QS1200 and QS2400 Systems
This chapter provides specifications for the QS1200 and QS2400 systems.
QS1200 and QS2400 Base System Components
The QS1200 and QS2400 base systems use high-density SAS 2.0 (6-Gb/s) drive enclosure available in a
rack-mount model. The QS1200 system has a capacity of twelve 3.5-in. SAS drives. The QS2400
system has a capacity of twenty-four 2.5-in. SAS drives.
The QS1200 and QS2400 base systems and expansion units provide high-capacity disk storage for
Fibre Channel, Infiniband, SAS and iSCSI environments, depending on the choice of the host interface
card.

1. Maximum weight indicates a base system/expansion unit with all of its drives and other components installed.
Because drive weights can vary greatly, this value can vary from the value specified as much as either 0.3 kg
(0.66 lb) times the maximum number of drives per controller-drive tray for 3.5-in. SAS drives or 0.08 kg (0.18
lb) times the maximum number of drives per base system/expansion unit for 2.5-in. SAS drives.

QS1200/QS2400 Base System Site Wiring and Power
This section provides site wiring and power information for the QS1200 and QS2400 base systems.
Site Wiring
The QS1200 and QS2400 base systems use wide-ranging, redundant power supplies that
automatically accommodate voltages to the AC power source. The power supplies meet standard
voltage requirements for both North American (USA and Canada) operation and worldwide (except
USA and Canada) operation. The power supplies use standard industrial wiring with line-to-neutral or
line-to-line power connections.
Keep this information in mind when you prepare the installation site for the QS1200 and QS2400
base systems:
•Protective ground – Site wiring must include a protective ground connection to the AC power
source.
NOTE: Protective ground is also known as safety ground or chassis ground.
•Circuit overloading – Power circuits and associated circuit breakers must provide enough power
and overload protection.
NOTE: To prevent damage to the base system, isolate its power source from large switching loads,
such as air-conditioning motors, elevator motors, and factory loads.
•Power interruptions – The base system can withstand these applied voltage interruptions:
• Input transient – 50 percent of the nominal voltage
• Duration – One half-cycle
• Frequency – Once every 10 seconds
•Power failures – If a total power failure occurs, the base system automatically performs a
power-on recovery sequence without operator intervention.

AC Power Input
Tab l e 9 provides the AC power input for the QS1200 and QS2400 base systems.
NOTE: Each power supply contains one 10-A slow-blow fuse.
Power Factor Correction
Power factor correction is applied within the power supply, which maintains the power factor of the
QS1200 and QS2400 base systems at greater than 0.95 with nominal input voltage.
AC Power Cords and Receptacles
Each QS1200 and QS2400 base system ships with two AC power cords, which use the standard AC
outlets in the destination country. Each AC power cord connects one of the power supplies in the
drive tray to an independent, external AC power source, such as a wall receptacle, or to any
uninterruptible power supply (UPS).
If you have a cabinet with internal power cabling, such as a ladder cord, you do not need the AC
power cords that are shipped with the QS1200 and QS2400 base system.
