Installing the BMENOS0300 Module

Introduction

The BMENOS0300 Ethernet network option switch can be installed on a either a local or remote Ethernet backplane in the M580 system.

NOTE:

Mount the BMENOS0300 switch only on a BME (Ethernet) backplane. The module powers up on a BME (Ethernet) backplane, but does not power up on a BMX (X-Bus) backplane.
Schneider Electric recommends that you limit your system to two BMENOS0300 modules in an M580 rack for optimal system performance. If you install more than two BMENOS0300 modules per rack, calculate the bandwidth of your system so you do not overload the 100 Mbit/second backplane capacity.

Before Installing a Module

Before installing the module, remove the protective cap from the module connector on the rack.

Selecting a Backplane

Install the BMENOS0300 module in a single slot on one of these Ethernet backplanes:

Backplane	Description
BMEXBP04001	4-slot Ethernet backplane
BMEXBP0400(H)1	4-slot hardened Ethernet backplane
BMEXBP08001	8-slot Ethernet backplane
BMEXBP0800(H)1	8-slot hardened Ethernet backplane
BMEXBP12001, 2	12-slot Ethernet backplane
BMEXBP1200(H)1, 2	12-slot hardened Ethernet backplane
BMEXBP0602 (H)	10-slot hardened Ethernet and X Bus backplane
BMEXBP1002 (H)3	6-slot hardened Ethernet and X Bus backplane
1. In a local rack, slots 0 and 1 are reserved for the CPU. 2. In the 12-slot Ethernet backplane, slots 2, 8, 10, and 11 are X Bus only slots. 3. In the 10-slot Ethernet backplane, slots 2 and 8 are X Bus only slots.

Installing the Module on the Rack

Mount the module in a single slot on the backplane:

Step	Action
1	Turn off the power supply to the rack.
2	Remove the protective cover from the module interface on the rack.
3	a: Insert the locating pins on the bottom of the module into the corresponding slots in the rack. b: Use the locating pins as a hinge and pivot the module until it is flush with the rack. (The connector on the back of the module inserts into the Ethernet connector on the rack.)
4	Tighten the retaining screw to hold the module in place on the rack: Tightening torque: 0.4...1.5 N•m (0.30...1.10 lbf-ft)

Grounding Considerations

Follow all local and national safety codes and standards.

DANGER

HAZARD OF ELECTRIC SHOCK

If you cannot prove that the end of a shielded cable is connected to the local ground, the cable must be considered as dangerous and personal protective equipment (PPE) must be worn.

Failure to follow these instructions will result in death or serious injury.

NOTE: Refer to the ground protection information provided in the Electrical installation guide and Control Panel Technical Guide, How to protect a machine from malfunctions due to electromagnetic disturbance.

Replacing a Module

Any BMENOS0300 module on the rack can be replaced at any time with another module with compatible firmware. The replacement module obtains its configuration settings as follows:

Operating parameters (except for IP addressing settings) are set by the positions of the two rotary switches on the front of the module. When replacing a module, set the rotary switches on the replacement module to the same positions as the rotary switches on the original module.
IP address settings for the BMENOS0300 module are configured in the CPU, in its role as DHCP server. Use Control Expert to configure the Services → Address Server page of the CPU DTM and add each BMENOS0300 module to the list of DHCP clients served IP address settings by the CPU. Refer to the topic Determining the Device Name.

Hot Swap

From the system point of view, during a hot swap of the BMENOS0300 module, when the module is removed the I/O values go to fallback values. When the new module is inserted and powers up, the I/O values reset to their values before the hot swap. Refer to the topic BMENOS0300 DDDT for information about module DDDT values.
