Host Connections
This chapter contains configurations for one or two Sun StorEdge A3000 controller
modules connected to one or more hosts. It also contains information about
connecting power to an Ultra™ host system.
You can connect a controller module to an Ultra 2 host system; however, you must
connect the power cord of the Ultra 2 host to one of the AC power sequencers in the
expansion cabinet that contains the controller module.
You need to order one of the following power cords depending on the type of power
sequencer in the expansion cabinet (
■ Ultra™ Enterprise™ expansion cabinet and StorEdge expansion cabinet—
part number 530-2197-xx
■ 56-Inch Data Center expansion cabinet—part number 180-1189-xx (United States)
or part number 180-1190-xx NEMA (European)
Caution – Failure to connect the power cord correctly as described here may cause
excessive ground current that could damage the system.

1. Gain access to the AC power sequencers.
See the documentation that came with the expansion cabinet.
2. Route the power cable from the Ultra 2 host under the expansion cabinet frame on
the same side as the power sequencer.
3. Plug the power cord from the Ultra 2 host into the top power connector of either
power sequencer (
FIGURE 1-5).
The power connectors are located on the other side of the power sequencer from the
main switch.
4. Reassemble the expansion cabinet.

Key is 6. These error messages are information only and will not impact system
performance.

2.5.3Connecting to AC Power Source
Each of the AC power cords connected to the expansion cabinets should be on
independent circuit breakers.
To ensure proper redundancy, if independent circuit breaker boxes or AC power
sources are used, power cords from the same expansion cabinet should be connected
to different circuit breaker boxes or AC power sources.
Caution – You must ensure that the second rack will not lose power without the
first. Data loss is likely to occur if this happens. DO NOT configure the 3x15
expansion cabinets as shown in
