2.6 Software Replacement/Upgrade Information
This section covers the procedures and precautions for replacing or upgrading software chip-sets of
the NION board. When removing chips, a chip puller should always be used. Never use
screwdrivers or any devices not designed for the removal of socketed chips.
Step 1. When replacing network chips, be sure to unbind the NION before replacing the chip.
Step 2. Always power down the NION.
Step 3. Using a PLCC extractor (chip puller), remove the old chip.
Step 4. When installing a new chip, proceed as follows:
For PLCC style chips, be sure to place the chip in the socket face up, matching the
bevelled corner of the chip with the bevelled corner of the socket. Then, press it gently
but firmly into the socket until it seats.
Step 5. Re-apply power to the NION.
Step 6. If the network protocol chip was replaced, refresh the NION.
