Front Panel Indicators/Connections
The only indicators present on the HPS/RFL GARD Pro system front panel are 20 programmable
tri-colored LEDs and a green power ON light. The LEDs are normally factory set but can be
customized by the user. The main user interface is through an Ethernet port for connection to a
web-based server.
Shown below is a typical HPS/RFL GARD Pro system LED configuration for a 3U chassis. Note
that in most applications not all the LEDs are used. A 6U chassis has the same configuration
however the LEDs are orientated vertically.
