Cisco Systems 2020 manual Installing Fantails, Required Tools and Equipment

Installing Fantails

Step 7 Repeat the procedure above if the LS2020 switch contains a second DC power tray.

Step 8 Observe the green power LED on the front of the power tray when power is applied. If the LED is not lit, check for incorrectly connected wires or problems in the DC power source.

Installing Fantails

This section explains how to mount and connect fantails in your LS2020 switch (see Figure 2-4). Fantails provide connectors for data cables on low-speed(V.35, X.21 and EIA/TIA-449) lines and T3 lines that are attached to cell line card/T3 access cards in an LS2020 switch.

If your system has no low-speed or cell line card/T3 modules, skip to the section “Attaching Data Cables.”

Required Tools and Equipment

Obtain the following equipment and tools in preparation for installing fantails:

•Fantails in the desired quantity (provided by Cisco Systems).

•Required fantail cables (provided by Cisco Systems).

•Fantail mounting screws, clip nuts, and washers (provided by Cisco Systems). If your equipment rack has metric-threaded rails, you must provide appropriate mounting screws.

•

•

•

A 5/16-inch slotted-tip screwdriver.

Adhesive labels for making appropriate notations on each fantail.

A grounding wrist strap for ESD protection during fantail installation.

Note If you are installing X.21 fantails and you plan to configure the ports as DTEs, you must obtain and install a 15-pin male-to-male gender converter on each port in order to change the female connector to a male connector. Note, however, that the gender converters are not required for X.21 ports configured as DCEs.
