CDU Technical Specifications
Sentry Switched CDU
CW-24VD/Y
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.
The Switched CDU also supports Enterprise View PDU Manager.
This gives the engineer the ability to manage a large installation of
Networked CDUs from one location, view and access multiple Smart
and Switched CDUs from a
single web interface.
> 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
:
3-Phase power; 20 or 30-Amp
power input feed options
> High Density:
Single power
input feed; 24 outlets per
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
> Enterprise View:
View and
access multiple Switched CDUs
from one 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
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.
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.
