Clear-Com HX System Frames - Manual (Page 59)

Note:
The dot matrix lights will also display system information when the ENG button
is pressed on the master CPU card. This is described below in the section on
the ENG button.
D
Status lights
OK Light
When flashing green , the OK light indicates that the CPU card is successfully
communicating with the EHX configuration software.
IPC (Interprocessor Communication) Light
The Interprocessor Communication (IPC) light only operates when there are
two CPU cards in the matrix. When lit
green , the light indicates that the two
CPU cards are exchanging information.
Master Light
An Eclipse HX-Delta system can have two CPU cards, although the system
will operate with only one. If the primary card becomes unavailable for any
reason, the second card can serve as backup while the primary card is
repaired or replaced.
The master light is lit green on whichever CPU card is currently serving as
master. If there is a backup CPU card in the matrix, its “master” light will not
illuminate if the primary card is acting as master.
LAN A Light
When a local area network (LAN) is connected to the matrix’s LAN A port, the
CPU card’s LAN A LED is lit
green to indicate a connection to the Eclipse
Configuration Software LAN A port.
LAN B Light
When a second local area network is connected to the matrix’s “LAN B” port,
the CPU card’s LAN B LED is lit
green to indicate a connection to the Eclipse
Configuration Software (EHX) LAN B port.
Sync Light
When multiple Eclipse HX matrices are connected together the Sync light is lit
green to indicate that the matrices are connected and synchronized.
SI Light
The SI light flashes green to indicate communications activity.
