Sentry 4835-XL-4
Sentry 4835-XL-4
Sentry™ 4835 Remote Power Manager & Power Distribution
Unit minimizes the impact of locked-up routers, DSLAMs,
ATM switches and other internetworking devices on business-critical
networks. CLECs, ILECs and ISPs use the Sentry 4835
to manage equipment in remote sites, co-location facilities
and Telco central offices. The Sentry 4835 eliminates
the need to dispatch a field service technician for
manual intervention when devices lock-up. Using a Sentry
4835, the network operations center can quickly restart
locked-up remote internetworking devices to ensure that
the network is fully operational around the clock.
Sentry 4835-XL-4 Key Features & Benefits
Sentry
4835-XL-4 Remote Outlet Grouping & Control:
Assign outlets
to a group for control of dual-power supply servers
and other gear with a single command. Create an
unlimited number of groups with any combination of outlets
associated to each group.
Sentry
4835-XL-4 HTTP/HTTPs Web Configuration & Control:
Use the Sentry Web interface to configure each unit,
including network settings, outlet naming & grouping,
SNMP traps for environmental & power thresholds and
firmware updates. Also use the Web interface to control
individual or group outlets and monitor environmental
conditions. SSL security provides a secure HTTPs connection.
Sentry
4835-XL-4 SNMP Management: The Sentry
family of products supports the Simple Network Management
Protocol (SNMP). This allows network management systems
to use SNMP requests to retrieve information and control
power for the individual outlets. The Sentry includes
an SNMP v1 agent supporting standard MIB I and MIB II
objects. A private enterprise MIB extension (Sentry3
MIB) is also supported to provide remote power control.
Sentry
4835-XL-4 SNMP Traps for Event Notification:
SNMP traps can be generated for various events, including
Input Current Load Thresholds (min & max), Temperature
Thresholds (min & max), Humidity Thresholds (min & max),
water indication, closed contacts (cabinet doors open/close),
as well as notification of any time an outlet status
is changed (on/off).
Sentry
4835-XL-4 Rack-Mount Enclosure: 1U and
2U "horizontal" rack-mount enclosures are 17" wide and
include standard mounting brackets for 19" cabinet rails.
23" brackets also available.
Sentry
4835-XL-4 Authentication: 16-character
Username & Password required for network administrators
& user accounts. Multiple user accounts can be established
with access rights only to designated outlets.
Sentry
4835-XL-4 Telnet Management: Telnet
is a user command and an underlying TCP/IP protocol
for accessing remote computers
Sentry
4835-XL-4 Optional Secure Global Modem:
An optional field-replaceable global secure modem
that supports 56Kbps operation, Call-Back Security,
and remote configuration. It is approved for use in
48 countries. Additionally, the internal modem option
and Pass-Thru Port Access can eliminate multiple modems
and dial-up lines and the need for an expensive terminal
server. (Available in Sentry "horizontal" rack-mount
models.)
Sentry
4835-XL-4 Multiple Concurrent Users:
Multiple concurrent users allows several users to be
logged into a Sentry at the same time. In this way,
different users, with access rights to only their equipment,
can reboot their device(s) when they need to, without
waiting for another user to log out of the Sentry unit.
Sentry
4835-XL-4 Remote Individual Outlet control:
Reduce Mean Time to Repair (MTTR) of a failing server
by controlling individual power outlet receptacles to
reboot any selected server or other device.
Sentry
4835-XL-4 Always-On Outlets: Outlets are powered-on
in their default state. User action is required to perform
a power-off or reboot to change the status of each power
outlet receptacle's relay.
Sentry
4835-XL-4 Input Current Monitor Per Outlet:
Input Current Monitor Per Outlet
Sentry
4835-XL-4 NEBS Compliant: Meets NEBS
Level One and Level Three requirements for co-location
in a BellCore (Telcordia) central office.
Sentry
4835-XL-4 Circuit Breaker-protected Outlets:
Power outlet protection provided by thermal circuit
breaker.
Sentry
4835-XL-4 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.
