Cabletron Systems TRXI-44 User Manual

Page 3-12

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.
