Quick Specs Stab-in static rails require the inner (chassis) rail members must first be attached to the sides of the system and then inserted into the outer (cabinet) members insta lled in the rack. For systems that are 2U and larger, it is recommended that two people perform this operation. Cable management arm (CMA) is a cable management accessory which connects to the rails behind the system. It allows a fully cabled system to be extended out of the rack into a service position. Strain relief bar (SRB) is a cable management solution, which in most cases, attaches to the back of the rails via the strain relief bar brackets. Cables from the back of the chassis are placed across the top of the SRB and secured by straps. Square-hole describes a 4-post rack mounting flange type where rails utilize Square holes sized according to EIA-310-D standard for mounting. Round-hole describes a 4-post rack mounting flange type where rails utilize Unthreaded-Round holes sized according to EIA-310- D standard for mounting. Threaded-hole describes a 4-post rack mounting flange type where rails utilize Threaded-round holes for mounting. Threaded round holes may require additional hardware for mounting and hardware may vary by thread type. See footnotes in table 2 for specific information on threaded-round hole mounting.
