5.5.10.2 Replacement of Redundant Processor Module
When a redundant processor module becomes faulty, the system loses its DUAL status and
becomes single. DUAL LED’s on both processor modules will be off.
In order to regain redundancy, replace the faulty unit as soon as possible in the following
manner:
1. Do not forget to read Section 5.5.6, Safety Regulations.
2. Be careful, do not touch the primary module which may be in full operation.
3. Check that the correct program card is in position.
The system software will be loaded into the replacement processor module from the
program card.
4. Pull out the faulty module.
Grip the module firmly and extract quickly and decisively. Use both handles.
5. Check it’s revision number. The replacement module must have the same or higher
revision number. The document Release Notes included in the Delivery Binder states
which processor module can work in a redundant pair and which can not. For example,
you can not mix 8 and 16 Mbyte versions.
6. Prepare the replacement module by putting it’s start mode selector in position 2 (STOP).
7. Insert the new module carefully without reaching the rear plane contacts. Ensure that the
module slides in the guides in the subrack.
8. Push in the new module quickly and decisively.
9. This new processor module now becomes the backup.
The number display will show -3 (STOPPED).
10. Set the backup module’s start mode selector to the same position as the primary module’s.
11. Depress the ENTER button on the backup module.
12. The system will now be upgraded to DUAL. After some seconds the DUAL LED’s on
both processor modules will light up, and the backup module’s number display will read
b1.
13. Store the extracted module in an envelope of conductive plastic.
5.5.10.3 Replacement of Redundant S100 I/O Bus Extenders
This chapter describes how to replace a primary or backup DSBC 174 S100 I/O Bus Extender
and a primary or backup optical modem TC560V1/TC561V1.
In order to regain redundancy, replace the faulty unit as soon as possible as described below.
In all cases, do not forget to read Section 5.4.6 Safety Regulations.
