Preface Important Safety Instructions, Care and Handling Before starting with the RAID installation, read this user manual carefully and save it for later reference. Do not place the RAID system near a radiator or other heat source. If an extension cord or power center is used with the RAID system, make sure that the total current consumption plugged into the wall outlet does not exceed the ampere rating.
With its advanced storage management capabilities, the RAID system is an excellent choice for both on-line and near-line storage applications. The following sections in this chapter will present an overview of the features of SS-4503E/SS-4503R RAID system. 1.1 Package Contents The following items come with your RAID system package, if any of them is missing or damaged, please contact your supplier.
• Flat and stable surface capable of supporting the RAID system LAN management port settings SS-4503E/SS-4503R support DHCP (Dynamic Host Configuration Protocol) to establish an IP address. To know current IP address by simultaneously pressing ENT + EXT button on the front panel twice.

This section describes the process in installing different types of hard disk drives, and mounting the RAID system. 2.1 Installing the Hard Disks Both SS-4503E and SS-4503R RAID systems support SAS or SATA interface hard drives. Caution It is recommended to mount the RAID system to the rack cabinet first before installing the hard drives and the drive trays.

Hardware Installation 4. Insert the hard disk trays into the empty slots. 5. Push down the tray handle to secure the hard disk tray into place. 6. Repeat steps 4 to 5 until all the required disks have been installed. 7.
Hardware Installation 2.1.2 SATA hard disks SATA hard drive installation requires a AA-MUX tray board to be installed on the hard disk tray first before installing the SATA hard disk. AA-MUX Tray Board Because of the relatively high prices of SAS hard drives, SATA hard drives are more widely used at the moment. AA- MUX tray board is equipped with SATA connector on one end and SAS connector on the other end to enable RAID system connetions.

Hardware Installation 3. Slide the hard disk towards the AA-MUX tray board and connect the power and data connectors. 4. Attach the screws to secure the hard disk. 5. Insert the hard disk tray into an empty slot. 6. Push down the tray handle to secure the hard disk tray into place. 7.
Hardware Installation 8. Close the front panel door, then lock it. Tray LED Indication Color Status Bule Access Green Disk Online No Disk 2.1.3 Combining SATA SAS Disk Consider to different hardware architecture of SAS and SATA disk, the properly configuration of placing disks is most important for high data availability of RAID system.
Hardware Installation 2.2 Mounting the RAID system The RAID system can be installed in a standard 19-inch rack. Follow the procedures below: 1. Attack eight rack nuts into the rack, making sure that they correspond with the mounting points on the rails. 2.
Hardware Installation 2.2.1 Installing the Rail Extenders If the front door was stocked by obstacle chassis at botton side, please follow the procedures below to install the rail extenders. Follow the procedures below to install the rail extenders: 1. Install the rail extenders and attach the screws to secure them. 2.
Connect the other end of the cable to the iSCSI HBA connector of the host server or Gigabit ethernet switch. 3.2 Connecting the GUI Management Port To easily monitor and configure the RAID system, SS-4503E / SS-4503R can be managed using Graphical User Interface (GUI). To manage the GUI, a LAN/WAN connection is required. Follow the procedures below: 1.
System Connections 3.3 Connecting the CLI Management Port The RAID system can be managed using the CLI. To connect the CLI management port, follow the procedures below: 1. Insert the terminal cable into the COM port. 2. Insert the other end to an external terminal. Note •...
System Connections 3.5 Connecting and Turning On the Power Once all of the components have been installed into the RAID system, and the management interfaces have been connected, the RAID system can now be powered on. 1. Plug one power cable into the AC power port.(A) 2.
Maintenance Chapter 4: Maintenance This chapter describes the procedures in maintening the RAID system components to ensure performance quality and stability. 4.1 Replacing a Disk When a hard disk fails, the Disk LED indicator lights red and the audible alert sounds. Note To turn off the audible alert, simultaneously press the Up and Down buttons on the front panel twice.
Maintenance 4.2 Replacing a Controller The RAID controller monitors and manages the logical drives. When the controller is replaced, all the logical drive data remains intact because the logical drive information is stored on the disk drives. When a controller fails, you can replace the controller with a new one. The controllers are hot-swappable, which means they can be replaced even when the RAID system is powered on and functioning.
Maintenance 4.3 Replacing a Power Supply A failed power supply is indicated when: • the Power Supply (P/S Fail) LED indicator turns red • the audible alert sounds • the LCD displays “Power failure”. Note To turn off the audible alert, simultaneously press the Up and Down buttons on the front panel twice.
Maintenance 6. Tighten the screws back to secure the power supply. 4.4 Upgrading Memory For faster and more efficient performance, you can upgrade the memory of the RAID controller. Follow the procedures below: 1. Loosen the screws of the controller. 2.
Maintenance 4. Gently push the new memory card into the socket. 5. Push the corners of the memory until the retaining clips click into place. 6. Insert the controller back into the slot, then push down the handle to loc. 7.
Maintenance 4.6 Installing Battery Backup Module In case of a power failure, the Battery Backup Module (BBM) can sustain cache memory. BBM is highly recommended in order to avoid data loss or inconsistency. However, BBM is an optional accessory which can be purchased separately from your supplier.
Specifications Appendix B: Accessories The following lists other components and accessories that can be used with the RAID system and are purchased separetely: • SAS JBOD SS-6692E / SS-6692R / SS-8892E / SS-8892R • AA-MUX tray board (for SATA Hard Disk) •...
