Sentry : Solutions for the Data Center Equipment Cabinet
Sentry Switched CDU
Key Features
> Remote Power Management:
Power cycle individual power
outlets, or groups of power
outlets, to remotely reboot
servers and network devices,
anywhere in the world. Or,
power-off unused power
receptacles
> High Power Distribution: 120V,
208V, or 230V power; 20 or
30-Amp power input feed
options
> High Density: Single power
input feed; 8 outlets per 1U
enclosure
> IP Access & Security: Web
interface, SSL, SSH, Telnet, SNMP,
FTP, SNTP, Syslog, LDAP, LDAPS,
TACACS and RS-232 access
> Add an Expansion Module:
Daisy chain the Switched CDU
Expansion Module (CW/CX) for
power management of separate
power circuits from a single IP
address
> Environmental Monitoring:
Each Switched CDU supports two
temperature & humidity probes
and reports conditions thru the
Web interface
> SNMP Traps: Provide automated
alerts for power and
environmental conditions
> Input Current Monitor:
Precisely measure the aggregate
current draw (in amps) on each
power circuit. On-site
verification of the input current
with the LED digital display.
Remote verification via browser
or serial screen.
> Power-up Sequencing: Prevent
an in-rush power overload
CW-8H
High-Density Power Distribution
The Switched CDU’s combine remote configuration and management with power
distribution and power and environmental monitoring. Reboot a single or
dual-power server with one command. Receive SNMP-based alerts and email alerts
when power or environmental conditions exceed thresholds. Assign users specific
access rights to designated outlets or groups.
Only the Switched CDU products provide the flexibility needed for all data centers
and remote sites, including power requirements for high-amp, high voltage; UL
60950-1 branch circuit protection; SSL & SSH security; and SNMP-based input current
monitoring.
Additional Benefits:
Branch Circuit Protection
The Sentry CDU Family meets the new UL 60950-1
requirement for branch circuit protection.
Attention! The Sentry CDU products meet the above criteria by
providing overcurrent protection with UL-listed Bussman SC fuses for
each branch circuit. The CW-8H contains fuses within the enclosure.
Input Current Monitoring
The CDU’s exclusive True RMS current monitoring is critical
to preventing overloads in high-density computing
environments. LED digital displays on the CDU enclosure
report the input current of each phase or branch circuit.
Temperature and Humidity
The Switched CDU supports two external probes. Each of
these probes measure both temperature and humidity.
Receive SNMP-based alert notifications when conditions
exceed defined thresholds.
