What is an outdoor server rack? An outdoor server rack or patch cabinet is a 19-inch cabinet that has four 19-inch mounting profiles. In these profiles, you directly attach 19-inch network equipment, such as a rack server, patch panel, switch or ups. A server rack is a specialized enclosure designed to house IT equipment. These are manufactured from galvanized steel, aluminum or stainless steel material, making them the perfect layer of security. NEMACO™ proudly offers complete thermal climate-controlled network server rack solutions designed for outdoor deployment in the harshest environmental conditions.
