While supporting the iSC-3, slide the iSC-3 into the cabinet mounting position. 

Mount the iSC-3 in the location shown in the cabinet illustration earlier in this section. If 
necessary, install side rails in the mounting position in the rack. 

Secure the iSC-3 to the cabinet mounting rails using the four mounting screws provided with 
the unit. Tighten the screws to 4.5 Nm (40 in-lb). 

Connect the RFN-provided ground cable (P/N 820-0609-10; ISC1 to GND BAR) between the 
cabinet ground bar and the grounding lug on the rear of the iSC-3, and ensure the connection 
is tight.  

Connect the RFN-provided power cable (P/N 820-0613-50; PDU-CTRL_1 to ISC1) between 
the iSC-3 power and the CTRL circuit breaker on the PDU (CTRL 1 for the primary iSC and 
CTRL 2 for the secondary iSC).  

Repeat steps 1 through 4 to mount the secondary iSC-3 (cable labels will show ISC2 instead 
of ISC1). 

Connect the two iSC-3s according to Nextel’s installation procedure. 

Using the RFN-provided coax cable (P/N 111-0001-02; BIC-ERTM 5MHz IN to ISC1 REF 
OUT-1), connect the primary iSC-3 port SITE REF OUT 1 to the BIC ERTM port 5MHz IN.  

Terminate the two remaining SITE REF OUT ports on the primary iSC-3, and terminate all 
three SITE REF OUT ports on the secondary iSC-3. 

Using the RFN-provided coax cable (P/N 111-0001-02; BIC-CRTC to ISC1 REF OUT-1), 
connect the primary iSC-3 port 10B2-1 to the BIC CRTC port 10Base2 ISC. 

Terminate the two remaining iSC-3 10B2 ports on the primary iSC-3, and terminate all three 
10B2 ports on the secondary iSC-3.
