The NB-30 Bridge Chassis View

Front Panel Information

The areas surrounding the main port display area provide the following device information:

IP

The Internet Protocol address assigned to the NB-30 appears in the title bar of the Chassis View window; this will display the IP address you have used to create the NB-30 icon. IP addresses are assigned via Local Management.

Connection Status

This color-coded area indicates the current state of communication between

SPECTRUM Element Manager and the NB-30 bridge.

¥Green indicates the NB-30 bridge is responding to device polls (valid connection).

¥Magenta indicates that the NB-30 bridge is reconÞguring because of a change in the Spanning Tree; note that board and port menus are inactive during this stand-by state.

¥Blue indicates an unknown contact status Ñ polling has not yet been established with the NB-30 bridge.

¥Red indicates the NB-30 bridge is not responding to device polls (device is off line, or device polling has failed across the network for some other reason).

Up Time

The amount of time, in a day(s) hh:mm:ss format, that the NB-30 bridge has been running since the last start-up.

Port Status

Displays the port status currently in effect. Management for the NB-30 supports one port display, therefore this Þeld will state Default.

MAC

The physical layer address assigned to the port through which SPECTRUM Element Manager is communicating with the NB-30 bridge. MAC addresses are hard-coded in the device, and are not conÞgurable.

Boot Prom

The revision of BOOT PROM installed in the device. This Þeld will not be available for the NB-30 bridge.

Firmware

The revision of device Þrmware stored in the NB-30 bridgeÕs FLASH PROMs.

Time

The current time, in a 24-hour hh:mm:ss format, set in the NB-30 bridgeÕs internal clock.
