The J4400 weighs up to 91 pounds (42 kg) fully loaded. You should remove the disks before sliding the tray into the cabinet so that it is easier to lift. Removing a Disk Drive describes this procedure.
|
|
Caution - The power supplies in this equipment can produce high energy hazards. Only trained personnel with authorized access to this equipment should remove and replace modules in the system. |
|
|
Caution - The replacement disk drive must be the same capacity and same type as the disk drive it is replacing. |
|
|
Caution - Never remove a disk drive unless the ID/Status LED is blue (see FIGURE 1-1). If you need to remove multiple disk drives, always remove and replace one disk drive at a time. |
| Note - The disks are hot-swappable and you do not need to disconnect power from the system or other components in order to replace one of these parts. |
This section describes how to remove a disk drive.
1. From the front of the disk tray, locate the disk drives (see FIGURE 2-11) you want to remove. The Activity LED is off and the ID/Status LED is blue, indicating that data is not being transferred to or from the disk and that the disk drive is ready to remove.
|
|
Caution - Potential loss of data access - Data might be lost if an active disk drive is removed. If you remove an active disk drive accidentally, wait at least 30 seconds before reinserting it. |
2. Press the release button in and to the right to release the disk ejection lever.
3. Pull the disk ejection lever fully open to unlock and partially eject the disk drive from the tray.
