Caution!
When part of a PRAESENSA system is powered down, including the DHCP‑server, while the
rest of the system remains in operation, then, upon restart of the DHCP‑server, some
DHCP‑servers may assign an IP‑address to a restarting PRAESENSA device that is already in
use by one of the devices in operation. This will result in unexpected behavior of the system
and requires a power cycle of the whole system, to renew all IP‑addresses. Also the
DHCP‑server function of the PRA-ES8P2S switch is suffering from this behavior; therefore this
function is disabled by default and it is advised not to enable and use it.
Rapid Spanning Tree Protocol (RSTP) support
The PRAESENSA system supports redundant network cabling when Rapid Spanning Tree
Protocol (RSTP) is
enabled . By default RSTP is enabled because a PRAESENSA system is, for
emergency standards compliance, mandatory installed in a redundant network. IMPORTANT:
When having RSTP disabled , and a redundant network installed, the system will not function .
See the PRAESENSA installation manual.
Notice!
How to set up PRAESENSA in an Ethernet network is outside the scope of this manual. To
prevent network failures in both PRAESENSA and in a Ethernet network where RSTP is not
supported or allowed, contact your local IT representative in case PRAESENSA needs to be
part of the external/building Ethernet network.
3.3.2 LAN settings
The Local Area Network (LAN) settings can influence the ability to fully access the PRAESENSA
system. Because of security considerations PRAESENSA only accepts one connection at the
same time.
To do so:
1.
If not already done, Run the “SetupOMNEOFirmwareUploadToolBundle(64).exe” software
which will install the Domain Name System Service Discovery (DNS‑SD) service
automatically on the configuration PC.
–
See
(Mandatory) software, page 16.
2. Before the DNS‑SD is activated, make sure that the LAN‑setting of the configuration PC is
set to “Automatically detect settings”. To do so:
–
Windows version < 10 . Windows Start > Control Panel > Internet Options >
Connections > LAN Settings > check “Automatically detect settings”.
– Windows version 10 : Windows Start > Control Panel > Network and Internet >
Internet Options > Connections > LAN Settings > check “Automatically detect
settings”.
