Daisy Chain And Network Device Limits; Using Dhcp; Using Rapid Spanning Tree Protocol (Rstp) - LG Niagara Framework MultiSITE E10 Installation Manual

INSTALLATION
Ethernet Wiring
Two RJ-45 10/100Mb Ethernet connectors are labeled PRI for primary, and SEC for secondary. Use a standard Ethernet patch cable
to an Ethernet switch. These ports are suitable for daisy-chaining MS-E10 Controllers (see image below) or for connection to either a
JACE-8000 or directly to a network. Maximum distance between nodes (network switch or controller) is 100 meters.

Daisy Chain and Network Device Limits

The maximum number of MS-E10 Controllers that are supported in daisy chain configuration is 16.
IT departments may limit the number of devices or network switches connected to a network port and may disable a port if limits are
exceeded. MS-E10 Controllers installed in daisy chain configuration off of a single port count against the limit and may trigger the switch
to disable the port. See below for an example Ethernet daisy chain layout.

Daisy Chain using Ethernet

Using DHCP

Upon first startup when IP connectivity is detected, the MS-E10 Controller initially requests an IP address via DHCP. If a DHCP ad-
dress is not found, the controller reverts to a static IP address based on its serial number. The fallback IP address is 192.168.1xx.xx,
where xx.xx is the last 4 digits of the serial number. For example, if the serial number is 123456789, the fallback IP address would be
192.168.167.89.
The default subnet mask is 255.255.0.0.
For default platform and station login credentials, see Default Login Credentials.
When MS-E10 controllers are daisy chained from a JACE-8000, you must configure the JACE-8000 port for DHCP as described in MS-
NC Startup Guide. Be sure to setup the DHCP server prior to connecting power to the MS-E10 controllers.

Using Rapid Spanning Tree Protocol (RSTP)

By default, MS-E10 Controllers are configured for loop-free daisy chain installations. In some circumstances it may be desirable to
create intentional loops in the physical network to increase fault-tolerance of the network. This requires enabling RSTP on all MS-E10
Controllers in the chain. In addition, the controllers must be connected to a network switch that also supports RSTP and has that feature
enabled. RSTP allows the MS-E10 Controllers to detect the physical layer loops and disable redundant connections until required (cable
unplugged, wire cut, etc).
NOTE: When using RSTP, always communicate with local Network IT personnel for specific guidance.
