INSTALLATION

3.8.1Setting the TPIM’s Phantom Switch and RI/RO Switch

Before you install a TPIM, set the Phantom Switch to the appropriate setting. This switch enables the port to “autowrap” if a trunk cable fails or is removed. Figure 3-11 shows the location of the Phantom Switch. If you attach a Cabletron hub to the TPIM, leave the switch at the factory default setting of 1. If you attach a Non-Cabletron device to the TPIM, use the 0 setting.

Ensure that the Ring-In/Ring-Out Switch is in the factory default RI/RO position. The TRXI does not support the Station (S) setting at this time.

Note: If the switch locations on your TPIM do not match the locations illustrated in Figure 3-11, refer to the TPIM Reference Card included with the TPIM. The TPIM Reference Card outlines the current switch locations and settings. If you have any questions, call Cabletron Systems Technical Support.
