LINK/ACT LEDs (For slide-in slots on the rear panel)
The slide-in slot has a LINK/ACT LED itself. When one slide-in module is well
installed and functioning, the relevant one lights green.
LINK LED ("STACK" port)
The LED lights green, when a management stack is made via the "STACK" port
and negotiates with associated devices successfully.
HUB ID Rotary Switch
All members of the management stack are ranked according to their "HUB ID"(Device
ID). There are eight degrees (0~7) in the rotary switch. The smaller number, the higher
degree. Device with smallest "HUB ID" will be the "Master" device. Then, system
management can perform by the way of the "Master Device".
Attention Every device in the management stack should have a unique
"HUB ID". In the meanwhile, a "HUB ID" which has been
using by a device, reused by another, the management stack
will fail.
RESET Button
The system will reboot when "RESET" button is pressed.
