Accusys 76500/76510 Familiarizing yourself with the controller Overview The RAID box has three drive carriers, accessed from the front. The sides of the box each feature a guide rail channel and mounting screw holes to enable the box to be secured inside a computer case. The connectors and jumpers are located on the rear panel.
Chapter 1 – Introduction Disk Activity Indicators These indicators show the status of each individual disk drive. Indicator Green Amber Red Red busy Flashing Red slow Flashing Disk Activity Disk drive is properly installed and locked Disk drive is being accessed Disk drive is not present, is not properly installed, is unlocked, or disk has failed Disk drive is rebuilding data. The backup disk marking at the rate of 0.5sec/on2Sec./off (move in circle).
Accusys 76500/76510 The settings for the master / slave are described in Chapter 3. (only for ACS-76500) The IDE/SATA cable is the route used for reading and writing to the array. The power connector supplies power to the RAID box. In order to provide stable power, we recommend to connect both power connectors on the RAID box. The 3-pin RS-232 cable is used for remote monitoring of ACS-76500/76510. The RS-232 port is configured with DTE and PC compatible pin assignments.
Chapter 2 – Before you begin Chapter 2 Before you begin This chapter contains includes all the information about RAID level and preparing for installation. You will find: A full introduction and comparison of RAID level 1 Important notices on the safe operation and installation of ACS-76500/76510 Pre-installation planning Introduction to RAID level The ACS-76500/76510 can support the following RAID level 1+backup. RAID Level 1 supports three disk channels with the “backup” function.
Accusys 76500/76510 RAID 1 RAID 1 is commonly referred to as Disk Mirroring, Disk Shadowing or Disk Duplexing as all data is duplicated across both disks. RAID 1 can only be performed with two hard drives (with four drives, RAID 0+1 is configured automatically). As data is identical on both disks, storage capacity is that of the smaller disk. RAID 1 has poor performance for write operations but very high performance for read intensive operations.
Chapter 2 – Before you begin Backup function When executing the backup feature, the controller turns the target HDD to be backup and the backup HDD to be target. The controller continues to mirror data from the source HDD to the target HDD. The backup function is available only when the RAID is safe. If the RAID health is in good state, you may execute the backup function. The RAID health refers to the state of both the source and target HDD. Failure of either of the HDDs causes unsafe RAID.
Accusys 76500/76510 Static electricity can damage electronic components. To guard against such damage: Work in a static-free environment Wear a grounded anti-static wrist strap Store uninstalled components in anti-static bags Handle PCBs by their edges and avoid touching chips and connectors.
Chapter 3 – Setting up the RAID box Chapter 3 Setting up the controller This chapter explains how to: Set master or slave configuration on RAID box (only for ACS-76500) Install the RAID box in a system or externally Load hard drives into ACS-76500/76510 Installation flowchart Installation of ACS-76500/76510 is simple. This chapter will lead you though the following steps: Configure RAID box Install RAID box Load hard Use jumpers to set master or slave tatus (only for ACS-76500).
Accusys 76500/76510 Setting configurations The master / slave configurations are set manually by placing jumper heads on the nine jumper pins on the rear of the RAID box (Only for ACS-76500). Master and slave settings enable your computer to distinguish two IDE/ATA devices operating on the same channel. In this case, the settings distinguish ACS-76500 from your computer’s hard disk drive.
Chapter 3 – Setting up the RAID box Mounting RAID box The ACS-76500/76510 RAID box can be installed inside a computer case or set up externally. This section describes both procedures. Turn off and disconnect all electrical power from the system before beginning installation. Mounting RAID box in system The ACS-76500/76510 RAID box fits into the space of two half-height 5¼-inch drive bays. 1. Remove the cover and front bezel from the system case. 2. Feed a power cable through the opening. 3.
Accusys 76500/76510 6. Insert the RAID box into the bay, and secure it in place with the screws provided. (If your case uses guide rails to install 5¼-inch devices, you can use them on the RAID box.) In order to provide stable power, we recommend to connect both power connectors on the RAID box.
Chapter 3 – Setting up the RAID box Loading drives in the RAID box All three hard disks should be configured as Master (only for ACS -76500). There are two types of drive carrier available for ACS-76500 controller: Fixed IDE connector Drive Carrier Fixed IDE Connector Power Connector There is one type of drive carrier available for ACS-76510 controller.
Accusys 76500/76510 Fixed connector drive carrier The ACS-76500/76510 should be fitted with three hard disk drives. Load each drive into a drive carrier as follows: For ACS-76500 1. Unlock the drive carrier and slide it out of the RAID box. 2. Place the disk drive in the drive carrier, so that the power and IDE connectors are lined up with the connectors inside the carrier. 3.
Chapter 3 – Setting up the RAID box Removing / replacing a drive Swapping drives The hot swap function is available on the RAID 1 array and can be operated during run time. RAID rebuilding will be processed automatically in the background and the ACS-76500/76510 RAID subsystem will record its progress. If the host system is shut down or powered off abnormally, the ACS-76500/76510 RAID subsystem will continue the disk rebuilding process after power is turned on again.
Accusys 76500/76510 Firmware updating steps 1. Ensure the ACS-76500/76510 is turned off. 2. Connect the RS-232 cable to the RS-232 3pin port (Please refer the page 11 “Rear View”), and connect the other end to one of the host computer’s COM port. 3. Launch HyperTerminal from the host computer: Start > Programs > Accessories > Communications > HyperTerminal. 4. Select COM1 or COM2 from the Connect using: dropdown menu, depending on which port is connecter to ACS-76500/76510. 5.

Accusys 76500/76510 Chapter 4 Application The configuration of your controller decides the way you use the RAID. This chapter guides you through ways of using RAID according to the number of disk drives you installed. If you have installed three new disk drives go to Application 1. If you have installed two new disk drives go to Application 2. If you have installed one drive with data and one new disk drive go to Application 3. Application 1: Three new disk drives. 1.
Chapter 4 – Initializing the array Application 3: Installing one disk with data and one new disk 1. The new drive must have the same capacity or larger capacity than the drive with data. 2. Lock the disk with data at the first disk tray and leave the new disk unlocked at the second disk tray. This identifies the disk with data as the source drive. (The computer must in power off state.) 3. Power on the computer system. 4. Lock the new disk. 5.
Accusys 76500/76510 Appendix A FAQ If you encounter a problem while using the ACS-76500/76510, check this section for help. 1. When I lock a drive carrier with a disk drive in place, the red disk activity indicator turns on and an alarm beep sounds. Why? (a) Make sure you firmly connect the IDE/SATA and Power connectors of the HDD to their counterparts inside the drive carrier and try again. If this does not solve the situation, go to (b). (b) Change the disk drive with a new one and try again.
