Sentry Switched CDU
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.
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.
> 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
