UFI-4HSSI Back Card
Note The UFI-4HSSI back card is compatible with the UFM-U front card. It is not compatible with either the
UFM-4C or the UFM-8C front cards.
The UFI-4HSSI back card in Figure 2-29 for the UFM-U front card has four connectors. Each connector
has a tri-color status LED (see Table 2-40). Each connector corresponds to one port. For information on
configuring these ports, see the “UFM-U Configuration” section on page 2-54.
Timesaver Interfaces on the UFI-4HSSI back card are already in DCE mode (default) so you can directly connect
any DTE interface to the back card using a straight pin-to-pin HSSI standard cable.
Tip The UFI-4HSSI back card can be configured in DTE mode by using the HSSI-DTE cable to connect back
cards in DTE mode to DCE interfaces. For more information on the cables used with the UFI back cards,
see the “UFM Cabling” section on page A-32 in the Cisco IGX 8400 Series Installation Guide.
