBIC's.

The default state for these ports is auto-negotiation enabled, where speed, duplex and flow control modes are negotiated. Because the speed and duplex modes are fixed by the media type, only the flow control is negotiated with the link partner. Alternatively, auto-negotiation can be disabled and the flow control setting can be manually configured.

1000BaseT GBIC's

These ports will auto-negotiate to 1000BASE-T, full duplex only. Although it is not possible to disable auto-negotiation it is possible to change the advertised capabilities for flow control support, effectively enabling or disabling flow control.

LEDs Table 4 lists LEDs visible on the front of the Switch, and how to read their status according to color. For information on using the LEDs for problem solving, see “Solving Problems Indicated by LEDs” on page 54.

It is not possible to determine the duplex mode from the LEDs. For more detailed information, refer to the “SuperStack 3 Switch Management Interface Reference Guide” on the CD-ROM that is supplied with the Switch.
