Site Planning
4-4 Site Planning and Preparation
Location The location of the Database Server is a critical first step in site planning and network
design. In general, they should be located in places inaccessible to patients and clinicians
but convenient to service and support personnel. Typically this is a wiring closet or room
specifically designed for Server equipment. The following issues should be considered
when selecting and planning locations for the Database Server.
Wiring Closets Locked wiring closets or equipment rooms are recommended locations for all active
Network components (except access points) because they can be made secure from
unauthorized access and required electrical and environmental conditions can be
maintained.
Caution In planning wiring closets, careful consideration must be given to the availability of
properly grounded electrical outlets of the correct voltage and frequency for each
device and to the environmental control of temperature and humidity. The high
density of devices in a small room can lead to large heat loads in a small space that
must be controlled.
Switches Network switches are the central communication hubs of the Clinical Network. Therefore,
they should be located at a point central to the Information Centers, Clients, and Server. In
selecting switch locations, consideration should be given to the cabling distances between
devices because cabling is a key cost and limitation of Network design. In general, switches
should be in wiring closets centrally located on the Network.
Server The Database Server is the network device most accessed by service personnel. Software
installation, system and device configuration, network maintenance and troubleshooting all
take place at the Server. Therefore, it should be located in a closet or room convenient to
service personnel and include typical workstation amenities -- chair, work surface,
bookshelf, equipment storage, lighting.
UPSs Active Clinical Network components must be on a UPS (Uninterruptible Power Supply)
to assure network operation during short power interruptions.
Warning The Database Server must
be connected to a BATTERY BACKUP outlet of the 1000
VA U P S .
The following components must
be connected to the BATTERY BACKUP outlets of a
UPS:
• Core, Edge, and Extension switches
• media translators
• workstations for all Small Database Servers, Information Centers and Clients
• Philips 2 Channel and 4 Channel Recorders
Up to 3 Clinical Network components -- switches, repeaters, media translators -- may
be connected to a single, 650VA UPS.
It is recommended
that Access Points and Repeaters also be connected to a 650 VA
UPS.
