Dell PowerEdge 1800 - Manual (Page 11)

Table 1 -3 lists the drive indicator codes. Different codes are displayed as drive events occur in the system. For example, if a hard-drive fails, the "drive failed"
code appears. After the drive is selected for removal, the "drive being prepared for removal" code appears, followed by the "drive ready for insertion or
removal" code. After the replacement drive is installed, the "drive being prepared for operation" code appears, followed by the "drive online" code.

Connecting External Devices
When connecting external devices to your system, follow these guidelines:
l Most devices must be connected to a specific connector and device drivers must be installed before the device operates properly. (Device drivers are
normally included with your operating system software or with the device itself.) See the documentation that accompanied the device for specific
installation and configuration instructions.
l Always attach external devices while your system is turned off. Next, turn on any external devices before you turn on the system (unless the
documentation for the device specifies otherwise).
NOTE: If RAID is not activated, only the "drive online" indicator pattern appears. The drive-activity indicator also blinks when the drive is being accessed.
