Firmware Update (From Tape)
7-2 DLT2000/DLT2500/DLT2700 Cartridge Tape Subsystem
7.2.1 Before Doing the Procedure
Before doing the procedure, remember:
__________________________Caution___________________________
During the firmware update, when the new image is actually being
programmed into the FLASH EEPROMs, a power fail (but not BUS
RESET) causes the controller module to be unusable. When doing a
firmware update, take reasonable precautions to prevent a power fail.

7.2.1.1 Updating Firmware on a Standalone System
The user can update the subsystem, even when the subsystem is not attached to a SCSI
bus, that is, a standalone system. However, to do an update, the Power-On Self-Test
(POST) must pass first, and to pass, POST needs a properly terminated bus.
The single-ended DLT2000 controller module has active terminators. Note the jumper
covering the two pins labeled on the etch: TRM PWR/TRM ENB.
The differential DLT2000 controller module does not have on-board termination.
To do a firmware update on a standalone system:
1. Find the TRM PWR/TRM ENB connector on the left side of the
DLT2000 drive (Figure 7-1, number
).
