1. Connect the 9-pin connector side of the ERFCv2-OCH cable
to an available HEU/IHU RIX port and secure the connector
in place.
2. UL/DL QMA connections — connect a pair of UL/DL QMA
cables to each of the IFB UL/DL service group input ports
(i.e., SG1, SG2, and SG3).
3. Connect the single QMA connection cable to the IFB 10
MHz QMA port.
4. Perform Steps 1-2 above for second HEU if installed.
Note: Only one 10 MHz clock reference connection to the IFB is
required.

3.4.2 IFB-to-OCH Connections
The IFB output connections to the OCH are performed using
QMA/QMA cables (not provided with unit). Corning accessory
kits including appropriate cables can be ordered separately (see
Table 3.3).
Each IFB supports two optical modules (i.e., one OCH-8 or two
OCH-4 units) per service group.
Refer to Figure 3.3 and connect the IFB to the OCH as follows:
UL/DL QMA connections — connect a pair of QMA/QMA cables
from each of the service group UL and DL output ports to the
OCH optical module UL and DL link ports. IFB supports
connections to two optical modules per service group.

3.4.3 Management Connections
Connect the SC-450 front panel “LAN” port to any one of the
control module’s (HCM/ACM) four “INTERNAL” ports using the
RJ45 CAT 5 Ethernet cable, as shown in Figure 3.4.
GX management capabilities are attained through the OCH
connections to the SC-450 controller.
