Table 1-1 Front Panel Controls and Indicators

Control or Indicator Purpose

LCD

2-line by 20-character LCD. Displays drive status, error messages, and POST results.

Status LED

Provides information about the state of the drive. The Status LED is either green or

amber, and can be solid or flashing (refer to Table 3-2 in Chapter 3 Operation and

Maintenance for a description of the Status LED states).

character code for:

Diagnostic or maintenance functions

Error conditions and informational messages

Single Red Dot

(LTO 400D only) The Single Red dot is located on the single-character display. When

it is on, the drive has created a dump. For information on copying the dump to a tape,

see Maintenance Mode.

Unload Button

The Unload button enables you to perform several functions.

Press the Unload button once to start a manual unload of the tape.

Note

During a rewind and eject operation, your LTO standalone will not accept

SCSI commands from your host.

Press the Unload button three times within one second to place your LTO standalone

in Maintenance Mode (refer to Chapter 4 Troubleshooting and Diagnostics for a

description of Maintenance Mode functions and a description of the functions the

Unload button can perform while in this mode).

Note

While in Maintenance Mode, your LTO standalone will not accept SCSI

commands from your host.

Press and hold the Unload button for 10 seconds while your LTO standalone is in

normal operating mode, to force a drive dump (save a microcode trace). The drive

places the dump data into a special dump area where it is retrievable (refer to Chapter

4 Troubleshooting and Diagnostics for a description of the Force Drive Dump

function and information about retrieving the data.).

Note

After you force a drive dump, do not turn off power to your LTO

standalone or you may lose the dump data.
