7.5 COMPANION SLOT MODULE REPLACEMENT
Each I/O module in a 8000 Series System may have a Companion Slot configured
via a double-width I/O connector, but not necessarily occupied. This enables a
faulty module to be replaced without disrupting the System.
Replacement is effected by simply inserting a working module of the same type,
with compatible firmware and hardware, in the adjacent slot. The 8000 Series
TMR Processor automatically initiates the education of the replacement module
with the appropriate data. This is indicated by the Educated LED flashing. When
education is complete, the Educated LED becomes steady green, the previously
active faulty module indicates ‘standby’ and the replacement module indicates
‘active’. Check that the remaining LEDs on the front panel of the replacement
module are healthy (refer to section 4, Module Status Indicators). The faulty module
should be removed from the System and repaired.
The 8000 Series System should have a module back in the left hand (primary) slot
as soon as a working module is available. Insert the new module in the left hand
(primary) slot and initiate a changeover by opening the ejector levers on the right
hand (companion slot) module. DO NOT REMOVE THE RIGHT HAND MODULE
until the changeover has completed, the left hand module indicates ‘active’ and the
right hand module indicates ‘standby’. The right hand module can now be removed.
