Hey all. Question about standard 4 post racks. We bought some that are adjustable. Unfortunately, the posts are very flimsy, as these are some fancy cabinets with spacing on the sides for vertical patch panels, etc. We found that 2 post mounting of most Cisco devices (namely Cat 9500 1RU switches) are sagging quite bad. We're used to the new server type rails that extend to support most reasonable distances front rails to back for 4 post mounting. However, for a Cisco ASA1001, there aren't rails, but rather front and back 'ears' you use to hit both front and back posts. These would appear to not have any adjustability, the front to back post distance would seem to need to match the ears, I assume they don't adjust placement on the router much. Is there a 'standard' distance between front and back rails that devices usually adhere to? Googling didn't find an answer readily. These are 19" wide cabinets by the way. Thanks, Chuck
