1027145–0001 Revision E 6–34 Installing indoor hub equipment Hub installation
If a backup HT has been installed, a CCM redundancy bus cable
(HNS 1028130–0001) must be installed, as shown in figure 6-22.
This cable connects up to five IDUs. It is used for HT IDUs only.
Connect the cable from (DB–9) maintenance port to maintenance
port, as shown in figure 6-22. If the IDUs cannot be installed close
enough to each other to connect the cable, an extender cable is
available.
