Power up of cabinet with code load
To power up the cabinet, proceed as follows:
CAUTION
When the two LEDs of the CTU or the MCUF are flashing,
the boot code is downloading into non-volatile memory for
software upgrade. Power should not be removed, nor the
cabinet reset, until downloading has been completed, as
this will corrupt the non-volatile memory. If boot code is
corrupted, contact the Motorola Customer Network
Resolution Centre and request the boot code restoration
procedure and the appropriate boot code file.
1. Switch on the external power supply to the cabinet.
2. Turn each PSM switch to the OUTPUT ENABLE position; check that each
PSM has the active (green) LED on and the alarm (red) LED off.
3. Press the CBM circuit breaker button marked FANS. Check that each fan
module is operating correctly. Activate any fan not started by the restart
button (marked either FRONT or REAR) on the fan module.
4. Press the CBM circuit breaker button marked SURF, and if CCBs are
fitted, press the circuit breaker buttons marked CCB0 and CCB1.
