Powering the Patchbay

Depending on the Model, the Bittree RS422 Active Data Patchbay is shipped with either one or

two power supplies. There are specific grounding and current handling requirements that the

power supplies must meet. Although you could power your patchbay with any power supply that

meets the requirements detailed in the Specifications section (section 4) of this document, Bittree

strongly recommends that you use only Bittree-supplied power supplies to power your patchbay.

To ensure uninterruptible operation and unmatched reliability, Model 422A32-D features dual,

redundant power supplies and automatic internal power switching in case of anomalous events.

Dual power indicator lights on the front panel provide complete status information on both

power supplies and the patchbay's power bus. Under normal circumstances, when both power

supplies are in good operational condition and powered-up, the patchbay draws its power from

the primary supply, "P1," which is the supply plugged into the rightmost power jack on the rear-

panel. If for some reason the primary supply stops supplying power, the patchbay automatically
