Install the Enhanced Redundancy System

2. To begin the hardware installation, determine the location of your

modules in the system’s chassis. Plug in the communication modules,

controller and redundancy modules into the chassis, matching partners

slot for slot. See

Step 2: Install the Hardware on page 54

.

Install the following:
The first chassis and power supply, see

page 54

.

The first chassis communication modules, see

page 56

.

a.Determine the IP address for your Ethernet communication modules.

Each Ethernet communication module will have the same IP address.

Be sure to reserve the next Ethernet IP address in series for the

secondary controller to use in the case of a switchover. (For example,

192.105.1.5 and 192.105.1.6.)

b.Set both Ethernet communication modules to the same IP address.

(This rule also applies to ControlNet networks.) See

Configure the

EtherNet/IP Network on page 77

.

The first chassis controller, see

page 56

.

The first chassis redundancy module, see

page 57

.

The second chassis, power supply, communication modules, controller

and redundancy module. See

page 63

.

3. Plug in the fiber-optic communication cable to connect the redundancy

modules in both chassis. See

Step 3: Connect the Redundancy Modules

via a Fiber-optic Cable on page 63

.

4. Upgrade the redundant chassis firmware. See

Step 4: Update Redundant

Chassis Firmware on page 67

.

Update the firmware to the modules in the first chassis.
Apply power to the first chassis.
Launch ControlFLASH software and upgrade the firmware.
Upgrade the redundancy module’s firmware and verify that the status is

PRIM.

Update all remaining modules in the chassis using ControlFLASH

software.

Power off the first chassis.
Power on the second chassis.
Follow the same update process as the first chassis.
Power off the second chassis.

5. Designate the primary chassis. See

Step 5: Designate the Primary and

Secondary Chassis on page 71

.

Verify power is removed from both chassis.
Apply power to the chassis you want designated as the primary. Wait for

the status indicator to display PRIM.

Apply power to the chassis you want designated as the secondary.
