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.
