Polycom DMA 7000 System Operations Guide

Recommended Regular Maintenance
System Management
Perform the following tasks to keep your Polycom DMA system operating
trouble-free and at peak efficiency. These tasks can be done quickly and
should be run at least weekly.
Regular archive of backups
Log into the Polycom DMA system, go to System Management > Software
Management > Backup and Restore, and check for new backups. If there are
new backups, download and archive the latest one.
Every night, the Polycom DMA system determines whether its configuration
or database data have changed since the last time it performed a backup. If so,
it creates a new backup instance. For details on backups, see “Backing Up and
Restoring” on page 3-8.
General system health and capacity checks
On the Dashboard (see “Dashboard” on page 3-5), verify that no alerts are
visible and that:
• The system didn’t run out of capacity at any point in time. If the Capacity
Usage History graph shows spikes at or near the system’s maximum
capacity, it may be time to add more.
• All the expected MCUs are connected, in service, and have the expected
capacities. If there appear to be issues with an MCU, check its
configuration and status, and if necessary, call Polycom Global Services.
See “Device Management” on page 7-1.
• The Gatekeeper Status section indicates the status of the gatekeeper
connection is OK, and that the network latency between the system and
gatekeeper is within the range you would expect for your network (it may
be helpful to keep latency records for comparison over time). If it isn’t,
contact your network administrator or Polycom Global Services.
• The Network Status section shows two cluster members, one of which is
the active web host, and indicates that the public and private network
interfaces for both nodes are in a good state (upward green arrow) and
have the expected speeds:
— For Private, 1000 Mbps / Full. Errors on the private link may indicate
a problem with the Polycom DMA system. Check the crossover cable
connecting the two servers. If necessary, shut down both servers,
replace the crossover cable, and restart the servers. If that doesn’t
solve the problem, contact Polycom Global Services.
— For Public, the speed you expect for your network. Errors on the
public link may indicate an error in the interface between the Polycom
DMA system and your network. Contact your network administrator
to resolve the issue.
