1.7. Power Supply Unit

AC-DC Power is provided by two dual-redundant power supply units with specific load capability, mechanical packaging and a power cage with output loom to suit this application.

A Power Supply Mounting Cage is fitted in the rear of the enclosure as part of the subsystem core product. The cage houses two individually hot pluggable 850W AC Power Supply Units (PSUs), each with its own IEC inlet connector and failure indicator.

PSU voltage operating ranges are nominally 100V - 240V AC, selected automatically. A typical PSU is shown in

Fig. 07

.

Each PSU incorporate an Audible Alarm to indicate when a fault state is present and a bi-color (Green/Red) LED which indicates the

PSU status.

1.7.1. Multiple Power Supply Units

The LaCie 12big Rack Network includes two PSUs fitted in the Power Supply Mounting Cage, providing dual power sources for the system so that if one PSU fails the other maintains the power supply and enclosure operation is not affected while you replace the faulty unit.

PSU replacement should only take a few minutes to perform but must be completed within 10 minutes from removal of the failed

PSU.

1.8. Cooling Fans

The Cooling Fans are high speed single rotor axial fans. Ten fans are housed in a Cooling Cage, located centrally within the enclo-

sure, between the drive bays and the Motherboard, as shown in Fig.

02

. This ensures maximum airflow through the PSU and minimizes noise.

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, and perforations at the rear of the chassis allow cooling airflow over the

Processor heatsinks, memory, motherboard 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 are not exceeded at 35°C ambient with one fan failed 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 tacho output from each fan

User Manual

2.8. Grounding Checks

The product must only be connected to a power source that has a safety electrical earth connection.

CAUTION: If more than one product is fitted in a rack, the earth connection to the rack is even more important, because the rack will then have a high “EARTH LEAKAGE CURRENT” (“TOUCH CUR-

RENT”).

The earth connection to the rack must be checked before switching on, by an electrical engineer who is qualified to the appropriate local and National standards to perform the check.

2.9. Data Security

✦ Power down your host computer and all attached peripheral devices before beginning installation.

✦ Each enclosure contains up to 12 removable disk drive modules. Disk units are fragile. Handle them with care, and keep them away from strong magnetic fields.

✦ All the supplied plug-in modules and blanking plates must be in place for the air to flow correctly around the enclosure and also to complete the internal circuitry.

✦ If the subsystem is used with modules or blanking plates missing for more than a few minutes, the enclosure can overheat, causing power failure and data loss. Such use may also invalidate the warranty.

✦ If you remove a drive module, replace it immediately. If it is faulty, replace it with a drive module of the same type and capacity.

✦ Ensure that all disk drives are removed from the enclosure before attempting to manhandle or move the rack installation.

✦ Do not abandon your backup routines. No system is completely foolproof.

4.5.4. Thermal Monitoring and Control

The LaCie 12big Rack Network enclosure uses extensive thermal monitoring and takes a number of actions to ensure component temperatures are kept low and also to minimize acoustic noise. Air flow is from front to rear of the enclosure.

Table 16 - Thermal Monitoring and Control

Symptom

If the ambient air is cool

(below 25 °C) and the fans are observed to increase in speed then some restriction on airflow may be causing additional internal temperature rise.

Note: This is not a fault condition.

Cause

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 fitted.

Action

1. Check the installation for any airflow restrictions at either the front or rear of the enclosure. A minimum gap of 25mm at the front and 50mm 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 the 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.

4.5.5. Thermal Alarm

2. An amber LED on one or more Power Supply Units.

If the internal temperature measured in the airflow through the enclosure exceeds a pre-set threshold a thermal alarm will sound.

Action

1. Check local ambient environment temperature is below the upper 35°C specification.

2. Check the installation for any airflow restrictions at either the front or rear of the enclosure. A minimum gap of 25mm at the front and 50mm 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 the front, use in a fully enclosed rack installation is not recommended.
