Important: Make SURE that the enclosure is grounded before applying power.

Before you begin, make sure the site where you intend to set up and use your storage system has the following:

• Standard power from an independent source or a rack power distribution unit with a UPS.

• Host computer with the correct firmware,BIOSanddrivers.Contactyour supplier for the correct software levels.

1. Inspect the packaging for crushes, cuts, water damage or any other evidence of mishandling during transit. If any damage appears present, for future reference photograph the packaging before opening.

2. Unpack the system. See Figure 1.

Fit and check a suitable anti-static wrist or ankle strap and observe all conventional ESD precautions when handling plug-in modules and components. Avoid contact with backplane components and module connectors, etc. 1.2 Safety

2.2 Unpacking the Storage System

• An enclosure can weigh up to 57lb (26kg). Do not try to lift it by yourself.

• Do not lift the enclosure by the handles on the PCMs. They cannot take the weight.

Warning: Do not remove covers from the PCM. Danger of

Warning: Do not remove a PCM unless a replacement

Consider the following safety require-ments when mounted in a rack.

• The rack construction must be capable of supporting the total weight of the installed enclosures. To prevent the rack from tipping or being pushed over during installation or in normal use, incorporate stabilizing features.

• Whenloadingarackwiththeunits,fillthe rack from the bottom up and empty from the top down.

• To avoid danger of the rack toppling over, do not slide more than one enclosure out of the rack at a time.

• Operatethesystemwithlowpressurerear exhaust installation [back pressure created by rack doors and obstacles not to exceed 5 pascals (0.5mm water gauge)].

• The maximum operating ambient temperature for the unit is 96°F.

• Make sure the rack has a safe electrical distribution system. It must provide over-current protection for the unit. Do not overload the total number of units installed in the rack. Follow the electrical power consumption rating shown on the nameplate.

• The electrical distribution system must provide a reliable earth for each unit in the rack.

• Each power supply in each unit has an earth leakage current of 1.0mA. The design of the electrical distribution system must take into consideration the total earth leakage current from all the power supplies in all the units. The rack may require labelling with “HIGH LEAKAGE CURRENT. Earth connection essential before connecting supply”.

• Whenconfiguredwithenclosures,the rack must meet the safety requirements of UL 60950-1 and IEC 60950-1•

can be immediately added. The system must not be run without all units or module blanks in place.

Before setting up your enclosure ensure you have the following:

• SAS HBA • Mini-SAS to Host Cable• Power Cord • Rack kit (if installing within a rack)

Refer to your supplier for a list of qualifiedaccessoriesforusewiththeenclosure. The Accessory Box contains the power cords and other ordered accessories.

1. Remove the Rack Mounting Rail Kit from the Accessory Box and check for damage.

2. Attach left and right chassis slides to the enclosure sides using 8 M3 x 4 buttonhead screws (see Figure 2).

Assemble the left and right chassis latches using the special chassis latch screws. Ensure the latch is orientated as shown in Figure 2, with the spring arm located againstitsstop.Ontherighthandsidethisisatthetop,ontheleftatthebottom.Assemble the rack brackets to the rack posts as follows (see Figure 3):

1. Position the location pin at the rear of the rail into a rear rack post hole. Attach the bracket to the rear rack post using the washers and screws supplied. The screws should be left loose.

2. Extendrailtofitbetweenthefrontandrearrackposts.

3. Attach the bracket to the front rack post using the washers and screws supplied. The screws should be left loose.

4. Tighten the two clamping screws located along the inside of the rear section of the rack bracket (see Figure 3).

Mount the enclosure into the rack as follows (see Figure 4):

1. Lift the enclosure and align it with the rack rails.

2. Carefully insert the chassis slides into the rack rails and push fully home.

3. Tighten the rear rack bracket mounting screws.

4. Withdraw enclosure until it reaches the hard stops (approximately. 400mm) and tighten the front rack bracket mounting screws.

5. Return the enclosure to the fully home position.

3 Installation

• Operatetheenclosurefromapowersupply input voltage range of 100-240 VAC.

• The plug on the power supply cord is used as the main disconnect device. Make that outlets are located near the equipment and are easily accessible.

• When powered by multiple AC sources, disconnect all supply power for complete isolation.

• To comply with applicable safety, emission and thermal requirements do not remove covers. Populate all bays with plug-in modules.

• Always disconnect the power prior to removal of a PCM from the enclosure.

• Provide a safe electrical earth connection to the power supply 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 technicalspecification.

• When bifurcated power cords (‘Y’ leads) are used, connect them only to a supply range of 200-240 V.

• Replace a faulty PCM with a fully operational module within 24 hrs.

• Do not remove a faulty PCM unless you have a replacement model of the correct type ready for insertion.

Important: The following rack installation procedure is an example for illustration purposes only. You may have different rack brackets and different slides. Check with the rail kit manual that came with your rack for complete instructions.
