6. INSTALLATION: Cabling & Mounting
6-1 Notes on Cabling
Cable Routing & Clamping
- Take care not to deform the profile of the cable by clamping it too tightly or by
bending it too sharply.
- Do not slack the cable. In the passage, it is a good practice to clamp the cable
with shorter interval or pass it through a pipe to prevent the cable from being
caught by some object. Avoid the places where damage of the cable is
anticipated, or protect the cable by passing it through a pipe.
- Take care so that the cable may not be caught by the cable cover of the access
point.
- To prevent interference by induction, separate the cable from power cables or the
ones which handle large power:
POWER LINE REQUIREMENT
Low-voltage Line (below 600 V) Separate 30 cm or more
High-voltage Line (up to 7000 V) Separate 1 m or more
To install the cable in shorter distance from the power lines, pass it through a
metallic pipe which is grounded sufficiently.
Static Discharge
If the unit or cable is installed at the place where objects (human body, cargo boxes,
etc.) touch it frequently, the unit may sometimes malfunction due to static discharge
from it. In such a case, take the following measures:
- Use STP (Shielded Twisted Pair) cable.
- When you use STP cable, use the STP-version of the hub, too. Also, do not
forget to ground the body of the hub.
Of course, you may usually use UTP (Unshielded Twisted Pair) cable rather than
STP cable.
Power Supply
Power is fed through the Ethernet cable connected to the LAN/PoE Port
(IEEE802.3af compliant). Stick a label to the power supply-end of the Ethernet
cable so that you may identify which access point is connected to. (These
measures are helpful when turning on-off specific access points.)
