CHAPTER 2 PRIMEPOWER650 Rack-mount Type (8U) Server
(3) Redundant PSU configuration (N+1) for 100 VAC power supply
This main unit can optionally support the redundant PSU configuration.
The following section describes the power cable connection for redundant PSU
configuration for a 100 VAC power supply (N+1).
l Number of power cables
The following cables (with parallel 2-pin plug with ground wire) are supplied with the
main unit or with the optional unit.
- Three power cables for 100 VAC power supply (supplied with the main unit)
- One power cable for connection to optional PSU for redundant configuration
(supplied with the optional unit)
Connect the main unit power cables to 100-120 VAC grounded outlets as shown in
Figure 2.9.
4If the main unit employs software for automatic power control and the mode
switch is set to UNLOCK or LOCK, plugging a power cable into an outlet may
automatically turn on the power. To prevent such an occurrence, set the mode
switch to MAINTENANCE before plugging the power cable into the outlet.
Note 1: The power cables are connected to the power supplies in the main unit on a
one-to-one correspondence. The main unit contains two power supplies in
the basic configuration. Installation of five or more CPUs requires a PSU
expansion unit. Three power cables, including one for a PSU expansion unit,
are supplied with the main unit. It is recommended that the power cable for a
PSU expansion unit be installed when the main unit is installed. If this has
been done, no additional power-related construction is required to install the
PSU expansion unit
Note 2: Each power cable must always be connected to a 100-120 VAC grounded outlet.
