4.2.6 Installing Modules
Note: The HEU, OIU and IHU chassis are similar, whereas the managed modules vary depending on chassis type. The slot
locations for the control module, PSMs and expanders are the same for all chassis. Chassis slots are 100% mistake proof.

Control
Module
1
• Headend control module (HCM) – one per
system; installed in an HEU or IHU.
• Auxiliary control module (ACM) – installed in
OIUs and in any additional HEU or IHU.

PSM 1 - 2
• For installations with one PSM module – install
module in left most slot.
• For installations with two PSM modules
(redundancy) – remove blank panel from
middle slot and insert additional PSM module.
Expander 1 - 2
• For HEU – RF expander modules (RIX) are
installed in Slot 1* and Slot 14*
• For OIU – optical expander modules (OIX) are
installed in Slot 1* and Slot 14*
• For IHU – RIX module installed in Slot 1* and
OIX module installed in Slot 14*
• In installations with only one expander, the
unoccupied expander slot must be terminated
with an ETM.
IMPORTANT!
The RIX and OIX) are similar in
appearance but are NOT
INTERCHANGEABLE. Each expander
module is indicated as RIX or OIX on the
bottom of the module.
ETM 1
• Relevant if only one RIX module is installed in
the chassis.
• It is required to install the ETM in the empty RIX
slot.
RIM For HEU:
1 – 12
For IHU:
8
• In HEU - installed in Slots 2 – 12*
• In IHU – installed in RIM Slots 2-5 and can be
installed in Dual Slots 6-9.
• No need to terminate unoccupied RIM slot
(leave blank panel).
• A RIM slot can be occupied by an FRM module
(see Section
Error! Reference source not
found.
for details on FCM solution).
OIM
For OIU:
1 – 12
For IHU:
8
• In OIU - installed in OIU Slots 2 – 12*.
• In IHU – installed in OIU Slots 10-13 and can be
installed in Dual Slots 6-9
• It is not necessary to terminate unoccupied
OIM slot (leave blank panel).
• An RIM slot can also be occupied by an FMM
module (see Section
Error! Reference

for details on FCM
solution).
*Future chassis may be numbered from 0-
13, so that expander modules are
in Slots “0” and “13” and RIMs/OIMs in Slots 1-12.
Version 2.0 and higher of
management GUI display chassis numbering as “0-13”.
