Connecting UFM Cabling

For important details on standard cables and Y-cables for the UFI back cards, refer to the cabling description in the UFM-U section of the Cisco IGX 8400 Series Reference.

Take the following steps after you have inserted the cards according to the information on installing cards in the section titled “Preparing the Cards” page 1. Connect the cables as follows:

Step 1 For the UFM-U/UFI card sets, make sure the cables are the correct DCE or DTE versions. For V.35 and X.21 connectors where both ports are to be used with two-port versions of the cable, the cable is either DCE or DTE. (You must specify both ports to be either DCE or DTE when you configure the port with the cnffrport command.)

Step 2 Bring each cable through the opening at the top or bottom of the cabinet (if applicable) and along the back of the unit. If necessary, use the cable manager to help route the cables.

Step 3 Add optional Y-cables as necessary.

Step 4 Secure the cables to the connectors on the back cards that mate with the correct front card. If the front card is a UFM-4C, use only the first four lines. If you install Y-cable redundancy on a UFI-4HSSI card, only Port 1 is configurable for redundancy.

Step 5 Record the slot number of each line for configuration purposes after you install the hardware.

Setting Up Frame Relay Ports and Connections (UFM)

This section outlines the steps for setting up and deleting Frame Relay ports, adding connections, and bundling connections. If a port has multiple PVCs, you can optionally bundle the connections. Bundling facilitates network meshing. You can specify connection bundling during parameter specification in the Add Connection ( addcon) command: if you press Return without specifying a DLCI during port specification, the system prompts for bundling information. See the “Frame Relay Connections” chapter in the Cisco WAN Switching Command Reference for details.

Use either a Cisco WAN Manager workstation an IGX control terminal to do the following tasks. For detailed command descriptions, see the Cisco WAN Switching Command Reference.

Step 1 If necessary, use the dspcds command to verify the correct UFI back card and UFM front card. (Use the vt command to access other nodes.) The dspcds output shows any mismatch between firmware on the front card and firmware on the back card.

Step 2 If the card is a UFM-C, “up” (or activate) each line with the Up Line ( upln) command. The range of lines for a UFM-4C is 1 to 4. The range of lines for a UFM-8C is 1 to 8.

A UFM-U does not require activation with the upln command.

Step 3 If the card is a UFM-C, assign logical Frame Relay ports to individual physical lines by using the addfrport command. A UFM-U does not require addfrport. An optional command you can use for a UFM-C either before or after addfrport is the Configure Line command (cnfln ) command. Note that if you use cnfln to assign a DS0 to carry signaling, you cannot subsequently assign that DS0 for user-data with addfrport.

Step 4 If the card is a UFM-U, use the cnfmode command to configure the mode of the card if you do not use the default of mode 1. You must understand the ramifications of this step before you use cnfmode. If you do not understand the modes of the UFM-U, refer to the UFM-U description in the Cisco IGX 8400 Series Reference.
