ACKPLANE
The backplane will accommodate a total of four system groups through its 16 adapter slots. The
backplane slots are numbered 1 through 16, right to left, as viewed from the rear panel. The slots
are electrically connected in pairs of two: slots 1 and 2, slots 3 and 4, and so on. Therefore, the
backplane is configurable
in multiple groups of two slots each, resulting in configurations of 2, 4, 6 or
8 slots per group. The processor module should always be located in the first slot of the group.
In most installations, slot one will provide connections for the processor module for the first group,
and slot fifteen will provide connections for the EMS processor module. Note that slot 15 is always
used for the EMS when the EMS is present.

ONNECTORS
The Environmental Management System (EMS) manages all the intelligent sensors located
throughout the cluster of CSX7000s. In order to function, the EMS must properly connect to each
CSX7000 within the cluster.
The EMS connections consist of RJ-11 jacks located on the upper-left side of the back panel. The
EMS module itself is identified as IES Supervisor, and has an IN and OUT connection. To the left
of the IES Supervisor is the connection to the IES circuitry for the individual platform (subsystem).
These IN and OUT connections are in a vertical position, and are labelled IES. For more
information, refer to
EMS
and
Monitoring Systems
.
If multiple CSX7000s make up a cluster, IES connections are daisy-chained together. Refer to
CSX7000 Cabling
for further details.

The monitor connections (i.e., VIDEO) are located to the left of the back panel, and are labelled
VIDEO IN and VIDEO OUT. The VIDEO OUT connection of the first CSX7000 connects to the video
monitor, while the VIDEO IN connection connects to the VIDEO OUT of the second CSX7000 in the
cluster. This type of daisy-chain connection continues throughout the cluster. Refer to
CSX7000
Cabling
for further details.

UPPLY
To the far left of the back panel is a vertical column for the power supply bay. The bay houses dual
350 watt power supplies (PS1 and PS2), which provide fault tolerance in the event of a single power
supply failure. Each power outlet on the CSX7000 can be connected to a separate power source for
additional protection. Once the outlets are properly connected to an AC power source, the power
supplies may be controlled by the switches above the outlets.
