Redundant I/O Cards Placement
3000 Series System with I/O Cards
Redundant I/O cards may be located in any chassis; there are no restrictions.
3100 Series System with I/O Cards
Redundant Output Cards in non-safety 3100 systems have the following chassis placement
restrictions if the Output_Disable_Type field is equal to 1 in the Node Configuration file.
All Redundant Output Cards may be located in the same chassis or in a single
other redundant chassis.
There can be multiple pairs of redundant chassis, but all redundant I/O cards
must stay within the same chassis pair as the other cards in the chassis pair.
This is an example of a good redundant configuration. All Redundant I/O cards are within
two
chassis only
:
Rack0 Slot0 is redundant with Rack0 Slot1 (
OK
-Redundant cards in same Rack)
Rack0 Slot2 is redundant with
Rack1
Slot5 (
OK
-Redundant cards in one Rack and second Rack)
Rack0 Slot3 is redundant with
Rack1
Slot10 (
OK
-Redundant cards in one Rack and second Rack)
This is an example of a
bad
redundant configuration. The redundant cards are distributed over
three chassis
:
Rack0 Slot0 is redundant with Rack0 Slot1 (
OK
-Redundant cards in same Rack)
Rack0 Slot2 is redundant with
Rack1
Slot5 (
OK
-Redundant cards in one Rack and second Rack)
Rack0 Slot3 is redundant with
Rack2
Slot5 (
Not OK
-Redundant cards in one Rack and
third
Rack)
3200 Series System with I/O Cards
Redundant I/O cards may be located in any chassis; there are no restrictions.
