2.1. Module Insertion and Removal
CAUTION:
The module contains static sensitive parts. static handling precautions must be observed. Specifically
ensure that exposed connector pins ARE NOT TOUCHED. Under no circumstances should the
module housing BE REMOVED.
Before installation, visually inspect the module for damage. Ensure that the module housing appears
undamaged and inspect the I/O connector at the back of the module for bent pins. If the module
appears damaged or any pins are bent, do not install the module. Do not try to straighten bent pins.
Return the module for replacement.
Ensure that the module is of the correct type.
Record the module type, revision and serial number of the module before installation.
If the module is to reside in a new chassis, or the system is being configured for the first time, ensure
that the chassis address has been set correctly before installing the modules. See Expander Chassis
Product Description (PD-8300) for further details.
To install the module:
1. Ensure that the cable assembly is correctly located.
2. Release the ejector tabs on the module using the release key. Ensure that the ejector tabs
are fully open.
3. Holding the ejectors, carefully insert the module into the intended slot.
4. Push the module fully home by pressing on the top and bottom of the module fascia.
5. Close the module ejectors, ensuring that they click into their locked position.
2.2. Module Replacement
The replacement module must be inserted in to the vacant processor slot, ensuring that the module is
correctly located and the ejector tabs are closed (see Module Insertion ands Removal). The newly
installed module will perform its power-up sequence.
Ensure that the LED indicators on the newly installed module are as follows:
LED 1 Healthy A Steady Green
LED 2 Healthy B Steady Green
LED 3 Healthy C Steady Green
If the original module has reported faults, the TMR Processor may automatically initiate the
changeover to the newly installed module. Manual changeover may be initiated either using the ejector
tabs on the original module or using commands via the diagnostic interface. To initiate the changeover
using the ejector tabs use the following sequence:
1. Release both the top and bottom ejector tabs on the original module using the ejector release
tool. DO NOT remove the module.
2. Wait until the original module indicates that it is in the standby mode of operation and the
newly installed module is in the active mode.
3. Remove the original module.
Note: Under no circumstances remove a module that is indicating ACTIVE mode. Removal of an
active module may result in modules within the chassis adopting their default (shutdown) state,
and initiate shutdown states via the application program.
