something heavy on top of it.
Use the supplied or a designated power cable. Using another power cable could
result in a fire or electric shock.
If the power cable is damaged so that the wires underneath the covering are visible
or cut, stop using it, and ask maintenance personnel to replace it. Discontinue using
the cable to avoid the risk of a fire or electric shock.
Make sure the power plug is free of dust, and insert the plug completely up to the
base of the prongs, so that it is not loose. Using a dusty or loosely-connected power
plug could result in a fire or electric shock.
Do not overload the power outlet.
Do not overload the power outlet by connecting multiple power plugs to the same outlet.
Overloading the outlet could result in a fire or the circuit breaker tripping due to the use of
excessive power, which can then affect other equipment.

15

Lithium battery
The Device uses a lithium battery for the real-time clock. Mishandling the battery
might cause the battery to generate heat, explode, or catch fire, resulting in a fire or
injury. Do not remove the battery from the Device, disassemble it, heat it to 100
o
C or
more, burn it, or allow it to become wet.
Cleaning
Remove dust on and around the Device regularly. In addition to possibly causing the
Device to stop, accumulated dust might result in a fire or electric shock.

19
Do not turn off the power during a software update (while the ppupdate
command is executing).
Whenthe ppupdate command is executed, the Device restarts automatically. Do not
turn off the power while the Device is restarting (wait until the STATUS LED of the
control andswitching unit changesfrom blinkinggreen to continuous green). Failureto
do so could result in a Device failure.
When the ACC LED is lit, do not remove the memory card or turn off the power.
When theACC LED of the control and switching unit is lit, the memory card is being
accessed. When a memory card is being accessed, do not remove the memory card
or turn off the power. Doing so might damage the memory card.
In addition, some commands require a certain amount of time after being entered to
finish accessing the card. Make sure that the memory card is no longer being
accessed before removing the card or turning off the power.
Handle memory cards carefully.
When inserting a memory card, do not push the card too strongly or tap it with your
fingers.
When removing a memory card, do not forcibly pull out the card if it is locked. Doing
so might damage the connector of the memory card slot.
When moving the Device, remove memory cards. Excessive stress applied on the
memory card during transfer might damage the connector part of the memory card
slot.
Do not attach any labels to a transceiver.
A label attached to the transceiver indicates that the transceiver is a standard
product from Hitachi or another manufacturer. However, such labels are attached
where they do not interfere with heat dissipation from the transceiver or the
mechanism that prevents the transceiver from coming loose from the cage.
Attaching a label to a location that interferes with these functions could cause a
malfunction in the transceiver or damage to the Device.
Ensure that voltage drops do not occur in the power facility due to an inrush
current.
Turning on the Device causes an inrush current. Ensure that voltage drops do not
occur in the power facility due to the inrush current. Voltage drops affect not only the
Device, but also the devices connected to the same electrical power equipment.
