Eclipse Median Instruction Manual 2 - 7
STATUS LIGHTS
OK Light
When flashing, the “OK” light indicates that the CPU card is
successfully communicating with the Eclipse Configuration Software
(ECS).
IPC (Interprocessor Communication) Light
The “interprocessor communication” (IPC) light only operates when
there are two CPU cards in the matrix. When lit, the light indicates that
the two CPU cards are exchanging information.
Master Light
An Eclipse Median 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 illuminates 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 lights to indicate a connection to the
Eclipse matrix LAN A.
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 lights to indicate a connection to
the Eclipse matrix LAN B.
Sync Light
When you connect multiple Eclipse matrices together, the “sync” light
illuminates to indicate that the matrices are connected and
synchronized.
SI Light
The “SI” light flashes to indicate communications activity.
