    NetportExpress(TM) XL Print Server: Flash Memory Serial Update

    
    

    FLASH MEMORY SERIAL UPDATE

    
       NetportExpress(TM) XL print server
    
    
    
       Follow these steps to update the XL's Flash memory using a null modem
    
       serial cable connected between the XL and a workstation. A serial port
    
       update overwrites the XL's current configuration. The XL comes back on
    
       the network with the factory's default settings, just as it does with
    
       Netport(R) Manager's Factory Defaults option.
    
    
    
       The serial port update requires that you use the DOS SERFLASH.EXE
    
       command-line utility, not Netport Manager.
    
    
    
       To perform a serial port update:
    
    
    
       1.   Disconnect the XL first from the power cord, and then from the
    
       printer(s) and the network cable.
    
    
    
       2.   Carry the XL, the serial cable, the power supply, and the Intel
    
       Upgrade diskette to a workstation.
    
    
    
       3.   Turn off the power at the workstation. Attach the serial cable to
    
       the workstation's COM port but NOT to the XL's serial port. Wait until
    
       Step 5 to plug the serial cable into the XL. The XL assumes you're using
    
       COM1, unless you specify another port in Step 7.
    
    
    
       4.   Turn the workstation's power back on.
    
    
    
       5.   Plug in the XL's serial cable.
    
    
    
       6.   Insert the Intel Upgrade diskette in your workstation's 3.5-inch
    
       disk drive. Copy the files into a directory on the hard disk or into a
    
       public directory on the network. Change to the directory where the
    
       NetportExpress(TM) software is stored (for example, F:\PUBLIC\NETPORT).
    
    
    
       7.   At the DOS prompt, enter the following:
    
    
    
            SERFLASH  FileName  COMn
    
    
    
            Where FileName is  ENFLASH.SER for Ethernet or TNFLASH.SER for
    
       Token Ring and where COMn is the COM port (COM1 through COM4) that you
    
       want to use.
    
    
    
       8.   Now plug the power cable into the XL. Watch the screen for
    
       information about the status of the serial port update process.
    
    
    
       Forgotten password and the serial port update
    
    
    
       Topic in Netport Manager Help file
    
       If you set a password for an XL and forget the password, you can regain
    
       access to that XL by performing a serial port update.
    
    
    
       What happens during serial update
    
       During serial port update, the XL's Activity Light blinks to indicate it
    
       is receiving an image.  Once the entire image has been received, the
    
    
    
       Activity Light turns off while the Flash memory is updated.  Once the
    
       Flash memory is updated, the screen displays a completion message and
    
       you can plug the XL back into the network and printer(s).  For hardware
    
       installation instructions, see Chapter 2.  For configuration
    
       instructions, see chapter 3, and 4 through 7, as required for the
    
       printing protocol you want to set up.
    
    
    
       To update the NetportExpress XL server's RBL Flash Memory through its
    
       serial port, you must connect the following null modem cable from the
    
       unit's serial port, to a serial COM port of the PC:
    
    
    
       DB-9(Netport)   DB-9(PC serial port)
    
       RXD                2---------------3 TXD
    
       TXD                3---------------2 RXD
    
       GND                5---------------5 GND
    
       RTS                7---------------8 CTS
    
       CTS                8---------------7 RTS
    
    
    
       DB-9(Netport)  DB-25(PC serial port)
    
       RXD                2---------------2 TXD
    
       TXD                3---------------3 RXD
    
       GND                5---------------7 GND
    
       RTS                7---------------5 CTS
    
       CTS                8---------------4 RTS
    
    
    
       Typically PC to PC communications products such as Laplink V come with
    
       null-modem cables.
