Notes:

The total rack power can be derived from the sum of the power that is used by the drawers in the rack.

For FC EPB8, each side can support a maximum of 600 amps (A) and 10 circuit breakers. The PDP can hold up
to twenty (ten per power source) circuit breakers with ratings between 5 A and 90 A. Each power source
supports up to 8.4 kVA.

For more information about FC 6117 and FC EPB8, see “Model 7014-T00 rack with optional DC power
distribution panel.”

Preliminary data is subject to change.

See your individual server or hardware specifications for temperature and humidity requirements.

Rack noise levels depend on the number and type of drawers installed. See your server or hardware
specifications for specific requirements.

Note:

All rack installations require careful site and facilities planning designed to both address the

cumulative drawer heat output and provide the airflow volume rates necessary to comply with drawer
temperature requirements. All rack installations require careful site and facilities planning designed to

Note:

Acoustic doors are available for IBM racks. Feature code 6248 is available for the 0551 and

7014-T00 racks. Feature code 6249 is available for the 0553 and 7014-T42 racks. The overall sound
reduction is approximately 6 dB. The doors add approximately 381 mm (15 in.) to the depth of the racks.

Racks can be heavy when populated with several drawers. Use the Weight distribution distances for
racks when loaded and Floor loading for racks when loaded tables to ensure proper floor loading and
weight distribution.

Model 7014-T00 rack with optional DC power distribution panel:

Hardware specifications provide detailed information for your rack, including dimensions, electrical,
power, temperature, environment, and service clearances.

Feature code (FC) 6117 (-48 V dc power distribution panel (PDP))

This feature provides a top-mounted, dual DC power distribution panel for a rack that can contain
varying quantities of central processing unit (CPU) drawers, storage subsystems, or both. Up to two DC
H80 systems or two DC M80 systems are supported, in addition to up to four DC storage subsystems.
This feature is built without attached power cables. It comes with a series of power connectors that is
built into its rear bulkhead. The appropriate DC power cables are included with supported drawer
systems and plug into the power connectors at the rear of the 6117 PDP.

FC EPB8 (-48 V dc power distribution panel (PDP))

This feature provides a top-mounted -48 V dc PDP for model 7014-T00 racks that can contain varying
quantities of drawers, storage subsystems, and OEM equipment. This feature is preinstalled on the
7014-T00 rack. The PDP sits on top of the rack and does not take up any EIA space. The PDP supports
redundant power with a split A and B side. Each side can support up to 10 circuit breakers that are rated
between 5 - 90 amperes with a maximum load of 600 amperes. FC EPB8 does not include circuit breakers
