Network & IT Requirements for Galaxy Hardware
This section lists requirements that pertain to System Environment, Networking and IT Requirements.
Galaxy Hardware is designed to communicate over TCP/IP connections/networks with the following stipulations.
1.
Unique, static or non-routable IP Addresses must be given to each Galaxy Panel (CPU)
and the
computers that host the GCS Communication and Event Services.
If private IP Addresses are not available, a non-routable IP Address should be used.
NOTICE: If DHCP addressing is used, and the DHCP server goes offline or changes the addresses, then
connectivity between the server and loops will be adversely affected!
2.
635 Controller: TCP/IP over LAN/WAN 10/100 Mb Ethernet/Full Duplex at port side.
3.
Specific port numbers must be available and not blocked by firewalls, switches, or routers.
System
Galaxy uses port numbers
1433, 5010, 3001, 4000, 4001, 4002,
and
4003
.
4.
Windows OS
need to set PC firewall at the Communication Server to accept the File and Print Sharing,
sqlservr.exe and sqlbrowser.exe.
5.
ONLINE VS. OFFLINE OPERATION: An access control system should have a stable network
environment
.
a.
OFFLINE OPERATION:
Controllers are designed to operate independently (offline) in a non-degraded mode of
operation when the software/database/services are offline. All “offline events” are buffered in the panel memory if
the server connection is interrupted. Offline events in the buffer are retransmitted when connections to the
Services and Database are restored.
b.
REAL-TIME EVENT MONITORING
: If your customer is providing real-time event monitoring, the panels will need
reliable/uninterrupted network connection to the SG Server/services, SG software & database. The following GCS
Services must be running/online for real-time events. GCS Client Gateway, GCS Communication Service, GCS
Event Service, GCS DBWriter Service typically are hosted on the main Communication Server. A copy of the GCS
Client Gateway must also be running on every additional monitoring station. The MSSQL Service typically runs on
the Database server (where the database is installed. This can be on the same machine (standalone install) that
serves as a communication server for small systems. On larger systems the Database server is often a separate
machine from the Communication server.
c.
Avoid running the Galaxy Hardware and Software on a network that is unstable, subject to frequent
downtime or heavy network resource demands.
Networks that provide email or public internet use can become
bogged down with traffic. Consider a dedicated network (such as one with non-routable addressing), especially if
you are using real-time event monitoring, alarm event monitoring, time & attendance, or input/output logic that
requires
global events
(panel to panel).
d.
Add all System Galaxy programs and services to any firewall, network scanning, or port blocking software.
Logging of events, and real-time monitoring can be adversely affected.
6.
LOCATION OF SERVICES AND PANELS:
•
LOCATION OF SERVICES
: Typically, the GCS Event and GCS Communication services are running on the same
computer in the same time-zone as the panels.
•
MULTIPLE EVENT SERVERS
: The system can support multiple copies of the GCS Event service but they must run on
separate computers. You cannot have multiple copies of the Event service on the same computer or vm.
•
REMOTE PANELS AND MULTIPLE TIME-ZONES
: In cases where the system is large or panels are distributed across
a wide area – (e.g. a campus setting, or remote buildings), any panels that are in a different time-zone will require a
separate copy of the Event Service running on a separate computer that is configured to use the time-zone of the
remote panels. The separate computer can be physically located in the remote time-zone, but better practice may be to
have the computer in the local time-zone. The computer serving the remote panels must be configured to the same
time-zone as the remote panels. This allows the remote events to maintain their original time-stamp.
