Do not repair, remodel or disassemble
Do not attempt to repair, remodel or disassemble the equipment on your
own, except for performing expansion work in accordance with the
instructions in this manual. Work performed by unqualified persons can
lead to an electric shock, fire, or burns. Especially it is hazardous if you
touch areas inside the high-voltage power module.
High temperature at a power supply module
When a power supply module is in operation, the cover and handle get
hot. Be careful when replacing a failed module. You can get burned.
High temperature at the 10GBASE-R transceiver
The 10GBASE-R transceiver in the 10Gb LAN switch module gets hot in
operation. To remove the transceiver, therefore, allow at least
approximately 5 minutes after the power supply for the 10Gb LAN switch
module is turned off from the management module. Failure to do so can
cause you to get burned.
Adding and replacing parts
The cover and internal parts are hot immediately after the power is
turned off. You must wait for about 30 minutes before adding or removing
internal parts unless otherwise specified in this manual. If not, the hot
equipment causes you to get burned.
Laser beam
¢
On this product, a Class 1 laser product is installed. Do not look
directly at the laser beam. Do not look at the laser beam using an
optical instrument.
¢
Under the laser module cover, a laser beam is being emitted. Do not
remove the cover of an unused board.
Contact with metal edges
When moving the equipment or adding parts, take care not to hurt
yourself on the metal or plastic edges. You can wear cotton gloves to
protect your hands.
