Chapter 3: Operation - User Functions794 Paragon II switch (firmware version 4.3 or later)5 P2‐EUST/CWarning!! The maximum cable length between the reader‐enabledCIM and the Paragon switch to which it is directly connectedCANNOT exceed 500 feet (152 m). A cable longer than 500 feet mayresult in the cardʹs data loss during the transmission.If the path runs through the second‐ or even third‐tier Paragon switches,the firmware version of these upper tiers must also be 4.3 or later.Otherwise, the card reader function in the path will not be enabled. Forinformation on connecting user stations, CIMs, servers and Paragonswitches, see Basic Installation (on page 12).Notes:¾ A Paragon Main Unit is not used when in Direct Mode. In Direct Mode,only P2‐EUST/C and P2CIM‐AUSB‐C are required to activate the cardreader functionality. See User Station Direct Mode (on page 178) for moredetails.¾ P2‐HubPac does not support the card reader functionality at this time.Therefore, make sure the servers that require the card readerauthentication are not connected to the Paragon switch via P2‐HubPac.Features of P2-EUST/CThis device is an enhanced user station with a built‐in card reader.Its functions are similar to those of P2‐EUST and can work with ParagonII that has been upgraded to version 4.3 or later. The internal card readerallows users to insert their smart cards when prompted by theauthentication software installed in the servers, and deliver the necessaryauthentication data to the server. The P2‐EUST/C is compatible with allCIMs that are compatible with the standard P2‐EUST. This allows for useof the P2‐EUST/C in environments that also include servers that do notrequire the card authentication.Comparison between P2-EUST/C and P2-EUSTComponents / Functions P2-EUST/C P2-EUSTUSB Keyboard/Mouse SupportPS/2 Keyboard/Mouse SupportSun Keyboard/Mouse SupportAutomatic Skew Compensation
