4.13 Disk Installation

Required Tools

• Antistatic strap

• #2 Phillips screw driver

Procedure Steps

1. Attach the disk assembly bracket to the disk using the four retaining screws. Be sure the data (ribbon)

connector and power (4-wire) connector on the disk are facing the rear of the unit. Be sure the tab on the

disk assembly bracket is positioned towards the front of the unit.

2. Place the disk assembly over the retaining screws on the chassis shelf so that the tab on the bottom of the

assembly bracket is fully inserted into the opening in the chassis shelf.

3. Slide the disk assembly forward until it is stopped by the retaining screws in the slot.

4. Tighten the disk assembly retaining screws.

5. Reconnect the data (ribbon) cable and the data (4-wire) cable.

4.14 Entering Safe Mode

The unit can enter Safe Mode from any of three different means:

• Boot up fault detection – If a fault is detected during boot up that prevents the unit from running in Normal

Mode, it will enter Safe Mode.

• Normal Mode maintenance page – The administrator can command the server to restart such that the

server will enter Safe Mode after the restart.

• Front panel Safe Mode reset button – If the front panel Safe Mode reset button is pressed, the unit will

immediately restart into Safe Mode.

When in Safe Mode, the front panel Alert indicator will always be lit solid.

4.15 Connecting to Safe Mode Administration

The Safe Mode administrative interface to the server is accessed using a web browser. The steps to connect

to this interface are:

1. Plug your PC into one of the server’s LAN ports.

2. Set up the PC’s network interface to obtain an IP address automatically (using DHCP).

3. You may need to release and renew the PC’s IP address to get an address from the server.

4. Verify that the PC has an IP address on the 192.168.2 network.

5. Open your browser and enter the URL of http://192.168.2.254:8080.

4.16 Mirror Drive Replication

How to start replication

1. Enter Safe Mode as instructed in Entering Safe Mode and connect to the Safe Mode administration page

as instructed in Connecting to Safe Mode Administration.

2. Click on the Mount disk operation. The front panel Drive indicator will be lit solid. Copying the primary disk

to the secondary disk takes approximately 1 minute per gigabyte of data.

When replication is complete, reboot the server in Normal Mode.
