4: User Interfaces

The XLi features three user interfaces for controlling the XLi's functions:
• A keypad/display interface on the front panel of the XLi
• A command line interface, available through the serial and network ports
• A web interface, available from a browser connected to the XLi's network port.
There is also an Alarm Status LED on the front panel.

Card Positions

In the user interfaces, the card positions are referred to by Option Bay number (see Figure 6).

Alarm Status LED

The Alarm Status LED, located on the front panel, displays the alarm-state of the XLi unit. The LED has
four states:
Dark
= Power is off.
Green = No F73-related alarms. The current reference source input is locked.
Amber = No F73 Alarms. Time-out Delay is counting down, but hasn't elapsed. The current reference
source input is unlocked (e.g. broken antenna cable or no GPS signal)
Red = An indicator in F73 has triggered an alarm. Check F73 to find out what the fault/unlock condition
is and take appropriate action.
