Chapter SGE2000/SGE2000P Gigabit Ethernet Switch Reference Guide 2 Resetting the Unit to Factory Default Mode To reset the unit to the factory default settings, press the front panel RESET button (see Figure 3.) The unit is set to Stack mode with a Unit ID of 0. Understanding LED Indicators Each unit contains a Master LED indicator and eight unit LEDs. The LED status definitions are shown in the table below. LED Master Mode Solid Off ID n Solid Off All ports Solid Color Green N/A Green N/A Red Description The switch is the Stack Master.. The switch is not the Stack Master or the switch is not stacked. The switch is Unit ID n. The switch is not Unit ID n or the switch is not stacked. The switch is powered on, but not operational. Stack Troubleshooting and Maintenance Replacing a Failed Member Stack Unit in an Operational Stack If a unit that is not the Stack Master fails in an operational stack, the Stack Master discovers that the unit is no longer responding during the Master Discovery process. The Stack Master directs all other stack members to route unit-to-unit traffic around the failed unit using the ring topology of the stacking connections. Concurrently, the Stack Master notifies the system administrator of the failure by sending SYSLOG messages and SNMP traps. Because all traffic has been routed around the failed unit, when it is disconnected from the stack, the stack continues to run as long as all other stacking connections are left intact.
