Installing the Cisco 6100 Thermal Upgrade Kit
If you are using
Thick type 734A coaxial cable or equivalent, run the cable through a ferrite and clamp the ferrite
•
shut, as shown in Figure 23. Attach the ferrite as close as possible to the transmit DS3 BNC
connector (TX1) on the DS3 subtending I/O card. Tie wrap the cable directly behind the ferrite.
Figure 23
Thin type 735A coaxial cable or equivalent, run the cable through the ferrite one time, loop the
•
cable back through the ferrite, and clamp the ferrite shut, as shown in Figure 24. Attach the ferrite
as close as possible to the transmit DS3 BNC connector (TX1) on the DS3 subtending I/O card. Tie
wrap the cable directly behind the ferrite.

Step 3
Attach a ferrite as close as possible to the remaining end of the cable (see Figure 23 or Figure 24 for
ferrite installation). Tie wrap the cable directly behind the ferrite.
Step 4
Attach the end of the cable used in Step 3 to the receive DS3 BNC connector (RX) for the system I/O
card on the subtended node chassis backplane.
Step 5
Attach one end of a coaxial cable to the receive DS3 BNC connector (RX1) for the DS3 subtending
I/O card on the subtending host chassis backplane.
Attach the ferrite as close as possible to the receive DS3 BNC connector (RX1) on the DS3 subtending
Step 6
I/O card (see Figure 23 or Figure 24 for ferrite installation). Tie wrap the cable directly behind
the ferrite.
Attach a ferrite as close as possible to the remaining end of the cable (see Figure 23 or Figure 24 for
Step 7
ferrite installation). Tie wrap the cable directly behind the ferrite.

The minimum bend radius for thin type 735A coaxial cable or equivalent is
one-quarter of an inch. If the minimum bend radius exceeds one-quarter of an
inch, the cable might not work properly.
