General Information
Rear panel
Connectors
The rear panel of the printer features the host interface connectors to the printer;
it includes the following connectors:
■
Standard parallel (high-density connector)
■
SCSI high-density connector (font hard disk drive and Phaser
CopyStation only).
With the addition of a Phaser Share network card, the printer can feature either
of these connector combinations:
■
RS-232 serial and LocalTalk connectors
■
ThinNet (10base2) and Twisted Pair (10baseT) Ethernet connectors
Health LEDs
Two health LEDs indicate the status of the printer’s two CPU processors (a 29K
and a 68K processor).
■
Blinking : The printer is operating normally. Both LEDs blink
irregularly during diagnostics.
If a soft error occurs, the image processor’s 29K operates, but in a
reduced capacity. Soft failures include failure of expansion memory
SIMMs or any of the interface ports. When a soft error occurs, the
printer automatically prints a startup page on power-up listing the
error.
■
On or Off, or continuously blinking a coded error indication : A hard error
condition has occurred that would keep the image processor board
from operating. Refer to the topic “Verifying main board CPU
operation” on page 6-4 for the meaning of a coded indication.
The following figure illustrates the rear panel of the printer.
