Chapter 2 - Blade Installation and Startup
1. Turn the system power off by first powering down any expansion chassis, then power down the
Controlling Chassis-B.
2. Once the system has completed its powering down cycle (all LEDs are off), insert the USB flash drive
containing the software upgrade into the USB connector on the CCPU.
It is recommended when using a USB flash drive to install it in the CCPU with the system power
●
turned off. Certain flash drives may cause the system to reset if inserted with the power on.
Secured USB flash drives or any other type of USB flash drive that would prompt for information
●
(such as a password) or a partitioned drive cannot be used. The system will not be able to access
the system files.
3. Push in and hold the Load button.
4. Turn on the power to the Controlling Chassis-B.
5. Continue holding the Load button for approximately 10 seconds.
6. Release the Load button.
7. Wait until LEDs 2-4 are flashing on the CCPU. This could take several minutes.
8. Turn the system power.
9. Once the system has completed its powering down cycle (all LEDS are off), remove the USB flash drive.
10. Turn the system power on by first powering up any expansion chassis, then power up the Controlling
Chassis-B.

11. When the system has completed reloading the software, the Status LED will begin flashing on the
CCPU. The remaining LEDs will now be off.
To confirm the new software version has been installed, the system version number can be viewed
●
by pressing CHECK and then the HOLD key on any display keyset. This can also be confirmed in
Program 90-16-01.
The existing system software in the flash memory is replaced, but the customer data (stored in the
●
RAM) is saved.
When installing a MEMDB into a chassis which has been previously installed and programmed
without a MEMDB, in order to set the program defaults for the expanded port range (extensions:
65-512, trunks 65-200), you must load system software (as if performing a software upgrade,
page 2-99) in order to default the port entries.
With PCPro, the menu item [Tools] - [Default Un-Initialized System Data] can also be used to
default the expanded range for a PCPro database file, which can then be uploaded to the
UX5000.
