Rack Requirements
This section provides the requirements for the following type of racks, assuming
an external ambient air temperature range of 32 to 104oF (0 to 40oC).
v Standard open racks
v Two-post Telco racks
The rack-mount kit enables you to install the switch into racks of varying depths.
You can use the rack-mount kit parts to position the switch with easy access to
either the port connections end of the chassis or the end of the chassis with the fan
and power supply modules. For instructions on how to install the rack-mount kit,
see the Installing the Switch section.
General Requirements for Racks
The rack must be one of the following types.
v Standard 19-inch four-post EIA rack, with mounting rails that conform to
English universal hole spacing per section 1 of ANSI/EIA-310-D-1992. See the
section entitled "Standard Open Rack Requirements."
v Standard two-post Telco rack, with mounting rails that conform to English
universal hole spacing per section 1 of ANSI/EIA-310-D-1992.
Rack Requirements for IBM SAN50C-R Chassis
The rack must also meet the following requirements.
v The minimum vertical rack space per chassis is 3.5 in. (8,8 cm).
v The width between the mounting rails must be at least 17.75 in. (45.1 cm). For
four-post EIA racks, this is the distance between the two front rails and rear
rails.
Standard Open Rack Requirements
In addition to the requirements listed in the “General Requirements for Racks”
section on page 1-1, if you are mounting the chassis in an open rack (no side
panels or doors), ensure that the rack meets the following requirements.
v The minimum width between two front-mounting rails must be two RU (rack
unit), equal to 16 inches (4 0 cm).
