Resetting the System:

2.9.10
While the system is powered up, data may be written to the S-RAM or flash memory at any time. If the UX5000
requires a system reset, you must power off the system using the power switch on the front of the Base
chassis.
This procedure will allow the system to wait until any data-writing process is completed, avoiding the
possibility of corrupting the data. If the system unexpectedly loses power while flash memory data is being
written, it could become corrupt and the system may not come up. If the S-RAM data is corrupted, the
telephones may have erratic operation.

To Perform a Cold Start:

2.9.11
System software loaded from flash memory and the customer data is erased from RAM memory.
To avoid extension and trunk renumbering if certain blades are recognized first, set the Blade Block
option using Program 90-05-01, Menu 3 for each of the blades until the system has reset. Then, unblock
the blades using Program 90-05-01, Menu 4 in the correct order to retain the proper system numbering
(Use Programs 10-03 or 90-13-03 prior to performing a cold start to record the current slot definitions.).
1.
Without a USB Flash drive installed in the CCPU, turn the system power off by first powering down any
expansion chassis, then powering down the Controlling Chassis-B.
2.
Once the system has powered down, push in and hold the Load button.
3.
Press the power button to power the system back up.
With a multi-chassis system, turn on the expansion chassis power supply, then the controlling
chassis (Chassis-B or Chassis-A) power supply.
4.
Continue holding the Load button for approximately 10 seconds.
5.
Release the Load button.
6.
When the system has completed reloading the software (approximately 2 minutes), the Status LED will
be flashing on the CCPU.

To Perform a Hot Start:

2.9.12
System software loaded from flash memory and the customer data is loaded from RAM memory.
1.
Turn the system power off by first powering down any expansion chassis, then powering down the
Controlling Chassis-B.
Once it has powered down, press the button again (first on the expansion chassis then on the controlling
chassis) to power the system back up. Wait approximately 2 minutes.
2.
When the system has completed reloading the software, the Status LED will be flashing on the CCPU.
