Shipping Information

The shipping process is fully robotic and orders are normally pulled and shipped quickly in 7 different warehouses across the US and then dropped in sealed USPS, UPS and FedEx containers for pick-up on the next business day. High volume or backordered items may have additional shipping delays. Once pulled, orders cannot be stopped, however you can return orders for refund unopened if you have changed your mind. Tracking normally is sent / updated within 48 hours of pick-up. Delivery is normally 3-10 business days after leaving the warehouse, however carrier delays may occur. Shipping may take longer in rural areas, due to carrier delay, weather or acts of God. Weekends and Holidays do not count as business days and have no pickup, movement or delivery.

Covid 19 Update — We have seen slowdowns and backlogs in package pickup, sorting, scanning and delivery by UPS, Fedex and USPS caused by worker shortages and facilities disruption due to the Covid 19 Pandemic. Some UPS and USPS hubs are no longer scanning all packages, as a result some tracking will show nothing until delivery.

The CyberPower MBP20A6, a 6-outlet (rear), 1U Maintenance Bypass Power Distribution Unit (MBP PDU), provides 100-120 VAC 20A output (derated to 16A) to 6 NEMA 5-20R receptacles. Designed for datacenters and other electrically demanding applications, the MBP20A6 allows the seamless transfer of an electrical load from UPS power to utility power for uninterrupted operation of connected equipment when performing maintenance, replacing batteries, or installing a new UPS.

A 6-foot AC cord connects to utility power; a 3.3-foot AC cord connects to the output power of the UPS. The UPS draws input power from the MBP20A6 through a dedicated NEMA 5-20R separate from the outlets for connected devices. When the switch on the front of the MBP20A6 is turned from Normal to Bypass, or from Bypass to Normal, the power that the MBP supplies to connected devices moves from one input power source to another. The LED display indicates which power source is active.

Rugged, industrial-grade metal housing protects the MBP20A6. With a 1U form factor, this PDU can be mounted in a standard server rack. Its mounting hardware also enables it to be connected to a UPS for tower configurations. The MBP20A6 is UL and RoHS compliant. A three-year limited warranty covers the PDU for three years and connected equipment for as long as you own the product.

Power Distribution
Delivers AC power to servers, equipment, and connected devices via a power distribution unit.

Maintenance Bypass
Qualified personnel can use the bypass feature to disconnect the PDU from the UPS without disrupting power to connected equipment. This feature allows connected equipment to operate seamlessly during maintenance periods, battery replacement, or UPS installation.

Manual Bypass Switch
When the Manual Bypass Switch is turned to Normal, connected equipment is supplied by UPS output. When the Manual Bypass Switch is turned to Bypass, connected equipment is supplied by utility power.

Network-Grade Plugs and Outlets
Highly durable construction ensures the efficient distribution of power in demanding IT or industrial environments to servers, equipment, and connected devices.

1U Form Factor & Mounting Hardware
The 1U form factor is made to be mounted in a standard server rack. Mounting hardware allows the PDU to be connected to a UPS for tower configurations.

Durable Metal Housing
Protects internal components and resists damage from impact or abrasions within challenging industrial environments. Also extends the life of the product.

Three-Year Limited Warranty
Covers defects in materials and workmanship in the product under normal use and conditions. See warranty for details.
