DRAM SIMM

J6-J13—SIMMs on the video
controller PCB
• Locate the faulty SIMM.
• When you locate the faulty SIMM, reseat
the SIMM in its socket.
• If the problem persists, clean the gold
contacts on the edge of the strip with a
pencil eraser and insert the SIMM into
another socket. If the SIMM fails in the
second location, replace it.

FU2—Ethernet fuse
• Make sure the fuse is installed.
• If the fuse is installed and the problem
persists, replace the fuse.
ETH QUIET

U16—Ethernet controller chip
• Replace the video controller PCB.

U16—Ethernet controller chip
• Replace the video controller PCB.
ETH EXT TDR
480, 481
U16—Ethernet controller chip
U46—Ethernet transceiver chip
F1—Ethernet filter (for twisted pair
Ethernet connector)
T1—Ethernet transformer (for AUI
Ethernet connector)
Checks the Ethernet network
connections.
Note:
The printer must be connected
to one of the network connectors in
order to get accurate results from this
test.
• If all other Ethernet tests pass, there may
be a problem with the network. Ask the
network administrator at the customer
site to connect a functioning printer to
that node in the network.
• If the printer does work, there may be a
problem with the printer’s Ethernet
connection and you may need to replace
the video controller board in the printer.
• If the printer doesn’t work, there may be a
problem with the network.
SCSI FUSE
600
FU1—SCSI fuse
• Make sure the fuse is installed.
• If the fuse is installed and the problem
persists, replace the fuse.
