A cabinet or rack must belong to one of the following types:

hole spacing per section 1 of ANSI/EIA-310-D-1992. See Requirements Specific to Perforated Cabinets
and Requirements Specific to Solid-Walled Cabinets.
• Standard two-post telco rack, with mounting posts that conform to English universal hole spacing per
section 1 of ANSI/EIA-310-D-1992.
