Subsequent Outlet Control Commands May Fail
When the user performs an outlet control command, then immediately follows it with a second command, the second command may fail. The user must wait 5 – 10 seconds to issue a subsequent outlet control command.
Users can verify the command was successful in the web interface of the device.
Limitation on Global Device Scan Intervals
Users cannot set their global device scan settings to less than five minutes if there are more than 2026 devices discovered on their Data Center Expert Enterprise server. This restriction is not enforced on device-specific scan settings, but APC recommends that the same policy be applied to these settings.
For servers monitoring fewer than 2025 devices, it is recommended that the default 5-minute scanning rate be used for SNMP devices, and only adjusted for small subsets of critical devices.
Limitation on Surveillance Settings for Cameras
The number of cameras monitored by the Data Center Expert server, and the Camera Resolution and Target Image Capture Rate (frames per second) settings at each camera, can affect server performance. To support a large volume of surveillance data, the recommended camera settings and number of cameras for a Data Center Expert server to monitor, are:
- Basic server: A maximum of 15 cameras at 10 frames per second, 150 fps total, and a resolution of 640x480
- Standard server: A maximum of 125 cameras at 2 frames per second, 250 fps total, and a resolution of 640x480
- Enterprise server: A maximum of 250 cameras at 2 frames per second, 500 fps total, and a resolution of 640x480.
