Monitoring Status Lights and Other Indicators
on the Server
The server has a number of built-in sensors that detect and report essential operating
factors, such as power, temperature, and condition of several key components. You can
monitor the server’s operation using the lights on the unit or using the remote
monitoring tools.
The server’s status lights are listed in the table below.
Working With Advanced Network Services
The Xserve G5 system provides support for advanced network services or
communication modes. Both built-in Ethernet ports and the optional Ethernet
expansion card for the server support these features. These include:
• Virtual LANs
• Jumbo Ethernet frames
