Resource Management
Resource Capacity
The following table describes the resource capacity allocations for theRealPresence
Collaboration Server 800s per Resource type.
GMT Offset The time zone difference between Greenwich and the MCU’s
physical location in hours and minutes.
Select the Up or Down arrows to alter the GMT Offset time on the
MCU. To enter a negative offset either type a minus in the hour box or
use the down arrow and decrease the offset below zero.
Retrieve Client Time Click this button to automatically update the MCU’s GMT Date, Time
and Offset to match that of the workstation.
Use NTP Server Select this check box to synchronize the time with up to three NTP
servers. When selected, the manual GMT Date and GMT Time
setting options are disabled. The GMT Offset fields are still active.
To implement this mode an external connection to an NTP server
must be enabled.
Enter the IP addresses of the required NTP servers in order of
precedence.
The Status field indicates whether registration with the NTP Server
failed or succeeded.
Note: TheCollaboration Server will not use a time source such as a
Windows-based, W32Time service (SNTP) time service. Only full-
featured (below Stratum 16) NTP Servers are considered sufficiently
reliable for high-accuracy timing environments.
