Operational Tests
Function Units, BBG4 (DS3), BBG2 (MXRVO),
(all Releases) and BBG6 (STS-1E) (Release 6
through 13)
NOTE
:
This procedure should be performed on each function unit pair.
1. Verify the status of the function units by issuing the command
rtrv-
state
(RETRIEVE STATE). For Releases 7, 9, 11 and 13 enter the com-
mand
rtrv-state-eqpt
(RETRIEVE STATE EQUIPMENT).
2. Issue the command
switch-fn
(SWITCH FUNCTION UNIT). Enter
fn-a, fn-b, or fn-c
at the address prompt. Enter manual at the prior-
ity prompt. The ACTIVE LED which is presently lighted will extinguish, and
then ACTIVE LED on the other function unit will light.
3. Verify the status of the function units by issuing the command
rtrv-
state
(RETRIEVE STATE). For Releases 7, 9, 11 and 13 enter the com-
mand
rtrv-state-eqpt
(RETRIEVE STATE EQUIPMENT).
Timing Generator, BBF2/BBF2B (TGS)
1. Verify the status of the TGS circuit packs by issuing the command
rtrv-
state
(RETRIEVE STATE).
2. Issue the command
switch-sync
(SWITCH SYNCHRONIZATION).
Enter circuit pack at the sync function prompt. Enter manual at the priority
prompt. The ACTIVE LED which is presently lighted will extinguish, and the
ACTIVE LED on the other TGS will light.
