. MOUNT CHASSIS IN -IN RACK
Notes: • One HEU supports connections to up to four OIUs
• HEU chassis requires 4U rack height availability
• Rack nuts and screws not provided
Step 1: Determine the location of the HEU in the rack
while considering additional HEU and OIU units
and the lengths of the available ERFC cable.
Figure 1 and Figure 2 describe the optimal rack
installations for a maximum 4x4 HEU-OIU
conguration in shared and dedicated equipment
scenarios.
Step 2: Referring to Figure 3, secure the units’ rack ears to
the rack frame as follows:
• Insert two screws halfway into the rack frame.
• Position the chassis on to the screws using the
handles and the top and bottom half slots of
the rack ears.
• Secure the unit in the rack via all applicable
bracket holes using the appropriate rack nuts
and screws.

. INSTALL ALL MODULES
Note: For modules with ejectors (i.e., RIM, RIX, and
HCM/ACM) – verify that the ejectors are completely
open when inserting in dedicated slot and then
push in until the module clicks in to the backplane.
Figure 5 shows example of module type captive
screws and ejectors.
Step 1: Refer to Figure 4 for module locations. Remove
blank panel and slide in the relevant module
(chassis slots are 100 percent mistake proof):
• (One) HCM/ACM
• (One to two) PSM
• (Two) RIXs
• (One to 12) RIMs – no need to terminate
unoccupied RIM slot.
Step 2: Referring to Figure 5, secure the modules to the
backplane by:
• Closing the ejectors (for relevant modules)
• Tightening the captive screws
. GROUND HEU CHASSIS
The grounding connection is performed via a two-hole, standard
barrel grounding lug located on the HEU rear panel (see Figure 6).
Prise de terre du châssis HEU
La mise à la terre est réalisée en utilisant une cosse deux trous a
œillet standard, située à l’arriè du chassis HEU (voir Figure 6).
Required tools and components
The following additional (not supplied) tools and components
are required for connecting the system ground:
• Grounding wire — grounding wire should be sized according
to local and national installation requirements. The provided
grounding lug supports 14 AWG to 10 AWG stranded copper
(or 12 AWG to 10 AWG solid) wire conductors.
Note: The length of the grounding wire depends on the proximity
of the switch to proper grounding facilities.
• Phillips-head screwdriver
• Crimping tool — for crimping the grounding wire to the lug.
• Wire-stripping tool — for removing insulation from
grounding wire

. CONNECT RIMS TO RF SOURCE(S)
For each RIMe — connect the external RF source to the
corresponding RIMe (service specic) simplex or duplex
QMA connectors. See Figure 7.
. RIX TO OIX CONNECTIONS
Note: Each RIX module can be connected to two OIUs.
Using the appropriate length ERFC cable (according to distance
of available OIX port), connect the HEU RIX module 9-Pin
connector to the corresponding connector on the OIU OIX
module. See Figure 8.
Refer to Section 11 for schematic diagram of coax connections
in a maximum HEU-OIU conguration of 4x4 where all HEU
units are connected to all OIU units.
. RIX PILOT CLOCK CONNECTIONS
The pilot clock connections are required in both single- and
multiple-chassis congurations. Referring to Figures 9, 10, and
11, use the QMA/QMA jumper cable (PCKC47 provided with
each RIX) to connect the REF OUT and REF IN ports of each of
the RIXs in the HEU chassis.
Notes: • The REF IN and REF OUT pilot clock ports must be
connected in a closed loop as shown in Figure 10.
• Both RIX modules of each chassis must be
connected.

. MANAGEMENT CONNECTIONS
Notes: • One RJ45/RJ45 management cable
is provided with each headend unit
(i.e., HEU/OIU).
• Management connections are also described
in HCM quick installation sheet.
For HCM only — using the provided RJ45/RJ45
communication cable, connect the HCM LAN port to the
corporate LAN ( Figure 12).
HCM to ACM Management Connections — using RJ45/RJ45
communication cables perform the headend management
connections as follows:
• Referring to Figure 12 — for congurations with one
HCM and up to four ACM modules (e.g., one HEU and
four OIUs), directly connect as follows:
• Referring to Figure 13 — for congurations with one
HCM and more than four ACMs (e.g., 4x4 HEU-OIU
congurations) where there are only four available HCM
INTERNAL ports:
From (any) HCM …. To (any) ACM…
INTERNAL (TO ACM)
Port 1/2/3/4
INTERNAL (TO HCM)
Port 1/2/3/4
From (any) ACM …. To any ….
INTERNAL (TO ACM)
Port 1/2/3/4
Other available ACM
“INTERNAL (TO ACM)” port

. POWER UP
Note: Only AC power connections are described in this document. Refer to PSM-DC quick
installation sheet (CMA-365-AEN) provided with PSM-DC for wiring pinout.
Figure 14. AC Power
Supply Module LEDs
To power up the unit:
Connect PSM-AC power connector to the AC power
source using the provided AC power cable and turn
power switch on. See Figure 14 for AC connector location.
• Power input: 100-240 VAC
• Power consumption (fully loaded chassis):
200 W (maximum); 12 W per RIMe
Pour mettre l’unité sous tension:
Branchez la prise d’alimentation du PSM-AC à la source
d’alimentation secteur à l’aide du câble d’alimentation
secteur fourni et allumer l’interrupteur. Voir Figure 14
pour l’emplacement du connecteur AC.
• Alimentation: 100-240 VAC
• Consommation maximale électrique
(pour les châssis entièrement charges):
200 W ; 12 W pour RIMe
ATTENTION!
• Approved power cable – the entire length of the
power cable (or exible cord) and the insulation must
be intact. The cable must be rmly connected to both
the electrical plug and the unit itself.
• Standard plug – the use of a standard plug is
mandatory. The use of a nonstandard power plug can
cause electrocution! Also, plugging a nonstandard
plug into a standard socket that does not correspond
to the plugs’ shape can damage the socket making it
a safety hazard.
• Always disconnect all AC power sources from the unit
before servicing (i.e., maintenance).
ATTENTION!
• Câble d’alimentation qui est approuvé —la totalité
de la longueur du câble d’alimentation (ou cordon
souple) et de l’isolation doit être intact. Le câble doit
être bien connecté à la fois à la prise électrique et
l’appareil.
• Prise électrique standard — l’utilisation d’une
che standard est obligatoire. L’utilisation d’un
cordon d’alimentation non standard peut entraîner
l’électrocution! De meme, brancher une che non-
standard sur une prise standard ne correspondant
pas à la forme de de la che, peut endommager la
Prise, ce qui en fait un danger de sécurité.
• Débrancher toujours toutes les sources
d’alimentation CA de l’unité avant l’entretien.

. COAX CONNECTIONS FOR HEU-OIU X INSTALLATION CONFIGURATIONS
Figure 17 and Figure 18 illustrate the optimal installation congurations when installing four HEU and four
OIU chassis in a rack so that all HEUs can be connected to all OIUs. The optimal conguration takes into
consideration the minimum and maximum ERFC cable lengths (provided with OIXs) in either a single
19-inch rack (shared rack equipment scenario) or two separate racks (dedicated rack per operator).
Figure 17. HEU-OIU 4x4 Installation Conguration for Shared Provider Equipment
Figure 17 illustrates how each HEU is connected to each OIU in a dedicated equipment (single rack) scenario. In
Figure 17, the port numbers (1-4) indicated on each HEU correspond to the OIUs in the rack and vice versa for the
OIU port numbers. For example, Port 3 in HEU #1 indicates the connection to OIU #3, whereas Port 1 in OIU #3
indicates the connection to HEU #1.

Figure 18. HEU-OIU 4x4 Installation Conguration for Dedicated Provider Equipment
Figure 18 illustrates how each HEU is connected to each OIU in a shared equipment (dual rack) scenario. In
Figure 18, the port numbers (1-4), indicated on each HEU, correspond to the OIUs in the racks and vice versa
for the OIU port numbers. For example, Port 3 in HEU #1 indicates the connection to OIU #3, whereas Port 1
in OIU #3 indicates the connection to HEU #1.
*The ERFC cables indicated in Rack 1 are provided as an example of the lengths required for this rack conguration.
