Chapter 1. General description

One country-specific wall power cord is also ordered separately and attaches to a UTG524-7
connector on the front of the PDU.
Supported power cords include features #6489, #6491, #6492, #6653, #6654, #6655, #6656,
#6657, #6658, and #6667. Two RJ45 ports on the front of the PDU enable the client to
monitor each receptacle’s electrical power usage and to remotely switch any receptacle on or
off. The PDU is shipped with a generic PDU password. IBM strongly urges clients to change it
upon installation.
Feature #EPTQ
This feature is an intelligent, switched 208 volt 3-phase ac PDU with twelve C13 receptacles
on the front of the PDU. The PDU is mounted on the rear of the rack, making the twelve C13
receptacles easily accessible. Each receptacle has a 20 amp circuit breaker. The PDU can be
mounted vertically in rack side pockets, or it can be mounted horizontally. If mounted
horizontally, it uses 1 EIA (1U) of rack space. See feature EPTH for horizontal mounting
hardware.
Device power cords with a C14 plug connect to C13 PDU receptacles and are ordered
separately. One wall power cord is provided with the PDU (no separate feature number) and
has an IEC60309 60A plug (3P+G). The PDU supports up to 48 amps. Two RJ45 ports on the
front of the PDU enable the client to monitor each receptacle’s electrical power usage and to
remotely switch any receptacle on or off. The PDU is shipped with a generic PDU password.
IBM strongly urges clients to change it upon installation.

1.10.7 Rack-mounting rules
Consider the following primary rules when you mount the system into a rack.
The system can be placed at any location in the rack. For rack stability, start filling a rack from
the bottom. Any remaining space in the rack can be used to install other systems or
peripheral devices, if the maximum permissible weight of the rack is not exceeded and the
installation rules for these devices are followed. Before placing the system into the service
position, be sure to follow the rack manufacturer’s safety instructions regarding rack stability.
Three to four service personnel are required to manually remove or insert a system unit into a
rack, depending on its dimensions, weight, and content. To avoid the need for this many
people to assemble at a client site for a service action, a lift tool can be useful. Similarly, if you
have chosen to install this customer setup (CSU) system, similar lifting considerations apply.
The Power E850C has a maximum weight of 69 kg (152 lbs). However, by temporarily
removing the power supplies, fans, and RAID assembly, the weight is easily reduced to 55 kg
(121 lbs).
When lowering the Power E850C onto its rails in the rack, the server must be tilted on one
end about 15 degrees so that the pins on the server enclosure fit onto the rails. This process
equates to lifting one end of the server about 4 cm (1.6 in.). This can be done using a tip plate
on a lift tool or manually adjusting the load on a lift tool or tilting during the manual lift.
Consider the optional feature #EB2Z Lift Tool.
Power cord: Ensure that the appropriate power cord feature is configured to support the
power being supplied.
