The system must not be run without all modules in place. Permanently unplug the unit if you think that it has become damaged in any way and before you move it ✦ ✦ A LaCie 12big Rack Serial can weigh up to 32kg (70.4lb). Do not try to lift it by yourself. ✦ ✦ Do not lift A LaCie 12big Rack Se- rial by the handles on the plug-in modules or those on the front of the enclosure, they are not designed to support the weight of the enclosure. ✦ ✦ In order to comply with applicable safety, emission and thermal re- quirements no covers should be re- moved and all bays must be fitted with plug-in modules. Power Supply Safety LaCie 12big Rack Serials must only be oper- ated from an AC power supply input voltage range of: 100 to 120VAC or 200 to 240VAC. AC PSU Safety Precautions ✦ ✦ The power cord/cable on the power supply is used as the main discon- nect device. Ensure that the socket outlets are located near the equip- ment and are easily accessible. ✦ ✦ The equipment is designed to be op- erated with two working Power Supply modules. ✦ ✦ To prevent overheating do not op- erate the enclosure with one power supply removed for more than 30 minutes. ✦ ✦ Disconnect all supply power for complete isolation. ✦ ✦ The power connection must always be disconnected prior to removal of the Power Supply module from the enclosure. ✦ ✦ A safe electrical earth connection must be provided to the power cords. Check the grounding of the enclosure before applying power. ✦ ✦ Provide a suitable power source with electrical overload protection to meet the requirements laid down in the technical specification. CAUTION: Do not remove covers from the Power Supply module. Danger of elec- tric shock inside. Return the Power Supply module to your supplier for repair. CAUTION: If this equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. Rack System Precautions The following safety requirements must be considered when the enclosure is mount- ed in a rack. ✦ ✦ The rack design should incorporate stabilizing features suitable to pre- vent the rack from tipping or being pushed over during installation or in normal use. ✦ ✦ Do not slide more than one enclo- sure out of the rack at one time to avoid the danger of the rack top- pling over. ✦ ✦ Always remove all modules and drives to minimize weight before loading chassis into a rack. ✦ ✦ When loading a rack with the units, fill the rack from the bottom up and empty from the top down. ✦ ✦ System must be operated with low pressure rear exhaust installation (back pressure created by rack doors and obstacles not to exceed 5 pascals (0.5 mm water gauge)). ✦ ✦ The rack design should take into consideration the maximum oper- ating ambient temperature for the unit, which is 40°C (104°F) when two power supply modules are fit- ted. ✦ ✦ The rack should have a safe elec- trical distribution system. It must provide overcurrent protection for the enclosure and must not be overloaded by the total number of enclosures installed in the rack. Consideration of the chassis name- plate rating should be used when addressing these concerns. ✦ ✦ The electrical distribution system must provide a reliable earth for each unit and the rack. ✦ ✦ Each power supply in each enclo- sure has an ground (earth) leakage current of <1.5 mA maximum at 60 Hz, 264V per power supply. The de- sign of the electrical distribution sys- tem must take into consideration the total ground (earth) leakage current from all the power supplies in all the enclosures. The rack will require la- belling with “HIGH LEAKAGE CUR- RENT. Ground (earth) connection essential before connecting supply.” ✦ ✦ The rack when configured with the enclosures must meet the safety re- quirements of UL 60950-1 and IEC 60950-1/EN 60950-1.

Single Fan failure. Both fans fail: Replace faulty Cooling mod- ule. Single fan fails: the complete Cooling mod- ule must be replaced. 4.3.4. Thermal Control The LaCie 12big Rack Serial uses extensive thermal monitoring and take 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 13 - Troubleshooting Thermal Control Symptom Cause Action 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 tem- perature rise. NOTE: This is not a fault condi- tion. 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 am- bient temperatures in the local environment and may be perfectly normal. NOTE: This threshold changes according to the number of drives and power supplies fitted. 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. Reduce the ambient temperature.

Dealing with Hardware Faults Ensure that you have obtained a replacement module of the same type before removing any faulty module. CAUTION: If your LaCie 12big Rack Serial is powered up and you remove any module, replace it immediately. If the enclosure is used with plug-in modules, Dummy Carriers or Blank modules missing for more than a few minutes, the Enclosure can overheat, causing power failure and data loss. Such use will invalidate the warranty. ✦ ✦ Replace a faulty drive with a drive of the same type and equal or greater capacity. ✦ ✦ All drive bays must be fitted with a SAS/SATA Drive Carrier or Dummy Carrier module in order to maintain a balanced air flow. ✦ ✦ All of the supplied plug-in power supply units, electronics modules, dummy carriers and blank modules must be in place for the air to flow correctly around the cabinet. Please refer to 5. Module Removal & Replacement for details of module removal/replacement procedures. 4.5. Continuous Operation During Replacement Depending on how the LaCie 12big Rack Serial is configured, if a disk unit fails, it can normally be replaced without interrupting the use of the system. In addition, each enclosure contains two PSUs, either of which can maintain power and cooling to the subsystem while the other is re- placed. NOTE: The PSU replacement time must be as short as possible (<30 minutes) as the enclosure is designed to operate with two PSUs installed. IMPORTANT INFO: in the event of a cooling fan failure the com- plete Dual Fan Cooling Module must be replaced within <10 sec- onds. 4.6. I/O Module Firmware Upgrade LaCie periodically issues updates to the Storage Enclosure Processor (SEP) firmware as part of a scheduled release package, this code needs to be loaded onto each I/O in the enclosure. There are two ways to perform this upgrade, one uses the diagnostic serial port on the LaCie 12big Rack Serial (Out of Band) and the other uses SCSI commands over the SAS topology (In Band) 4.6.1. I/O Module Firmware Upgrade Out of Band This method uses a Host PC running a ‘terminal’ application to download the firmware using an RS232 serial cable to connect to the I/O module to be upgraded. Instructions for this method are supplied with the upgrade package in the LaCie 12big Rack Serial Upgrade Procedure document. 4.6.2. I/O Module Firmware Upgrade In Band This method uses the data path to transfer the firmware update to the LaCie 12big Rack Serial, hence no extra cables should be re- quired. SCSI commands are issued to transfer the data blocks. There are two methodologies, the preferred method uses SES page 0x0E download but a Write Buffer method is also available. 4.7. Drive Firmware Upgrade CAUTION: Upgrading firmware in SAS and SATA drives should only be performed by the most experienced users. If firmware is in- correctly upgraded it could result in a drive becoming non-func- tional.
