Environmental threats in your server room can cause a lot more
damage than hardware or software problems. Redundant hardware, backup
tapes, UPS battery arrays, generators and other fault-tolerance measures
can all be rendered useless if your server room overheats or floods.
Don’t ignore environmental threats – remotely manage them with an
ENVIROMUX® Server Environment Monitoring System or Intelligent Power
Distribution Control Unit via TCP/IP Ethernet protocol over CAT5 through
an RJ45 connector.
Monitor TemperatureThe most common environmental threat in
any server room or wiring closet is heat. Detect critical rises or drops
in temperature, and receive notifications when heating problems occur.
Monitor HumidityDetect abnormal humidity conditions. You define the humidity levels that are appropriate for each sensor’s environment.
Detect the Presence of WaterWhether it’s a tripped sprinkler
system or a flash flood, a server room or wiring closet is just about
the last place you want to see water. Receive notification as soon as
water makes an appearance.
Monitor Physical SecurityMonitor “dry-contact” devices including motion sensors, door sensors, vibration sensors and smoke detectors.
Control PowerRemotely reboot and control power (on/off) to servers and network devices.
