Connection of multiple Intercom Servers GE 800
The G8-NET Card
 Multiple GE 800 Servers are connected via the Uplink and Downlink ports of the G8-NET card
 For the G8-NET card no special configuration is necessary
 A special “Discovery protocol” is used to localize the other GE 800 servers in the local network
Connection possibilities
VLAN
If the GE 800 Intercom Servers are connected via a switch, the switch must be VLAN capable.
 The following VLAN-IDs must be allowed: 1, 254 and 255
 Depending on the type of the switch these IDs must be configured
Switches with Autonegotiation
If both the Intercom Server and the switch are configured to “Autonegotiation” in certain cases the con-
nection can not be built-up.
The solution for this is a fixed configuration, e.g. “100 MBit / full duplex” (see ”
Configuration of IP-Net-
work Settings” on page 21)
Attention: For this purpose the following IP address range is reserved!
231.255.x.233 to 231.255.x.239 x...Intercom Server-ID
with switch without switch
If more than 20 servers shall be connected a switch is
required (max. 105 GE 800).
Up to 20 GE 800 can be directly connected in series via the
G8-NET card (no switch required).
Advantages: - No restrictions for IP-Subscriber cards
- Redundant connections possible (see page 16
)
- No additional costs
Disadvantages: - Increased cost / power consumption - When one GE 800 in the chain fails the rest of the chain
is disconnected as well
Restrictions: - Up to max. 105 GE 800 in LAN - Up to max. 20 GE 800
- No GE 800 fully equipped with IP-subscriber cards
