Connections
Both power and network connectivity are supplied to the Ethernet
Contrio controllers via their RJ-45 Ethernet ports. Power must be
supplied to the controllers via an IEEE802.3af compliant Power over
Ethernet (PoE) device. Note that PoE+ (IEEE802.3at compliant) devices
can also be used with the Contrio controllers as they are backwards
compatible with the IEEE802.3af standard. There are two types of PoE
devices which can be used to supply power to the Contrio controllers,
they are:
• An in-line IEEE802.3af compliant power injector (referred to as a
'midspan').
• An IEEE802.3af compliant PoE enabled network switch (referred to
as an 'endspan' or 'endpoint').
Typical midspan Ethernet powering devices include:
3Com
®
Single-Port 802.3at Gigabit PoE Midspan Solution - P/N: 3CNJPSE
3Com
®
Power over Ethernet Multiport Midspan Solution - P/N: 3CNJPSE24
Typical endspans (Ethernet switches) with PoE enabled ports include:
Netgear
®
ProSafe™ 24-Port Gigabit Smart Switch - P/N: GS728TP
Dell
®
PowerConnect™ 3524P 24-Port PoE Switch - P/N: 3524P
An Ethernet Contrio wall controller connects to a Soundweb London
network via its Ethernet port, either through a midspan then into the rear
of a rackmount device (e.g., BLU-806) or through a PoE compliant Ethernet
switch (endspan) using either straight-through or crossover Cat 5 cables (see
connection diagarms on next page).
If a DHCP enabled switch has been implemented on the network, the Contrio
contollers will be assigned IP addresses from the DHCP server. If no DHCP
server is present, an Auto-IP compliant IP address will be assigned. Static IP
addressing is also supported via Audio Architect. See the important note about
DHCP in the Audio Architect help file for further information.
