Upgrading Microcode using an External SCSI II CD-ROM Drive
Use this procedure to apply a microcode update using a system upgrade
CD-ROM provided to you by IBM support. This procedure is only necessary if
the printer will not finish its boot sequence and reach a ready state. If the
printer will reach a ready state, you should use the simpler procedure
documented in "Upgrading Microcode over Ethernet or Parallel Connections"
on page B–2.
In this section you will do both a low- and high-level disk format and then
install new printer system software.
Before you begin:
• Make sure that you have an external SCSI II CD-ROM drive
• Make sure that you have a SCSI cable with which to connect the CD-ROM
drive to the SCSI port on the back of the printer. The cable:
– Should be a meter or less in length (if the cable is longer, you may need
to use a passive terminator),
– Must have a 50-pin male Centronics connector on one end and a 50-pin
male SCSI II connector on the other.
• Make sure that you have a microcode upgrade CD-ROM, provided to you by
IBM support.
• Disconnect the Ethernet cable from the printer. This prevents users from
submitting print jobs or opening utilities sessions while the upgrade is in
progress.
To upgrade microcode using a SCSI II CD-ROM drive:
1. Turn off the printer by pressing the power button on the lower right front of
the printer. When the printer is off, the power indicator light is dark.
2. Connect the SCSI II CD-ROM drive to the printer's SCSI port. As you face
the back of the printer, the SCSI port is on the far right.
3. Switch on power to the CD-ROM drive.
4. Insert the microcode upgrade CD-ROM. After a moment, the light on the
CD-ROM drive will blink.
5. When the drive light stops blinking and goes dark, turn on the printer
power.
The printer goes through POST procedures, and several status messages
are displayed. The message SCANNING BOOT DEVICE... is displayed.
Then the message PRESS MENU FOR SETUP is displayed.
6. When PRESS MENU FOR SETUP is displayed, do not press the Menu
push button. Press the left and right Cursor Position push buttons at the
same time.
7. SCANNING FILES is displayed, then:
SELECT FUNCTION
INSTALL SOFTWARE
Note: If LOADING SYSTEM... is displayed instead of
SCANNING FILES... you did not press the buttons quickly enough.
Turn the printer power off and go back to step 5.
