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,
see the section titled “Voltage Check (Additional Procedure)” (page 50).”
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.
See Figure 32 (page 46) for voltage reference points when performing the following measurements.
Figure 32 Voltage Reference Points for IEC 320 C19 Plug
IMPORTANT: Perform these measurements for every power cord that plugs into the server.
