DC Power Management

When electronic devices and network equipment are located in distant, off-site data centers or equipment cabinets, DC power is often the most practical solution for powering servers, routers, firewalls and other equipment at the remote site. The reason for prevalence of DC in cases like this is that due to the remote nature of the data center or equipment rack, AC power is not generally available. This leaves administrators with the choice of either shelling out the money to have an AC power line run to the remote equipment site, or simply relying on economical, battery-based DC power.

Choosing DC is only half the battle though. Once you’ve settled on DC, you’re still left with basically the same set of power management challenges as you would normally encounter in an AC powered environment; you still need remote access to power switching and reboot functions in order to avoid the inconvenience and expense of constant service calls and road trips to the remote site, every single time a device at the remote site needs to be rebooted, taken off line or powered up. Remote reboot and power switching functions can prove to be incredibly valuable when managing devices located in distant equipment racks or far-off data centers. When a DC powered device at a remote facility locks up and refuses to respond, an effective DC Power Management strategy can allow you to reboot remote devices or power devices on or off without a costly service call to the remote site nor an inconvenient delay while you wait for your service team to arrive on-site.

In cases like this, WTI’s RPC Series DC Power Switches can provide an ideal solution for managing DC power switching and reboot functions at remote sites, without the extra costs and delays associated with service calls to distant data centers and equipment racks. When an RPC Series DC Power Switch is part of your DC Power Management strategy, authorized tech personnel can easily control reboot and power switching functions at remote sites via Web, SSH or dial-up connection without delays or travel costs.

In addition, RPC DC Power Switches also include a comprehensive assortment of versatile monitoring and alarm features that can be employed to help you keep better track of rack temperatures, communication problems, unresponsive devices, excessive invalid access attempts and other noteworthy events at the remote site. When the RPC DC Power Switch detects conditions and events such as high rack temperatures, excessive invalid access attempts, communication problems or potentially harmful circumstances, the RPC DC Power Switch can promptly notify you via SNMP trap, email or SYSLOG message. In addition to providing notification, the RPC can also automatically switch selected DC circuits on or off according to user-defined specifications.

Although the RPC is typically used for DC Power Management in a network environment, the RPC also lends itself well to other applications as well, and can often be found providing remote DC power control for public safety equipment, Telco equipment and various radio communication elements.

In order to protect DC power switching and reboot functions from unauthorized access, RPC series DC Power Switches include a formidable array of security features, including IP address filtering, password protection and callback security (for modem communication) as well as support for popular authentication protocols such as LDAP, Kerberos, RADIUS and TACACS+.

RPC DC Power Switch models are also available with power fallback/redundancy capabilities, allowing the RPC to automatically switchover to a secondary DC power source in the event that the primary power source fails or becomes unstable. This helps to ensure constant power for mission critical DC powered equipment and essentially eliminates down time cause by factors such as failing batteries and unstable power supplies. RPC series DC Power Switches are available in 12V, 24V and 48V DC configurations, and in both 2U and 1U rack mount versions.

Managing DC powered devices located at remote sites can be both time consuming and challenging. In any case where DC powered network elements are located in distant, inaccessible locations, even a simple power reboot or DC power switching operation can lead to unexpected expenses and delays; in some cases, network services might be completely lost while tech support personnel are in transit to the remote site in order to fix the problem. WTI’s RPC series DC Power Switches are specifically designed to make life easier for network administrators and tech support personnel by providing a reliable, secure DC Power Management strategy that allows for quick, easy control power switching and reboot functions at far-off equipment sites … without the road trips, without the delays and without the extra hassle and expense.

WTI’s RPC Series DC Power Switches can provide an ideal solution for managing DC power switching and reboot functions at remote sites, without the extra costs and delays associated with service calls to distant data centers and equipment racks. When an RPC Series DC Power Switch is part of your DC Power Management strategy, authorized tech personnel can easily control reboot and power switching functions at remote sites via Web, SSH or dial-up connection without delays or travel costs.
