3.8.1 Setting 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.
