Using the Rubber Feet and Stacking Clips
The four self-adhesive rubber feet prevent your switch
from sliding around on your desk. Stick the feet to
the marked areas at each corner of the underside of
your switch.
The four stacking clips are used for neatly and
securely stacking your OfficeConnect units together.
You can stack up to four units. Small units must
be stacked above large units. To stack your units,
secure the clips on one side and then on the other.
Use the following method to secure one side:
1 Place your new unit
on a flat surface.
Your clips fit in these
positions on the side
of the unit:
2 Position a clip over
one of these holes and
push it in until it clicks
into place. Repeat this
for the other clip
position on the same
side.
3 Keeping the front of
the units aligned, rest
the bottom of the
existing unit on the
clips’ spikes. Push the
clips firmly into the
existing unit until they
click into place.
Repeat these steps to secure the other side.
To remove a clip, hold the units firmly with one hand
and hook the first finger of your other hand around
the back of the clip. Use reasonable force to pull it off.
Positioning Your OfficeConnect Switch
When installing your OfficeConnect switch, ensure:
3 It is out of direct sunlight and away from sources of
heat.
3 Cabling is away from power lines, fluorescent lighting
fixtures, and sources of electrical noise such as radios,
transmitters and broadband amplifiers.
3 Water or moisture cannot enter the case of the unit.
3 Air flow around the unit and through the vents in the
side of the case is not restricted. We recommend you
provide a minimum of 25mm (1in) clearance.
Wall Mounting the OfficeConnect Switch
There are two slots on the underside of the
OfficeConnect switch which are used for wall
mounting. You can mount the unit with the LEDs
facing upwards or downwards, to suit your needs.
When wall mounting the unit, ensure that it is within
reach of the power outlet.
You need two suitable screws. Ensure that the wall
you are going to use is smooth, flat, dry and sturdy.
Make two screw holes which are 142mm (5.6in)
apart. Use the guide at the top of this page to mark
the position of the holes. Fix the screws into the wall,
leaving their heads 3mm (0.12in) clear of the wall
surface.
Remove any connections to the unit and locate it
over the screw heads. When in line, gently push the
unit on to the wall and move it downwards to
secure. When making connections, be careful not to
push the unit up and off the wall.
CAUTION: Only wall mount single units. Do not wall
mount stacked units.
Connecting Workstations and Other
Equipment to Your Switch
WARNING: Ensure you have read the Important
Safety Information section carefully before you start.
ACHTUNG: Versichern Sie sich, daß Sie den Abschnitt
mit den wichtigen Sicherheitshinweisen gelesen
haben, bevor Sie das Gerät benutzen.
AVERTISSEMENT: Assurer que vous avez lu
soigneusement la section de L’information de Sécurité
Importante avant que vous commenciez.
CAUTION: Do not power the switch off and on
quickly. Wait about 5 seconds between power cycles.
All the ports on the switch have full and half duplex
auto-negotiation. This means that if the device
connected to a port supports auto-negotiation, the
highest compatible mode is negotiated. Full duplex
mode can only be achieved through auto-negotiation.
