shown in Figure 2 on page 3. This ensures maximum airflow through the PSU and
minimizes noise.
Chapter 2. Features 9
Figure 10. Cooling fan
Airflow is front to rear with cooling air being drawn across the drives, through the
fans and pressurizing the rear of the enclosure. The pressurized rear allows the
PSU to draw the air that it requires; perforations at the rear of the chassis allow
cooling air to flow over the processor heatsinks, server board and PCI cards.
The cooling system must be operated with low-pressure rear exhaust installation
(back pressure created by rack doors and obstacles not to exceed 5 pascals [0.5mm
Water gauge]).
The cooling system provides sufficient capacity to ensure that drive maximum
temperatures have not exceeded at 35°C (95°F) with one failing fan at sea level.
The cooling cage contains ten individual high-speed single-rotor axial fans,
individually connected to and interfacing with the enclosure management PCB.
This interface provides power and speed control to the fans and returns speed
output from each fan to the management system.
Drive carrier module
The drive carrier module consists of a hard disk mounted in a drive carrier. Each
drive bay can house a single low-profile 2.54-cm (1.0-inch) high, 8.89-cm (3.5-inch)
form factor SATA disk drive in its drive carrier. The drive carrier has mounting
locations for SATA drives.
Each disk drive is enclosed in a sheet steel carrier which provides excellent thermal
conduction, radio frequency and electro-magnetic induction protection, as well as
affords the drive with maximum physical protection.
The front cap of the drive carrier supports an ergonomic handle, which provides
the following functions:
v Camming of drive carrier into and out of drive bays.
v Positive "spring loading" of the drive/backpane connector.

2. Check that the LEDs on all installed drive carrier modules are illuminated
(amber).
Note: Drive LEDs will not be lit during drive spin up.
3. Check that drive carrier modules have been correctly installed.
A green LED is always used for good or positive indication. A flashing
green/amber LED is used for non-critical conditions. With the exception of the
drive carrier module LED, which is lit amber under Normal conditions (see “Drive
carrier module faults” on page 30), a continuous red or amber LED indicates the
presence of a critical fault within the module.
Power supply units
The power supply unit provides a single external bi-color LED to indicate the
status of the power supply. When AC is applied to the PSU and standby voltages
are available, the LED will blink green. The LED will be solid on green to indicate
that all power outputs are available. The LED will be on solid amber to indicate
that the power supply has failed (shut down due to over current, shut down due
to over temperature, or a predictive failure).

3. Reduce the ambient temperature
Thermal cooling
The Secure Managed Client (SMC) - Storage Array uses extensive thermal
monitoring to ensure component temperatures are kept low and acoustic noise is
minimized. Airflow is from front to rear of the enclosure.
Table 15. Thermal cooling
Symptom Cause Action
If the ambient air is cool
(below 25°C or 77°F) and the
fans are observed to increase
in speed then some restriction
on airflow may be causing an
additional internal temperature
rise.
Note: This is not a fault condition.
The first stage in the thermal
control process is for the fans
to automatically increase in
speed when a thermal threshold
is reached. This may be caused
by higher ambient temperatures
in the local environment and may
be perfectly normal.
Note: This threshold changes
according to the number of drives
and power supplies installed.
1. Check the installation for any
airflow restrictions at either the
front or rear of the enclosure. A
minimum gap of 2.5 cm (1 inch)
at the front and 5 cm (2 inches) at
the rear is recommended.
2. Check for restrictions due to dust
build up; clean as appropriate.
3. Check for excessive re-circulation
of heated air from rear to front.
Use in a fully enclosed rack
installation is not recommended.
4. Check that all blank modules are
in place.
5. Reduce the ambient temperature.

1. Check to ensure that local
ambient environment temperature
is below the upper 35°C (95°F)
specification.
2. Check the installation for any
airflow restrictions at either the
front or rear of the enclosure. A
minimum gap of 2.5 cm (1 inch)
at the front and 5 cm (2 inches)
mm at the rear is recommended.
3. Check for restrictions due to dust
build up; clean as appropriate.
4. Check for excessive re-circulation
of heated air from rear to front.
Use in a fully enclosed rack

5. If possible, turn off the enclosure
and investigate the problem
before continuing.
Drive carrier module faults
Each Drive Carrier module has two LEDs: an upper (green) LED and a lower
(amber) LED.
v Under normal operation, the green LED is on and will flicker as the drive
operates
v Under normal operation, the amber LED will be:
– Off if there is no drive present
– Off as the drive operates
– On if a drive fault is present
Dealing with hardware faults
Ensure that you have obtained a replacement module of the same type before
removing any faulty module.
v If the subsystem is powered up and you remove any module, replace it
immediately. If the subsystem is used with modules or module blanks missing
for more than a few minutes, the enclosure can overheat, causing power failure
and data loss. Such use will invalidate the warranty.
v Replace a faulty drive with a drive of the same type and equal or greater
capacity.
v Refer to your vendor-supplied documentation when using storage software for
handling drive-related hardware faults.
v All drive bays must be installed with a drive carrier module in order to
maintain a balanced airflow.
v All the supplied plug-in power supply units, electronics modules and blank
modules must be in place for the air to flow correctly around the cabinet

CAUTION:
Observe all conventional ESD precautions when handling modules and
components. Avoid contact with backplane components and module connectors,
etc.
The top cover of the enclosure covers a service area which should be
Note:
accessed only by qualified service personnel. When the cover is replaced it
must be secured by turning the lock mechanism to the locked position.
Continuous operation during replacement
Depending on how the enclosure system is set up, if a disk unit fails, it can
normally be replaced without interrupting the use of the system.
