It is important to note that fingers are a good option when you are using wider racks, but most 23.5"-24" wide racks do not have room for internal fingers or simply do not have enough space to use them to their full potential. When using these narrower rack solutions, you may want to look for external cable management options. External cable managers do add to the overall footprint width of your server rack or network rack, but they provide a lot of options and space for your cabling, and many also offer the option of installing rack PDUs. If using an external cable manager, it is still important to choose the correct finger configuration for your needs.
If finger cable management is not an option at all, it is important to choose the correct configuration of power strips and cable ties. Power panels for tool-free installation of PDUs are actually standard on the back of the rack, but many "off-the-shelf" racks don't take into account the way you need the back of the rack to actually function. Some of these panels simply don't allow enough room to mount PDUs and still have room for cable management. There are options in the industry that allow for two 60-amp, three-phase PDUs on one side of the rack while dedicating the power panel on the other side to cable management.
While this is more the exception than the rule, it is sometimes utilized. The most common layout is to have one PDU on each side at the rear of the cabinet and a power panel large enough to manage the cables on the remainder of the panel. This panel can be as effective as cable ties in managing cables if there are enough hole patterns in the power panel. Cable ties are a great option for cable management, but being able to use the same panel as your rack PDUs allows for fewer components, which also reduces cost.
