TAPE (Tape Unit) [G3iV1.1-286]
NOTE:
Alarms on the TAPE, PROCR, and PR-MAINT MOs are indicated by the red
LED on the Processor circuit pack.
The Tape Unit consists of a Wangtek FAD3500 series tape drive mounted on the
TN774 Tape Drive circuit pack, which is controlled by the TN773 Processor
circuit pack. For tape controller functions, the processor uses memory on the
TN770 Memory circuit pack.
The Tape Unit is used to:
■ Boot the system
■ Save or load translations and announcements
■ Save the Error Logs
■ Save core dumps
There are two versions of the test tape system technician command that can be
used to initiate maintenance tests on the Tape Unit: one for Standard systems
and one for High and Critical Reliability systems. In a Standard system, the
command line entry to test the TAPE (Tape) MO is test tape [short/long] [repeat
n/clear]. In a High or Critical Reliability Option system, the command line entry to
test the TAPE (Tape) MO is test tape [short/long] [a/b] [repeat n/clear].
In a High or Critical Reliability system, if an alarm is raised against the Tape Unit,
the alarm also indicates the carrier (either 1A or 1B), depending on which SPE
has the problem.
NOTE:
CLEANING THE TAPE DRIVE HEAD IS VERY IMPORTANT because a tape
drive head with abrasive particles can permanently damage a new tape. In
1. This alarm occurs only at power-up time or on a Reset System 3, 4, or 5 when
the system cannot load all translations from tape. Refer to the footnote
associated with Error Type 3329 in the
"Hardware Error Log Entries and "Test to
Clear Values"
section.
