To install the DRAM SIMM, open the top panel by removing the four screws. 72-Pin DRAM in SIMM Socket Clip Mounting Hole Plastic Safety Tab (This Side Only) Mounting Hole Installing DRAM SIMM The DA3000 RAID controller is equipped with two SIMM sockets.
II. System Components Fixed Storage Device Tray The DA3000 is mounted on a removable tray, secured by four screws (as circled). DA3000 Installation II. Components A metal clip on each side of the device tray (as pointed to) secures the tray in place. To release the tray, press these clips in with your fingers . Fixed Device Spacer Insert the device tray along with the DA3000 into the device bay. Cover it with a spacer to complete the installation.
II. System Components • 2-6. Front Panel of the DA3000 RAID Controller The front panel of the DA3000 RAID controller consists of an LCD display, keypad and status LEDs, which allow you full access to status information and complete control of the RAID operation. II.
II. System Components • 2-7. Hot-Swap SCA Hard Drive Modules Maximum uptime in a system requires devices that can be easily replaced or “swapped.” The main hard drives are mounted in internal hot-swap trays for easy replacement. The AR1000 hot-swap bay has two different models: Five-tray hot-swap bay and three-tray hot-swap bay. The 1.0 inch SCA hot-swap bay can accommodate five 1.0 inch hard disk drives. The 1.6 inch SCA hot-swap bay can accommodate three 1.6 or 1.0 inch hard disk drives. Hot-Swap Bay II.
II. System Components 1 2 4 5 Hot-Swap Bay II. Components 3 Hot-Swap Tray Hot-Swap Bay There are two levers on the front of the hot-swap tray to help release or lock the tray. To remove the tray, extend both levers and pull on both levers. To install the tray, push the tray firmly into the bay with the levers extended, then close the levers. Hot-Swap Bay To remove the hot-swap bay, first release the front cooling fans first by pressing the eject mechanism with a small screwdriver.
II. System Components • 2-8. Front Cooling Fans The front cooling fan module consists of a control board, a hard disk drive LED status board, and two cooling fans. The message LED board mounted in the front of the cooling fan module consists of five sets of LEDs to represent the status of up to five hard disk drives. Each set has three LEDs which can show the power, activity, and status of each hard disk drive. Front Cooling Fans II.
