I have a SuperMicro CSE-836 3U case and it came with a MCP-290-00053-0N Rev B set of rails with the outer rail extendable length from 26.5" to 36.4"
The rack I have that it is going in is 25" so of course the rails are 1.5" too long and won’t fit the rack
I found on the Supermicro website these rails that are shorter.
Supermicro 2U-5U Rail Kit MCP-290-00058-0N with an outer rail extendable length of 19.6” to 27”
Based on what I measured on the 053 rails and can figure out, the fully closed dimension is the shortest rack they will fit and the largest number is the rail total length with all parts extended fully to locks.
Before I order them does anyone know if my thinking is correct and the 058 rails will indeed fit the 25" rack?
