Chapter 3 Installing the DSN-1100 Storage System This chapter describes how to install the DSN-1100 storage system. The topics covered in this chapter are: Section 3.1, Site Considerations Section 3.2, Unpacking the DSN-1100 Storage System Section 3.3, Items Supplied by the User Section 3.4, Connecting to the iSCSI Data Ports Section 3.5, Connecting to the Management Port Section 3.6, Connecting the Power Cords Section 3.
3.1 Site Considerations The site where you install the DSN-1100 storage system can affect its performance. Therefore, choose a site that conforms to the requirements in the following sections. 3.1.1 General Considerations Observe the following considerations when selecting a location to install the DSN-1100 storage system. 3.1.2 The location should be fairly cool and dry for the acceptable temperature and humidity ranges.
3.2 Unpacking the DSN-1100 Storage System After receiving the DSN-1100 storage system, perform the following steps to ensure that it and other contents arrived safely. 1. Inspect the outer shipping container for any damage that may have occurred in shipping. Report any sign of damage to the appropriate shipping agency. 2. Remove the DSN-1100 storage system and cables from the shipping container. 3.
3.4 Connecting to the iSCSI Data Ports The following sections describe how to connect the DSN-1100 data ports. 3.4.1 Connecting to the DSN-1100 Host Network Connection Ports The DSN-1100 storage system has four RJ-45 data ports. These ports connect to your SAN using either a straight-through or cross-over RJ-45 Ethernet cable (the DSN-1100 storage system auto-senses the type of cable used). One cable is needed for each RJ-45 data port. 1.
3.6 Connecting the Power Cords The DSN-1100 storage system has a single power receptacle: 1. Plug the female end of the power cord into the 3-pronged power connectors on the back of the DSN-1100 storage system. Plug the other end of the power cord into a working AC outlet that is not controlled by a wall switch. 3.7 Powering-on the DSN-1100 Storage System To power-on the DSN-1100 storage system, press the power switch located inside the front cover.

Appendix A Replacing and Upgrading FRUs This appendix describes how to replace or upgrade the Field Replaceable Units (FRUs) in your DSN-1100 storage system. FRUs that can be replaced or upgraded include: A.1 Battery Pack System and buffer memory SATA drives Fans Power supply Removing the Cover To remove the cover, use the following procedure. 1. Power down the DSN-1100 storage system and remove the power cord from the back panel. 2. Attach an ESD-preventive wrist strap. 3.

A.2 Installing the Battery Pack The xStack Storage Array accommodates a shrink-wrapped battery pack. Because write-back caching is always enabled, we recommend you have a battery to back up the buffer cache contents. The battery pack connects to the DSN-1100 controller board using a 3-pin locking connector at J11 (see Figure A-3 for detailed drawing of its location).
To install a battery in your xStack Storage SAN Array, follow these steps: 1. Hold the battery as shown to align the fastener strips. Make sure the battery cable and connector is located nearest to the battery socket J11 on the controller (see Figure A-4). Figure A-4 Aligning the Battery 2. Press the battery down firmly as shown in Figure A-5 until you feel it lock into place.
3. Carefully feed the battery’s connector up through the hole in the mounting plate as shown in Figure A-6. Do not damage the insulation on the wires. Figure A-6 Align the Battery Plug with Connector J11 4. Align the battery plug with connector J11 as shown in Figure A-7 and insert it fully into the socket.
5. The connector locked firmly into connector J11 as shown in Figure A-8. Figure A-8 Battery Plug Locked in Place 6. The installed battery is shown in Figure A-9.
A.3 Upgrading or Replacing Memory Your DSN-1100 storage system supports up to 1 GB of buffer(cache) memory and 512 MB of system memory using a total of two Dual In-line Memory Module (DIMM) sockets on the DSN1100 storage system Controller: One DIMM sockets (J14) is for buffer (cache) memory. One DIMM socket (J15) is for system memory. System Memory: The xStack Storage controller can address up to 512MB of system memory. Your controller comes standard with 256MB (1 x 256MB module).
Figure A-11 Buffer(Cache) Memory DIMM Socket Figure A-12 System Memory DIMM Socket 32 Appendix A Replacing and Upgrading FRUs
Table A-1. xStack Storage Array DIMM Specifications Requirement Description PC2700/DDR333 speed SDRAMs must be JEDEC compliant and DDR333 capable, with a CAS latency of 2.5. PC2100/DDR400 speed DIMMs can be used if they support a 2.5 CAS latency when operating at DDR333 speed. ECC DIMMs must be organized as x72 bits wide, allowing support for ECC. X8 RAMs DIMMs must use 8-bit wide DRAMs that can support data mask (DM) signals.
Figure A-13. Removing a DIMM Module 7. Hold the new DIMM above the DIMM socket, so its polarization notch is located at the right end of the DIMM socket. 8. Slowly insert the new DIMM by sliding the end with the metal fingers into the DIMM socket (see Figure A-14). Stop sliding when the DIMMM is securely seated in the socket. Figure A-14. Inserting a DIMM 9. Snap the latches into place. Do not use excessive force, because the socket might break. 10. Replace the cover (see section A.1). 11.
A.3 Installing or Replacing SATA Drive Removal of a populated drive/tray assembly can have unforeseen effects including the loss of all data in a volume. A drive can be part of a volume that may or may not be redundant. Before removing a drive from an operating xStack Storage Array, make sure it is the correct one. A.3.
A.3.2 Installing a Hard Drive in a Drive Tray Follow these steps to install a hard drive in a drive tray. 1. If there is one, remove the plastic air dam from the tray by squeezing the two levers together and lifting the piece out of the tray as shown in A-17. Figure A-17 Removing the Plastic Air Dam Piece 2. Your tray should now look like Figure A-18.
3. Place new hard drive in tray as shown in Figure A-19. Figure A-19 Place Hard Drive in Tray 4. Align the mounting holes and insert four mounting screws to hold the drive securely in the drive tray as shown in Figure A-.
5. Your hard drive is ready for installation. Proceed to A.3.3. A.3.3 Drive and Tray Installation A drive/tray assembly can be installed by inserting the drive/tray assembly into the open drive bay as shown in Figure A-21. Push the tray at the point indicated in Step 2 of Figure A-22 and push until it is seated firmly within the bay. As you press, you will see the tray handle begin to move inwards as the locking mechanism enters the locking slot.
