System information
The Power button toggles the system on and off.
See "About the Power button LED states"
on page 18.
The drive activity LED on the front panel indicates
drive activity from the on-board hard disk controllers.
The System ID button toggles the integrated ID LED
and the blue server board LED on and off.
The system ID LED identifies the system for
maintenance when it is racked with similar server
systems.
The front control panel includes four activity LED
indicators for each on-board network interface
controller (NIC).
NIC-1 represents network interface controller 1
■
NIC-2 represents network interface controller 2
■
NIC-3 represents network interface controller 3
■
NIC-4 represents network interface controller 4
■
When network links are detected on the controllers,
the LEDs are activated and remain on. The LEDs
blink when network activity occurs, and the rate at
which they blink is determined by the amount of
network activity that occurs.
When it is depressed, the NMI button puts the
appliance in a halt state, issues a non-maskable
interrupt (NMI), and then triggers the non-maskable
interrupt. When the NMI is triggered, the data that is
in the process of being written to the server may be
lost.
Veritas recommends that you do not enable NMI by
pressing the NMI button.
When depressed, the System Cold Reset button
re-boots and re-initializes the appliance.
