Rear Panel - Tektronix Phaser 360 Service Manual

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), IEEE 1284C
Twisted Pair (10baseT) Ethernet connector
SCSI high-density connector (font hard disk drive only)
A special five-pin connector accommodates a service RS-232 cable
from a PC or Macintosh computer running PC-based diagnostics.
With the addition of a PhaserShare network card, the printer can feature either of
these connector combinations:
LocalTalk connector
ThinNet (100base2) and Twisted Pair (100baseT) Ethernet or
TokenRing connectors.
Note
When an Ethernet or TokenRing PhaserShare card is installed, the
printer's built-in Ethernet port is disabled.
Health LEDs
Two health LEDs indicate the status of the printer's CPU functions: PostScript
processing and print engine control.
Blinking : The printer is operating normally. Both LEDs blink
irregularly during diagnostics.
If a soft error occurs, image processing occurs, 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 listing the error.
On or Off, or blinking a coded error indication : A hard error condition has
occurred that would keep the image processor board from operating.
Refer to the Chapter 6 topic "Verifying main board CPU operation" on
page 6-3 for the meaning of a coded indication.
