Should the cable management rack be installed facing the front or the back
By having both the switch ports and the patch panel ports facing front, making changes as people move is easier than reaching into the back of the rack. It does make the cable management a bit more awkward though, since I'll have to feed all the cables from the back of the rack to the switch ports on the front, either via the side of the rack or by leaving some vertical space between the devices. And does. ocess easier, cables should be installed to enable quick access to discrete circuits. i must be disconnected to reach a piece of equipment for adjustments or other chang stly active equipment in the form of blade chassis or stacka le (aka pizza box) servers.
