module, the green
SCSI
LED on the module illuminates when SCSI
terminator power is available. If the
SCSI
LED on the transition
module flickers during SCSI bus operation, check fuse F1 on the P2
adapter board.
Note
Because any device on the SCSI bus can provide
TERMPWR
, and because the
FUS
LED monitors the status
of several voltages, the LED does not directly indicate
the condition of any single fuse. If the LED flickers or
goes out, check all the fuses (polyswitches).
In MVME761 I/O mode, the MVME2603/2604 supplies SCSI
terminator power through a polyswitch (resettable fuse) located on
the P2 adapter board.
Speaker Control
The MVME2603/2604 base board supplies a
SPEAKER_OUT
signal
to the 14-pin combined LED-mezzanine/remote-reset connector,
J1. When J1 is used as a remote reset connector with the LED
mezzanine removed, the
SPEAKER_OUT
signal can be cabled to an
external speaker to obtain a beep tone. For the pin assignments of
J1, refer to
Table 4-1
.
PM603/604 Processor
At present, you have the choice of a PowerPC 603 or a PowerPC 604
processor chip with 16MB to 256MB of ECC DRAM, 256KB of level
2 cache (L2 cache), and up to 9MB of Flash memory. The L2 cache
and 1MB of 16-bit Flash memory reside on the MVME2603/ 2604
base board. The ECC DRAM and 4MB or 8MB of additional (64-bit)
Flash memory are located on the RAM200 memory mezzanine.
