450 x 450 mm on the front side of the rack.

Single rack configuration
The following figure shows the service clearances for a single rack

Note: For safe and efficient maintenance operations, clearances should
be made as large as possible. Actual clearances for installation should be
determined after consulting with the site/facilities manager, as the
clearances can vary, depending on building conditions.
