IBM Ethernet Switch B24X 19
The airflow of the switch is primarily port/side (front) to non-port (back) side. Air is drawn into the system
from vents on the front and front sides of the switch and expelled out the rear. The cooling characteristics
of the system allow it to be deployed in server racks featuring hot-cold aisle containment without the need
of special baffling.

Installation
The IBM Ethernet Switch B24X comes with two rack-mount brackets affixed to each side for installation
into an EIA-310D compliant rack. Screws for mounting the B24X to the rack are not included with the
switch. Allow at least 3 inches of space at the front, back, and sides of the device for proper cabling and
cooling
