Models 870 and 890 - Network interface controller (NIC) card

For use by authorized service providers.
Use this procedure to remove or replace a Network interface controller (NIC) card on the Models 870 and
890.
To remove a Network interface controller (NIC) card:
1. Power off the system. See Power on/off the system and logical partitions.
2. At the back of the system, remove the safety bars from the NIC card.
3. Record the connector locations of all cables attached to the NIC card for easy replacement.
Disconnect all of the cables to the NIC card.
4. Grasp the release latches located at the top and bottom of the NIC card between your thumb and
index finger, press the tabs together. Pivot the tabs and pull the card straight back.
5. If the primary NIC card is being replaced, remove all VPD cards from the old primary NIC card and
install them into the new primary NIC card. See Models 870 and 890 - VPD card.
Inspect the Network interface controller (NIC) card: You must examine the connector for any
connector damage on the removed card using the 3X magnification glass (PN 11P4747) included in the
system toolkit. If you identify a defect on the card, do not install the replacement card without contacting
your next level support for instructions.
A damaged connector on a defective card may indicate a damaged board. If the NIC card connector is
damaged, then the adjacent memory book may need to be removed to inspect the board for damage. If
the NIC card connector is damaged, then inspect the NIC board for damage.
If the removed NIC card is not damaged, carefully remove the new NIC card from the packaging. Be sure
to protect the connector and the handles when you remove the NIC card from the cardboard box or ESD
bag. Do not handle the NIC card by its connector or either of its handles. Remove the protective cover
from the connector and install it on the defective NIC card.
Notes:
v Do not stack cards on top of each other. ESD bags do not provide sufficient stacking protections.
v Do not rest a NIC card on its connector or on its handles at any time.
Once the NIC card is out of the ESD bag, examine the card VHDM connector using the 3X magnification
glass (PN 11P4747) included in the system toolkit. If any connector shows signs of damage, do not
use it.
