Note on Handling
∼
For Proper Operation
∼
Observe the following notes for successful operation of the server switch unit. Use of the server
switch unit ignoring the notes will cause malfunctions or failures of the unit.
n Make sure to power off the server switch unit and disconnect the AC cord from the power outlet
before connecting or disconnecting cables.
n Check to see that the Server Online lamp goes off and unplug the power cord from the outlet
before relocating the server switch unit.
n Clean the server switch unit on a regular basis (see Chapter 3). Regular cleaning proactively
prevents various failures of the unit.
n Lightning may cause a momentary voltage drop. To prevent this problem, it is recommended
to use an uninterruptible power supply.
n Use the keyboard and mouse which you purchased as components in the NEC Express5800
server system to connect them with the server switch unit. Using any other unauthorized
keyboard and mouse cause failures of the unit as well as a malfunction of the unit.
n Do not press two or more switches simultaneously. Doing so may cause a malfunction of the
unit.
n Use only the AC cord that comes with the server switch unit. Use of an unauthorized AC cord
may cause a failure of the unit or a fire when the voltage exceeding the rated one is applied to
the unit.
n Use NEC's genuine interface cables for options. Repair of the unit due to a failure or damage
resulted from use of a third-party product will be charged even in the warranty period.
