It is so old, it still got the original APC logo on it. When I got it something inside was rattling around, turns out this was one of the relays that had vibrated off either during transit or at the previous owner. The relay pins completely snapped off.</p> <p>In this older UPS there are quite a few places that seem not to be quite as well rugged against the transformer vibrations than in newer models.</p>
