Appendix A: FLASH Upgrades

Upgrading the LCM
The LCM FLASH upgrade feature allows you to upgrade your unit with the
latest firmware available. To perform this upgrade, you will need to download
the latest FLASH firmware from IBM.
To upgrade your fi rmware, you need the following items:
• Computer running a Microsoft Windows operating system
• Available serial port (COM port) on the server
• Standard serial cable (DB-male) that connects the switch and the server
• Firmware upgrade
To upgrade fi rmware:
1. Connect the standard serial cable to a COM port on the server and to the
serial connector on the back panel of the LCM. Note which COM port you
have chosen, then turn on the switch.
2. Go to http://www.ibm.com/pc/support to access the fi rmware upgrade fi le.
Once the download is complete, navigate to the drive where you have
saved the fi rmware upgrade and unzip the fi le.
3. Double-click to run WUpDate.exe.
4. In the dialog box that displays, select the desired language and COM port.
5. Click Load.
:
ATTENTION While downloading, do not use your computer for anything else or switch
windows. The download requires constant control of your computer, and switching to
another window may cause the download to time-out. If a time-out occurs, run the WUpDate
program again.
6. Once the fi rmware is upgraded, the following message displays:
Download complete. Click Done to exit the dialog box.
7. The switch automatically restarts after the upgrade is completed.
Possible error conditions
If the download does not execute correctly, verify the following:
• Verify that the COM port is correct.
• Verify that no other program is currently using that COM port.
• Verify that no other copies of the WUpdate utility are currently running.
• Verify that a straight-through (1-to-1) serial cable is used, not a null
modem serial cable.
• Verify in Advanced Port Settings for the selected COM port that it is using
FIFO buffers and the receive buffer is set to high.
