Advanced Information Capacity Expansion The RAID capacity can be expanded by add one or more Disk Drive into the existing RAID group and properly setup procedures. 1. Add new HDD into the RAID system. 2. Configuration through the RS-232 Terminal mode, move the cursor to " On-Line Expand " and " Enable " and press " Enter " to confirm it. ( If you have not add any new HDD into the RAID group the " Enable " item will not show up.
Chapter 5 : " Hot Swap " This chapter explains how to remove and install the "Hot-Swap" parts without interrupting the data access while the disk array is on. The "Hot-Swap" parts include : Hard Disk Drives Redundant Power Supply Units Cooling Fans Follow the steps below and refer to the diagrams to remove and install the "Hot-Swap" parts.
Hot Swap Removing / Installing Hard Disk drives a.
Hot Swap b.
Hot Swap c.
Hot Swap d. Replace with a new Hard Disk Drive It must be same capacity or greater than the faulty drive, if you replace with a Hard disk Drive of insufficient capacity, the Disk Array's built-in buzzer will sound and the intelligent Auto-Rebuild function will not be started. * For best performance, we recommend you swap with an identical Hard Disk Drive. e.
Hot Swap Removing / Installing the Redundant P/S Unit There are two LED indicators on the front panel which display the status of the redundant power supplies. While the power supply is power-on the #1st LED indicators lights up " Green ", if any one them fail, the #2nd LED indicator will lights up " Red " and the power supply's buzzer alarm will sound.

Appendix How to Setup Active Terminator For better data integrity, we suggest you always add an active terminator on the Disk Array. Please follow the Steps below : 1. Plug-in the Terminator before Power-On : You can find two ports for the host channel adapter on the back of Disk Array. You can connect the top one with your Host Computer, and plug in the active terminator on the second one. 2.
