Front panel LEDs

LEDs on the front panel of the G250 and G350 and their media modules give a quick overall understanding of the health of the system and subsystems. When alarms or problems occur, LEDs indicate that a technician’s attention is needed.

Automatic error detection

During normal operations, software or firmware automatically detects and attempts to fix or circumvent error conditions. Errors are detected in two ways:

●Firmware on a system component during ongoing operations

●A “periodic test” or a “scheduled test” started by software

A technician can run more comprehensive tests on demand.

SNMP

The G250/G350 reports alarms using SNMP traps. The G350 fully supports SNMP versions SNMPv1, SNMPv2c, and SNMPv3. The G250 supports SNMPv3 for sending SNMPv1, SNMPv2c, and SNMPv3 traps, but does not support the SNMPv1 trap mechanism.

Packet sniffing

The G250/G350 features packet sniffing. All packets, including non-Ethernet packets, that pass through the G250/G350, are recorded. The recorded packets are stored in a file that can be uploaded either to the S8xxx server or to a PC and read by Ethereal for troubleshooting purposes.
