Sentry 4820-XL-4
CLECs, ILECs and ISPs use the Sentry 4820 to manage
equipment in remote sites, co-location facilities and
Telco central offices. The Sentry 4820 eliminates the
need to dispatch a field service technician for manual
intervention when devices lock-up. Using a Sentry 4820,
the network operations center can quickly restart locked-up
remote internetworking devices to ensure that the network
is fully operational around the clock.

Remote Power Management of the IPM-2
individual receptacles allows a network manager to power
off, power on and reboot network devices from any location
via secure web interface, SSH, or out of band (dial-up)
session. Now the network operations center can eliminate
dispatching a field service person for manual intervention.
Using a Sentry IPM-2 they can quickly restart locked-up
remote servers & internetworking devices to ensure that
the network is fully operational around the clock.
Remote Power Control
Individual or group outlet remote power control to cycle
power and reboot any selected server(s) or other network
device(s). Use TCP/IP (HTTP, HTTPS, SSH, Telnet, SNMP)
or RS-232 to communicate with each Sentry and rectify
locked-up network devices
