Toolless Vertical Mounting Rails Support 0U PDU and Cable Manager Installations
The SR42UBMDEXPND features two adjustable vertical mounting rails that support toolless button-mount 0U installation of compatible PDUs and cable managers. Each rail can accommodate two vertical PDUs or cable managers side by side, for a total of four units per enclosure cabinet. These vertical mounting rails make it easier to route power and cabling to installed rack equipment and are ideal for network switches that have side-to-side airflow and forward-facing ports.
Vented Top Panel with Cable Ports Promotes Efficient Airflow and Keeps Cables Organized
The top panel of the SR42UBMDEXPND is furnished with vents that help remove warm air from the enclosure cabinet and draw in cool air by convection. It also supports installation of standard user-supplied case fans. The top panel contains cable routing ports and is designed for quick, toolless removal with no need to disconnect cables. An open bottom facilitates cable access.
