Mark the first page with a 2. If IPDS, there is another
page which you should mark 3. If you replace a Host
Card (coax or twinax) or an IPDS card, you will need to
reset the settings on these Printouts 2 and 3.
c. Reseat the host card in the lower Network Menu 1 con-
nector J6. (See "RIP Board" on page 108.) Bad connec-
tion is a common cause of these problems.
d. There is a green LED on the back of the host attachment
card just above the Coax or Twinax Connector. It is
labeled "CU". When this LED is ON, the card is receiving
and accepting POLLs from the host.
With the host cable (twinax or coax) attached and the
POST complete, observe the green CU LED.
• If the LED is on or blinking, your host attachment
card is receiving polls from the system. If you have
an IPDS card, ensure that the connection with the
Host Card is OK. Then try reseating the host attach-
ment card again. Ensure that the grounding screw is
installed. If you still have a problem, try a new IPDS
memory SIMM, a new host attachment card, or a
new IPDS card.
• If the LED is OFF, continue.
Note: The share light is only used for special circumstances. If the
Share light and the CU light are both on after POST, install a new
host attachment card.
e. Check for +5VDC on B24 of J6. If the voltage is incorrect,
replace the engine board. (See "RIP Board, Inner EMC
Shield, and Engine Board Removal" on page 91.)
f. The host attachment card receives the correct voltage,
but the printer is not communicating with the host.
• For twinax, ensure that other devices on the line are
OK.
