Specifications
This section contains specifications for the Eserver pSeries 650 system.
pSeries 650 Physical Specifications and Loads
The following tables illustrate the physical, electrical and thermal, acoustical, and environmental
characteristics of various pSeries 650 system configurations.
Power and Electrical Requirements
Redundant power line cords are standard on the pSeries 650. The system uses dual ac power cords. For
maximum availability, each of the power cords should be fed from independent power grids to ensure that
there is no single point of failure.
Checking the Facility Outlets and Power Source
CAUTION:
Do not touch the receptacle or the receptacle faceplate with anything other than your test probes
before you have met the requirements in step 8.

Performing the following will ensure that appropriate power will be used by the pSeries 650. The following
checklist is for reference purposes, and will likely be performed by a service engineer prior to installation.
__ 1. The pSeries 650 is equipped to use 200-240 V ac. Check that the correct power source is
available.
__ 2. Before system installation, locate and turn off the branch circuit CB (circuit breaker). Attach tag
S229-0237, which reads "Do Not Operate."
Note: All measurements are made with the receptacle faceplate in the normally installed position.
__ 3. Some receptacles are enclosed in metal housings. On receptacles of this type, perform the
following steps:
a. Check for less than 1 volt from the receptacle case to any grounded metal structure in the
building, such as a raised-floor metal structure, water pipe, building steel, or similar structure.
b. Check for less than 1 volt from receptacle ground pin to a grounded point in the building.
Note: If the receptacle case or faceplate is painted, be sure the probe tip penetrates the paint and
makes good electrical contact with the metal.
__ 4. Check the resistance from the ground pin of the receptacle to the receptacle case. Check
resistance from the ground pin to building ground. The reading should be less than 1.0 ohm, which
indicates the presence of a continuous grounding conductor.
__ 5. If any of the checks made in substeps 2 and 3 are not correct, remove the power from the branch
circuit and make the wiring corrections; then check the receptacle again.
Note: Do not use the digital multimeter to measure grounding resistance.
__ 6. Check for infinite resistance between the phase pins. This is a check for a wiring short.
CAUTION:
If the reading is other than infinity, do not proceed! Have the customer make necessary
wiring connections before continuing. Do not turn on the branch circuit CB until all the
above steps are satisfactorily completed.
