Apple Mac Pro (Mid 2010) - Manual (Page 99)

99 Chapter 4 Problem, Meet Solution
You may have to click your Apple Magic Mouse once to reconnect it to your Mac Pro.
To check the battery status, slide the on/off switch to turn on the mouse. If the
indicator light doesn’t glow, you may need to change the batteries. You can check the
battery level in Mouse Preferences. Choose Apple () > System Preferences and click
Mouse. The battery level is shown in the lower-left corner.
Maximizing Ethernet Performance
Your computer performs best when the Ethernet port to which it is connected is set to
autonegotiate. Ask your network administrator to verify this setting.
Note: If you experience connection problems on your network, make sure your network
switch is set to autonegotiate, if possible. If a switch’s port is not autonegotiating, your
computer detects the appropriate speed but defaults to half-duplex mode. If the
switch’s port at the other end of the link is configured for full-duplex mode, a large
number of late events can occur on the link. If it isn’t possible to set the switch to
autonegotiate, then set the switch’s port to half-duplex. For more information, see the
documentation that came with the Ethernet switch.
Learning More, Service, and Support
