Server Technology CDUCW-24V4 User Manual

Key Features

> High Density: Single-power

input feed; 24 outlets per
enclosure

> High Power Distribution:

Three-Phase 400V power; 16 or

32-Amp power input feed
options with 230V output

> 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 web
browser or serial screen.

> IP Access & Security: Web

interface, SSL, SSH, Telnet, SNMP,
FTP, SNTP, Syslog, LDAP, LDAPS,
TACACS and RS-232 access

> SNMP Traps: Provide automated

alerts for power and
environmental conditions

> Power-up Sequencing: Prevent

an in-rush power overload

> Environmental Monitoring:

Each Switched CDU supports two
external temperature & humidity
probes and reports conditions
thru the user interface without
the need for additional IP
addresses

> Add an Expansion Module:

Daisy chain the Switched CDU
Expansion Module (CW/CX) for
power monitoring of separate
power circuits from a single IP
address

Sentry Switched CDU

CW-24V4

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 or email based 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 UL 60950-1 requirement
for Branch Circuit Protections
> UL-489 rated circuit breakers

Input Current Monitoring

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 10’ (3m) probes.
Each of these probes measure both temperature and
humidity. Receive SNMP-based alerts or email notifications
when conditions exceed defined thresholds.
