INTRODUCTION

You can upgrade the TRXI-22 and TRXI-42 to twenty-four ports using a twelve port upgrade kit available from Cabletron Systems (Cabletron Part Number TRXI-24-UGKIT or TRXI-44-UGKIT).

The TRXI provides two additional ports for Ring In and Ring Out connections. These ports support Cabletron’s Token Ring Port Interface Modules (TPIMs). TPIMs provide full repeater functionality. They are not included with the TRXI, but can be ordered separately from Cabletron. Table 1-2 lists each TPIM.
