7.6 SMARTSLOT (VERSION 2) REPLACEMENT
I/O modules in a 8000 Series system may be configured as SmartSlot, allowing
modules to be replaced with another in an allocated SmartSlot. This reduces the
number of slots required in a system, because a group of modules can now have
one SmartSlot instead of a companion slot for every module. The cable required to
connect the existing and replacement module is different for input and output
modules, and so a system using SmartSlot needs at least one input SmartSlot and
one output SmartSlot. A Zone Interface Module (which can be configured as both
inputs and outputs) uses an output type SmartSlot cable. The SmartSlot cable is
fitted to the chassis at the allocated slot and has a connector to link to the slot
containing the faulty module.
SmartSlot Version 2 replacement (changeover) is effected by following the
procedure detailed below.
Bridge the faulty module and SmartSlot positions by connecting the
SmartSlot jumper connector to the exposed ‘C’ type connector on the rear of
the faulty module I/O connector.
Insert a working module of the correct type, with compatible firmware and
hardware, in the SmartSlot position. 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 normal
(primary) slot as soon as a working module is available. Insert the new
module in the primary slot and initiate a changeover by opening the ejector
levers on the SmartSlot module. DO NOT REMOVE THE SMARTSLOT
MODULE until the changeover has completed, the primary module indicates
‘active’ and the SmartSlot module indicates ‘standby’. The SmartSlot module
can now be removed.
Disconnect the SmartSlot connector.
