Figure 3-6. Stacking Configuration and Identification Panel
Each stack device has a unique identifying unit ID that defines the unit’s position and function in
the stack. If the device is a stand-alone unit, the Stack LED is not illuminated. The default setting
is stand-alone.
The unit ID is manually configured by using the Stack ID button. The unit ID is indicated by the
Stack ID LEDs. Unit ID 1 and 2 are reserved for the Master and Backup Master unit, and
unit ID 3 to 6 are for Member units.
Unit ID Selection Process
The unit ID selection process is as follows:
1
Ensure that the stand-alone/Master device Console port is connected to a VT100 terminal
device or VT100 terminal emulator via the RS-232 crossover cable.
2
Locate an AC power receptacle.
3
Deactivate the AC power receptacle.
4
Connect the device to the AC receptacle.
5
Activate the AC power receptacle.
When powering up, the configured LED number (corresponding to the previously saved unit ID)
begins to flash. The LED flashes for 15 seconds. During this period, select a specific Stack ID
by pressing the Stack ID button until the appropriate Stack ID LED is illuminated.
