14 About Your System
Connecting External Devices
When connecting external devices to your system, follow these guidelines:
• 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.
• 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" on page 29 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 Figure 1-3. Table 1-3 lists the NIC
indicator codes.
