UPS control

NEW POWER-MANAGEMENT SOFTWARE eases network power management with enhanced support for Linux, Windows NT/2000 and a Win32 console snap-in. Compaq Computer Corp. has enhanced its Power Management Software to ease network administrator tasks for efficiently managing network-wide power regardless of the underlying operating system. This new version allows IT managers an easy way to configure and completely control the enterprise and e-business power framework. The new additions help network administrators configure what network devices should be shut down during a power outage and in what order the devices will shut down. The Compaq Windows NT/2000 Web-enabled module offers the ability to go beyond viewing statistics and to perform all power configuration changes on the fly and in real time. From anywhere on the network, administrators can log into their intranet browser, select the http:// server name, and select the UPS link to gain password-protected access to the fully configurable, power-management options. The new software is backward compatible with all Insight Manager versions.

Power switching

ENSURE PROPER POWER to your essential network components. The TPC2562 is an AC power-distribution unit that combines true redundant input, under-voltage protection and ultra-fast switching. Designed for critical systems, the unit protects against power failures and severe brownout conditions. The TPC 2562 monitors the input voltage and automatically switches to the secondary power source when the primary source fails. Source transfer time is typically 18ms, +/- 5ms. Both lines are protected with integrated EMI/FRI protection, inline fuses and surge suppression. The front panel contains alighted on/off circuit breaker and power LEDs, which indicate low-voltage or power-good status for each source. The rear panel contains power output via eight IEC 60320, C13 outlets. The TPC 2562 is designed for a rack mount, and is only 1.75" high, 9.5" deep. The unit has detachable brackets to allow for front, rear or recessed mounting. Vertical mounting brackets are also available.

Enterprise power protection

MANAGED POWER CONDITIONING and backup is provided from a new enterprise level UPS system. The Enterprise Series UPS from Minuteman features line-interactive voltage regulation and supplies true sine wave power at all times. The main UPS control module can be mounted on a wall or in a rack, and is available in 500, 750, 1100, 1500, 2300 and 3200 VA sizes. Only 15" deep, it accommodates large plugs and power cords when installed in a cramped equipment rack. External battery packs with independent chargers can be added to provide extended runtime. The Enterprise Series UPS protects from harmful voltage surges and spikes, as well as voltage decreases or brownouts, using built-in voltage regulation technology. An expansion port allows the addition of a SNMP module, USB adapter or an interface card for monitoring multiple AS/400 compatible servers. A large acceptable input voltage range of 75 to 164 VAC reduces wear on batteries. The unit comes with a three-year parts-and-labor warranty, and a protection plan that offers up to $40,000 equipment insurance for any equipment that is properly connected to the UPS. An online utility for calculating power requirements assists administrators with installation planning.
