Veracity CAMSWITCH QUAD (Superceded by CAMSWITCH 4 PLUS) - Manual (Page 2)

Installation
Mounting holes
CAMSWITCH QUAD is fitted with two repositionable mounting
lugs to allow the unit to be secured to a wall. The
recommended mounting hole locations are shown above.
The enclosed rubber feet may be fitted if the unit is to be
located on a shelf.
Earth connection
The case should be connected to earth before any data or
power cables are connected.
The earth connection can be made via the mounting lugs.
Power supply connection
CAMSWITCH QUAD has a detatchable screw terminal connector
and will automatically configure for DC or AC supplies in the
range 10 to 40V (DC) or 20 to 28V (AC).
A Class II isolated power supply with the “double
insulated” logo (shown right) should be used.
The power supply used should be rated at 40 Watts or greater
to guarantee power availablility for all combinations of
connected devices.
Part no VQ-24V-xx (xx=country code) is a 24V DC power supply
and is recommended for use with CAMSWITCH QUAD.
The Green LED on network port 5 will light when power is
connected.
Long power cables
If the CAMSWITCH QUAD is to be located remotely from its
power supply, care should be taken to select the right cable.
Veracity can provide a spreadsheet tool for calculating the
required cable guage for given distances and loads.
Thermal considerations for high loads
CAMSWITCH QUAD can become hot in operation and adequate
space should be provided around the unit for ventilation.
Heating increases with higher loads from POE devices, and also
with lower supply voltage.
A 24 Volt supply such as VQ-24V-xx will give best performance
and should be used when the total POE load is greater than 20
Watts or when the ambient temperature exceeds 35°C (95°F).
Ethernet connection
CAMSWITCH QUAD will automatically configure its network
ports for 10Base-T or 100Base-T, half or full-duplex operation,
and either patch or crossover cables may be used.
The yellow network connector LEDs indicate network connection
status per port as follows:
LED Pattern Ethernet status
Off No link
Flashing Link good, network activity
On Link good
POE Power Management
The green network connector LEDs on ports 1 to 4 indicate
Power Over Ethernet status per port as follows:
LED Pattern POE status
Off No POE requested
4 flashes / second POE disabled: port error
1 flash / second POE disabled: power budget exceeded
On POE enabled to port
If a port error is indicated, check the network cable for open
connections or short circuits, and ensure the POE equipment is
IEEE 802.3af compliant and functioning correctly.
If the power budget has been exceeded then there is not
enough power available to safely enable all connected POE
devices.
CAMSWITCH QUAD has an available power budget of 30 Watts,
which it can allocate to POE devices according to their Power
Class. POE devices can indicate their required power as follows:
Power Class Max Device Power (approx)
0 (unclassified) 15 Watts
1 4 Watts
2 7 Watts
3 15 Watts
For example, an IP camera which draws 5 Watts will usually be
a Class 2 device, so it would “use” 7 Watts of the CAMSWITCH
QUAD's power budget when connected.
Some devices do not display a power class however, and must
be allocated the maximum 15 Watts, so only two such devices
could be enabled. The manufacturer's information for each POE
device
should therefore be checked when planning an installation.
On power-up, CAMSWITCH QUAD will enable POE to ports 1,2,3
and 4 in that order, and thereafter as devices are connected.
Operating a CAMSWITCH QUAD with any POE devices disabled
is not recommended, as a different combination of devices may
be re-enabled following a power outage or device fault. If extra
budget is required, an alternative POE supply such as Veracity's
OUTSOURCE may be used to upgrade one or more ports.
