When space is limited and a standard server rack is simply out of the question, wall mount racks can be a good option. Instead of taking up valuable floor space for 1 or 2 servers you can place the units on the wall or even under a desk or table. These 1U and 2U wall mounts are designed to work with the original OEM rail kits so installation will require enough space to slide the rail kits out. Covers are provided for protection while still allowing for proper ventilation.
Extra brackets are available for installing multiple units such as switches and routers. These devices typically are not as deep as servers and are not equipped with full length rail kits. The brackets allow the devices to be stacked one above the other.
