els prevent cable droop that would obscure equipment front panels and connections.
The panels may consist of a series of split ring loops similar to the wire hanger
described above, or they may be a semi-enclosed slotted raceway with a removable
cover. The styles with the cover offer the ultimate in out-of-sight cable management.
They are great for patch cords, which present the greatest challenge to neatness. The
covers are quite easy to remove, so you can get to the cords easily for new connec-
tions and moves. Covered cable raceways are also available for the vertical runs,
although the vertical pathways are not as much of a problem.
With the increased concern over tie wraps and sharp bends when using
Category 5e or 6 cabling, the gentle side of wire management really gets a boost.
Now that many in the industry have heard of actual cable failures that were cured
when tight tie wraps were cut, you can bet that installers will pay more attention to
cable management issues.
User Equipment Location
The proper location of user equipment, such as LAN hubs, is a key part of creating
a successful TR. While the TR does not necessarily contain any equipment or hubs
at all, at least in the grand scheme of structured wiring, your LAN TR almost cer-
tainly will. These hubs and other equipment must be connected to the horizontal
wiring for your workstations in order for your network to function.
The needs of LAN hubs and other active network components are a little dif-
ferent from the considerations for horizontal wiring terminations, cross-connects,
