A Closer Look

The A11H has an all-black casing with metal sides and a plastic vented front panel. Behind the right side of the front panel is the battery compartment.


On the top left corner of the front is the control panel for the UPS. There are Power, Battery Test and Clear buttons, and an array of LEDs that show system status, including Load (%), Alarm and Battery Low.


The back of the unit is where all the connections are made. There are two Serial connections and two DIN connections for controlling the unit, as well as Power and Reset switches. There are six total outlets that are closely spaced together, so there is little room to add power adapters directly to the unit. However, a unit like this can be used on multiple workstations or servers, and each can be connected to the UPS with a Power Distribution Unit or "power strip." Active cooling is provided by the 70mm exhaust fan which was quiet when first turned on, but under load is was a lot more noticeable. This may not be an issue if used in a server room, as most online UPS systems would be. There are also three removable panels on the back, which can be used to add optional components like the LAN interface card or connect an external battery.


The power cable for the unit is a heavy 14AWG cable that measures about six feet in length.
