StorageLoader Installation and User Manual 13 Tandberg Data Operation and Configuration 3. Installation This chapt er provides st ep- by- st ep inst ruct ions on how t o properly prepare and install the Tandberg Data StorageLoader. READ ME FIRST CAUTION! ! YOU MUST REMOVE THE ROBOT TRANSPORT LOCK WHEN POWERING UP THE UNIT FOR THE FIRST TIME OR IT WILL NOT OPERATE. SEE THE PROCEDURE ON THE FOLLOWING PAGES. 3.1 Performing the Installation To install the StorageLoader, complete the following steps. Step 1. Unpacking the StorageLoader Carefully unpack t he unit from t he shipping cont ainer. Save t he cont ainer and packing m at erials in case you need t o t ransport t he St orageLoader in t he fut ure. The packaging is specifically designed for the loader to ensure it is not damaged during transportation. Review t he cont ent s of t he shipping cont ainer t o be sure t hat all part s were included in t he shipm ent . A st andard package for t he StorageLoader consists of the following items: A fact ory- assem bled cartridge magazines. St orageLoader unit cont aining t wo A Standard Accessory Kit containing: - 1 The Tandberg Dat a St orageLoader CD cont aining all manuals - 1 Printed copy of the Quick Installation Guide - 1 Warranty/Registration Card - Rack Mount Hardware Kit 14 StorageLoader Installation and User Manual Tandberg Data Operation and Configuration - 2 Line Power Cords: one for USA/ Japan and one for European power outlets - 1 VHDCI SCSI Interface Cable - 1 68- pin VHDCI LVD/SE SCSI Terminator. - 1 Ethernet cable - Tool for Emergency Magazine Release - 30 StorageLoader specific Bar code labels There will be variat ions of t his list . Please also refer t o your Quick I nstallation guide shipped with the StorageLoader. Note: The StorageLoader contains no cartridges before shipment. Step 2. Installing the StorageLoader in a Rack The StorageLoader is designed for use in 19" rack system using 1U of rack space. The lengt h of t he power cord and t he SCSI cable may restrict the placement. Attention: The St orageLoader is designed t o operat e in a horizont al posit ion. Do not at t em pt t o operat e t he St orageLoader in any other position than horizontally. Also make sure that: The airflow around t he front and back of t he St orageLoader is not obstructed. There is a minimum of 60cm free space in front of the unit to allow the operator to safely remove the magazines. The display and operator controls are easily accessed. The St orageLoader is away from t he floor , and in a clean environm ent wit h t em perat ure wit hin specificat ion, see Appendix A. The Rack Mounting Kit includes the following items: Rail Left Assembly Rail Right Assembly Screw M6x12 (6 pieces) Screw M5x8 (2 pieces) Recommended mounting tools: StorageLoader Installation and User Manual 15 Tandberg Data Operation and Configuration Folding rule or tape measure Screwdriver 7 mm open- end wrench Note: The rails are m ount ed t o t he loader during t ransport at ion. Before mounting the rails into the rack, dismount the rails from the loader and remove the spacers between the rails and the loader. Back Rail Right Assembly Rail Left Assembly Front Figure 3.1 Rack Mounting kit Installing the Rack Mounting Kit Determine the proper position of the rails in the rack. Caution: Consider rack st abilit y when deciding where t o place t he St orageLoader, hazardous condit ions can be t he result of uneven mechanical loading of a rack. 16 StorageLoader Installation and User Manual Tandberg Data Operation and Configuration St orageLoader 1U uses 1U of vert ical rack space. The rails m ust be inst alled in a full U posit ion ( The bot t om of t he rails m ust be aligned wit h t he bottom of a U), see figure 3.2. Figure 3.2 Rack mount rail Installing the "Rail Left Assembly" 1. Measure t he lengt h bet ween t he rear rack m ount rails and t he front rack m ount rails. I f t he m easurem ent is short er t han t he St orageLoader, m ove t he t wo set s of screws M4x12, washers and nuts shown in Figure 3.3. 2. Adj ust t he " Rail Left Assem bly" t o fit t he m easurem ent in step 1. 3. Use a 7 mm open- end wrench together with the screwdriver to tighten the two M4x12 screws to fix the rail length. Note: Using more than two screws will increase the stability of the Rack Mounting Kit. 4. Place t he " Rail Left Assem bly" on t he left side of t he rack, bet ween t he rear rack m ount rail and t he front rack m ount rail. 5. Mount t he " Rail Left Assem bly" at desired height using one M6x12 screw in front (upper hole in rail only) and two M6x12 screws at the backside. See figure 3.4. Installing the "Rail Right Assembly" Follow t he inst ruct ion for left side only using t he " Rail Right Assembly" on the right side of the rack. StorageLoader Installation and User Manual 17 Tandberg Data Operation and Configuration Rear Rack Mount Rail Use these holes if rack depth is equal or longer than the StorageLoader Step 1 Holes to be used if rack depth is shorter than the StorageLoader Step 5 (Screw M6x12) Step 1 Front Rack Mount Rail Step 3 (Screw M4x12, nut and washer) Step 2 Step 5 (Screw M6x12) Figure 3.3 Mounting the Rack mounting kit to a rack Figure 3.4 shows st ep 5 in t he description: Rack m ount ing kit m ount ed in rack wit h one screw M6x12 in upper hole on both left and right side. On t he rear side t wo screws m ust be used on bot h left and right side. Tot ally six screws are used t o inst all t he " rack m ounting kit" to the rack. Figure 3.4 Rack mounting kit mounted in rack Mounting the StorageLoader to the Rack Make sure t hat all t he screws in t he Rack Mount ing Kit are tightened properly before installing the StorageLoader in the rack. 18 StorageLoader Installation and User Manual
