C-5
(7) Abnormal sounds
Specifications
• When turning on the power, you might hear a low-frequency humming noise. This is caused by the transient, low-
frequency vibrations of the chokes for suppressing high-frequency noises or other components, and does not
impact the characteristics or life span of the equipment.
(8) Warranty
Specifications
• The manufacturer offers no guarantees against damage to data or application software that is caused by hardware
damage to the equipment.
• Use an operating system specified by the manufacturer. If you use an operating system not specified by the
manufacturer, proper operation of the equipment is not guaranteed.
• This equipment is evaluated under the assumption that the hardware specified by the manufacturer is used.
Therefore, when installing or replacing hardware, use the hardware specified by the manufacturer. The
manufacturer cannot guarantee proper operation of the equipment if you use other hardware.
2. Networks
Precautions
• When you receive a Magic Packet
TM
frame, verify that the standby lamp of the equipment is on. If you receive a
Magic Packet
TM
frame when the power is about to be turned off after an OS shutdown, the equipment might restart
without being turned off or Wake-on-LAN (WOL) might not function at all. (See 2.7.2 Turning on the power by
using a LAN.)
Specifications
• Depending on the status of the network, Magic Packet
TM
frames might be lost. To avoid this, set up the system so
that Magic Packet
TM
frames can be propagated without loss. (See 2.7.2 Turning on the power by using a LAN.)
• Even if a network drive is configured to reconnect at logon, reconnection is not always possible. If such cases, log
on again, or use the
net use
command to establish a connection. For details about the
net use
command, see
the Windows
®
help.
• If the settings of a hub and a network adapter do not match, the performance of the network adapter might be
compromised, or the network adapter might not work properly. (See 2.8 Setting Up the LAN Interface.)
• The electric potential difference between units can generate heat. Therefore, use a twisted-pair Ethernet cable
(such as Category 5 or STP cable) that is specified in (1) Motherboard (standard) under 5.8.1 Connector
specifications for network connections. Do not use any other cables.
