Cabling - Olicom CrossFire 8720 Installation Manual

2. Remove the bracket covers on each side of the switch to expose the rack
mounting brackets. Access to the retaining screws is obtained by opening the
cap on the front of each bracket cover. Use the Allen key supplied with the
switch to remove the two 6 mm Allen screws. When you have removed the
screws, push the bracket cover towards the back of the switch and lift the cover
off. Keep the screws for later use.
3. Position the switch, with the mounting brackets exposed, in the rack or cabinet
and slide it up or down until the bracket holes line up with the rack holes.
Attach the chassis brackets to the rack using the Allen screws you removed
above and the nuts supplied with the switch. Close the cap again to conceal the
screws.
Table-top Mounting
The CrossFire 8720 Switch operates at a low noise level, which makes it suitable
for a work area or almost anywhere with a large enough flat surface such as a
table, desktop, or similar area.
Four self adhesive pads are supplied with the switch. The pads must be mounted in
the four recesses on the bottom of the switch. When the pads are mounted, simply
place the switch on a clear, level surface. Leave enough room around the switch
for ventilation and access to the controls and cable connectors.
Caution: Due to weight constraints, place no more than three units (or the
equivalent weight of other equipment) directly on top of another chassis. More
than three units on top of another unit may cause damage to the lower unit.

2.2.6 Cabling

When connecting devices (such as hubs, servers, personal computers, and
workstations) to the switch, remember these cabling tips:
•
Avoid stretching or bending the cables excessively.
•
Avoid routing the cables near potential sources of electromagnetic
interference, such as motorized devices and fluorescent lights.
•
Route the cables away from aisles and other areas where people walk. If
necessary, use floor cable covers or similar material to secure and protect the
cables.
•
Be sure that the cables connected to the switch are supported so that the cable
connectors are not excessively strained.
•
For 10 Base-T connections, use a Category 3 or better cables.
•
For 100 Base-TX connections, use Category 5 cables.
•
For 100 Base-FX connections, use MMF links with MT-RJ (VF45) connectors.
