(7) ABNORMAL SOUNDS
<Specifications>
• When the power is turned on, you may hear a low-frequency humming noise. This is caused
by transient low-frequency vibrations of the chokes for suppressing high-frequency noise or
other components and does not affect the characteristics and life span of the equipment.
(8) WARRANTY
<Specifications>
• The Manufacturer cannot guarantee for damage to data or application software caused by
hardware damage to the equipment.
• Use an operating system specified by the Manufacturer. The Manufacturer cannot guarantee
proper operation of the equipment if you use an operating system not specified by the
Manufacturer.
• This equipment is evaluated under the assumption that the hardware specified by the
Manufacturer is used. Therefore, when you install or replace hardware, use the hardware
specified by the Manufacturer. The manufacturer cannot guarantee proper operation of the
equipment if you use other hardware.
2. NETWORK
<Precautions>
• Do not send a Magic Packet™ frame at the timing when the power is about to be turned off
after OS shutdown. If you do, the equipment may restart without being turned off, or WOL
may not be possible at all. (See "3.6.2 Turning on the power using the LAN".)
<Specifications>
• Depending on the status of the network, Magic Packet™ frames can be lost. In order to avoid
this, set up the system so that Magic Packet™ frames can be propagated without loss. (See
"3.6.2 Turning on the power using the LAN".)
• Even though a network drive may be configured to be reconnected at logon, sometimes the
reconnection may fail. If this happens, log on again or use the net_use command to establish
the connection.
For information about the net use command, see the Windows® help.
• If the settings of the hub and the network adapter do not match, the performance of the
network adapter may be compromised or the network adapter may not work properly. (See
"3.7 Setting Up the LAN Interface".)
• The electric potential difference between units can generate heat. Therefore, do not use
twisted-pair Ethernet cables (such as category 5 or STP cables) for network connections other
than the ones specified in "4.4.1 Connector specifications (1) Motherboard (Standard)".
