Network Communications Module (NCM) or a High-Speed Network Communications Module
(HS-NCM); wire and fiber versions of each are available. The wire and/or fiber versions of the
NCM or the HS-NCM can be installed in any standard option-board position (see Section 3.6
“Mounting Option Boards”); the default position is immediately to the right of the control panel.
1. Mount the NCM/HS-NCM in the selected position and screw in place firmly.
2. Connect J1 on the control panel to J3 on the NCM or J6 of the HS-NCM using the network
cable provided (P/N 75556) as described in the
NCM Installation Document
and the
HS-NCM
Installation Document
. Do not connect two NCM/HS-NCMs via NUP ports (aka NUP to
NUP).
