Cabling and Power Up

After the system has been unpacked and moved into position, it must be connected to a source
of AC power. The AC power must be checked for the proper voltage before the system is powered
up. This chapter describes these activities.

Checking the Voltage

This section provides voltage check information for use on the customer site. The empahsis
focuses on measuring the voltages at the power cord plug and specified as an IEC 320 C19 type
plug. This end plugs directly into the back of the server chassis.
NOTE:
Perform these procedures for each power cord that will be plugged directly into the
back of the server. If you do not obtain the expected results from this procedure during the
voltage check, refer to the section titled

Preface

The server requires a minimum of 2 power cords. To enable full power redundancy, 4 power
cords may be used. When using 4 power cords, dual power sources may be used to provide
additional power source protection.
Power cords are designated and labeled A0, A1, B0 and B1. Cords A0 and B0 should be energized
from the same power source and cords A1 and B1 should be energized from a second,
independently qualified power surce. The cord labeling corresponds to the labeling at the servers
power receptacles.

Voltage Range Verification of Receptacle

Use this procedure to measure the voltage between L1 and L2, L1 to ground, and L2 to ground.
Refer to Figure 3-21
