Introduction: Dell PowerVault 110T DLT VS160 Tape Drive User's Guide
Every time you turn on or reset the drive, it conducts a Power-On Self-Test (POST). This test ensures that the drive is working
properly and is ready to use. While POST is in progress, watch the front panel LEDs to see the progress and results of the test.
During POST, the following actions take place:
The LEDs illuminate one at a time, from left to right, starting with the Ready LED, next the Fault LED, and finally the Clean
LED, at approximately one second intervals
About four seconds later, the Media LED illuminates
Each LED signals a different part of the POST process
All LEDs then turn off momentarily
If a cartridge is not loaded, the Ready LED illuminates and POST is complete, the entire process taking approximately eight
seconds
If a cartridge is loaded, the Ready LED flashes while the drive mounts the cartridge, a process that can take several
minutes depending upon the position of the media in the tape path
As POST completes, the drive makes a slight buzzing noise for several seconds. This noise is normal and should be
ignored
The drive is now ready to use.
Indicator Activity During Normal Operation - Ready LED
When the PowerVault 110T DLT VS160 Tape drive is in use, the Ready LED indicates the three states detailed in
Ready LED operates independently of the other three LEDs.
Table 1. Ready LED activity and drive status
Ready LED

Off
No power to the drive
On
Power is on; no cartridge loaded or a loaded cartridge is idle with
no tape motion
Blinking
The drive is loading a cartridge or a loaded cartridge has tape
motion indicating read, write, seek, rewind, calibration, or other
cartridge activity
Indicator Activity During Normal Operation - Fault/Clean/Media LEDs
The Fault, Clean, and Media LEDs indicate the status of the drive. Note that the LEDs can indicate more than one of the indicated
operating conditions simultaneously. For example:
If cleaning is required while a DLT1 format cartridge is loaded, both the Clean and Media LEDs are on
If an internal write/read diagnostic fails as a result of a permanent write error, both the Fault and Clean LEDs blink slowly.
Table 2
describes what each front panel indicator means.
