In Singapore, Server racks are designed and built to house servers (like HP, Dell, Lenovo and IBM) , computers, monitors, network equipment (like network switches, router, firewall , UPS, NAS, KVM switches, patch panels)
In Singapore, the most common server rack is the 42U 19 inch Server Rack Cabinet.
It is important to know the server rack’s specification or dimension as a server like IBM can only mount in a server rack with a depth of 1000mm. Besides that, you also need to know how many shelves to buy to house the unmountable network equipment.
Most Server racks do not come with any installation guide. But, as a good practice, it is good to remove all front and back door and the 2 side panels before you start mounting servers in the server rack. Some rack mount equipment may not come standard with railing kit. You may have to purchase it separately.
