2.9Power specifications
The drive receives DC power (+5V) through the interface connector.
2.9.1Power consumption
Power requiremen ts for the dr i ves are lis ted in the ta bl e on p age 8 . Typical power measurements are based on
an average of drives tested, under nominal conditions, using 5.0V input voltage at 25°C ambient temperature.
• Spinup power
Spinup power is measured from the time of power-on to the time that the drive spindle re aches operating speed.
• Seek mode
During seek mod e, the read /write actuator arm move s toward a spe cific positi on on the d isc surface and does
not execute a read or write operati on. Servo ele ctronics ar e acti ve. Seek mode power is mea sure d based on
three random seek operations every 100 msecs. This mode is not typical.
• Read/write power and current
Read/write power is measured with the heads on track, based on three 63 sector read or write operations
every 100 msecs.
• Idle mode power*
Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in
a random track location.
• Standby mode
During Standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/
write electronics are in power-down model
*During periods of drive i dle, some offl ine activity may occur acc ording to the S. M.A.R.T. speci fica tion, which may i ncrease acoust ic and

2.9.2Conducted noise
Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on
the +5 volt line.
Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave
injected noise at up to 10 MHz.

2.9.4Powe r- manag eme nt modes
The drive provides programmable power management to provide greater energy efficiency. In most systems,
you can control power management through the system setup program. The drive features the following
power-management modes:
The drive is in Active mode during the read/write and seek operations.
• Idle mode
The buffer remains enabled, and the drive accepts all commands and returns to Active mode any time disc
access is necessary.
• Standby mode
The drive enters Standby mode when the host sends a Standby Immediat e c omma nd. If the ho st has set the
standby timer, the drive can also enter Standby mode automatically after the drive has been inactive for a
specifiable length of time. The standby tim er delay is established using a Standby or Idle command. In Sta ndby
mode, thedrive buffer is enabled, the heads are parked and the spindle is at rest. The drive accepts all
commands and returns to Active mode any time disc access is necessary.
• Sleep mode
The drive enter s S leep m ode after rece iv ing a Slee p com man d fro m th e ho st. In Sl eep mod e, th e dr ive buffer
is disabled, the heads are parked and the spindle is at rest. The drive leaves Sleep mode after it receives a
Hard Reset or So ft Reset from the host. After re ceiving a reset , the drive exi ts Sleep mode and en ters Standby
mode with all current translation parameters intact.
• Idle and Standby timers
Each time the drive performs an Active function (read, write or seek), the standby timer is reinitialized and
begins counting down from its specified dela y times to zero. If the standby tim er reaches zero bef ore any drive
activity is required, the drive makes a transition to Standby mode. In both Idle and Standby mode, the drive
accepts all commands and returns to Active mode when disc access is necessary.

Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All measurements are consistent with ISO document 7779. Sound power measurements are taken under essentially
free-field conditions over a reflecting plane. For all tests, the drive is oriented with the cover facing upward.
Note.For seek mode tests, the drive is placed in seek mode only. The number of seeks per second is
defined by the following equation:
(Number of seeks per second = 0.4 / (average latency + average access time)

3.0Configuring and mounting the drive
This section contains the specifications and instructions for configuring and mounting the drive.
3.1Handling an d stati c discharge precautions
After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards. Observe the following standard handling and static-discharge precautions:
Caution:
• Keep the drive in the electrostatic discharge (ESD) bag until you are ready for installation to limit the drive’s
exposure to ESD.
• Before handling the drive, put on a grounded wrist strap, or ground yourself frequently by touching the metal
chassis of a computer that is plugg ed into a grounded outlet. Wear a grounded wrist strap through out the entire
installation procedure.
• Handle the drive only by its edges or frame.
• The drive is fragile—handle it with care. Do not press down on the drive top cover.
• Always rest the drive on a padded, antistatic surface until you mount it in the computer.
• Do not touch the connector pins or the printed circuit board.
• Do not remove the factory-installed labels from the drive or cover them with additional labels. Removal voids
the warranty. Some factory-installed labels contain information needed to service the drive. Other labels are
used to seal out dirt and contamination.
3.2Jumper settings
3.2.1Master/slave configuration
Use the options jumper block shown in Figure 3 to configure the drive for operation. This jumper block is the
4-pin header adjacent to pins 1 and 2 of the I/O signal pins. For additional information about using the Cable
select option, see Section 3.2.2.
The “Drive is master (or single drive)” option is the Dell default setting.

Momentus 5400.2 Dell Product Manual, Rev. B
3.2.2Cable-select option
Computers that use cable select determine the master and slave drives by selecting or deselecting pin 28,
CSEL, on the interface bus. Master and slave drives are determined by their physical position on the cable. To
enable cable select, set a jumper as shown in Figure 3. Refer to your computer manual to determine whether
your computer supports this option.
3.3Drive mounting
You can mount the drive using four screws in the side-mounting holes or four screws in the bottom-mounting
holes. See Figure 4 for drive mounting dimensions (dimensions in inches with mm in parentheses). Follow
these important mounting precautions when mounting the drive:
• Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling.
• Use only M3 x 0.5 mounting screws.
• Do not overtighten the mounting screws (maximum torque: 4.0 inch-lb).
• Four (4) threads (0.080 inches) minimum screw engagement recommended.
