(continued)
Step

Changing processor modes
If preparing to change a circuit pack and you need to change mode, use the
following procedure.
297-1001-536 Standard 01.03 August 1996
Action
If the test immediately fails or the
error reoccurs during the soak time,
repeat Step 6a, replacing NT6M63xx
in Step 6b. If after replacing
NT6M62xx and NT6M63xx, the
problem reappears, repeat from Step
6a, replacing NT6M64xx in Step 6b.
If the test passes, place the DPP in
the PRIME processor mode and let it
soak for 2 days.
If trouble continues, contact next level
of support.
Note:
Reseating the circuit packs listed in the TEST ACT or TEST STDBY command
clears the problem in some cases. If the error does not reoccur during the soak
time after reseating the circuit packs, then the reseating will have cleared the
problem.
Notes
NT6M63xx: EPROM card,
slot 2.
NT6M64xx: DRAM card,
slot 3.
