Chapter 5
5. System Serverboard Information
This chapter includes best practice procedures to work with a node board (serverboard) in the
C2112-4G3 chassis, install memory DIMMs, PCIe expansion cards and 3.5-inch hard disk drives.
A layout and quick reference chart is included in this chapter for your reference. See “Installing
Memory” on page 33.
Note: Some software products are protected with software license keys derived from the
Media Access Control (MAC) Ethernet address. If your system requires the replacement of a node
board (serverboard), the MAC Ethernet address changes. If you are using such a product, you must
request a new license key after replacing the node board. Contact your local customer support
office:

Caution: When applicable, be sure to re-install the chassis cover after you have completed
accessing the components inside the server to ensure proper airflow and cooling for the system.
Handling the Node Board
Caution: Electrostatic discharge (ESD) can damage electrostatic-sensitive devices inside the
C2112-4G3 server. Use the ESD precautions described below when you handle printed circuit
boards or other components in the system. The following measures are generally sufficient to
protect your equipment from electric static discharge.
