Connecting External Devices
When connecting external devices to your system, follow these guidelines:
l Most devices must be connected to a specific connector and device drivers must be installed before the device operates properly. (Device drivers are
normally included with your operating system software or with the device itself.) See the documentation that accompanied the device for specific
installation and configuration instructions.
l Always attach an external device while your system and the device are turned off. Next, turn on any external devices before turning on the system
(unless the documentation for the device specifies otherwise).
See Using the System Setup Program for information about enabling, disabling, and configuring I/O ports and connectors.
NIC Indicator Codes
The NIC on the back panel has an indicator that provides information on network activity and link status. See Figure1-3.
Table1-3 lists the NIC indicator codes.

When off at the same time that the link indicator is off, the NIC is
not connected to the network or the NIC is disabled in the System
