Central Station Startup
Different startup
Depending on the system configuration from manufacturing, the computer may be
configured as a networked central station with a shared Connex server, a warm spare
station, or a stand-alone central station. The station behavior at startup differs based on
the configuration.
Networked environment (Client / Server) considerations
In the networked environment, where there is a Connex server, it is preferred that the
Connex server be started first. The Connex server hosts the main database that all central
stations attempt to synchronize with on startup, using the Welch Allyn Connex Data
Synchronization Service. Refer to the Connex CS Server Install Guide for additional
information and startup behavior for the Connex server.
A central station configured as part of a network (client-server) model will startup with the
central station application and run by itself, but may take much longer during the startup
process if the Connex server is unreachable. The central station may also be running in a
degraded mode until the Connex server is brought online (e.g ADT services may not be
available).
Warm Spare station considerations
A system configured for Warm Spare operation is licensed and configured to contact and
synchronize its local database with that of the Connex server. The Warm Spare does not
perform any other functions than to maintain a state of readiness to be put into place as a
replacement central station when needed. Refer to
“Standard central station startup” on
page 19 below startup behavior of a Warm Spare station.
A Warm Spare is part of a network environment, with a closet sever as well. It is preferred
that the Connex server be started first. Central stations, including a warm spare should be
started after the Connex server is running. Refer to the Connex CS Server Install Guide
for additional information and startup behavior for the Connex server.
Stand-alone central station considerations
In the stand-alone central station, all required services are self contained within the CPU.
Thus, there are no other systems to consider in terms of startup order. Stand-alone
stations do not have communication ability with the facility’s EMR application.
