Notification
Take whatever precaution is necessary to warn the hospital staff that the system to be
updated will be down for 20 minutes. This time is approximate and may be less or
more. The unique characteristics of each system make this impossible to predict with
100% accuracy. However, allocating 20 minutes of time is enough in most cases.
Obtaining system access
The software update is installed while the Central Station application is running and
monitoring patients. The actual downtime occurs when the CPU is rebooted for the new
software version to take affect.
The software update is installed using a Command Line Interface (CLI). Access to this
area of the system is hidden and password protected. The first level of access is through
a Command Tool window, and the second level of access is via root user. Follow the tasks
