Hi. I am looking for brackets to mount my APC AP7900 switched pdu vertically. I have rack ears for horizontal mounting that came with these. I am planning a move to a colo in a half rack. I will have two of these pdu's to start but will likely need to add one more additional later on. Most equipment will have redundant power supplies. Just want to keep as much space available for servers. I am guessing I will need to inquire with the center about the brand of their racks. I will be racking my switches at both ends to save space and don't want the pdu's occupying valuable real estate.
