Safety-9
When turning off the power, stop the supply of all power to the Switch.
As for the AC power and AC (PoE) models with backup power supplied from the EPU,
turning off the power switch of the switch does not shut off the power to the switch.
Turn off the switches of the switch and the power supply modules to shut off the
power supplies.
As for the redundant power model with the redundant power supply units, turning off
either power switch does not shut off the power to the Switch. Turn off the switches of
all power supplies mounted on the Switch to shut off the power supplies.
Do not touch the Switch directly if you have a metal allergy.
The Switch is coated with zinc, nickel, gold, and other elements. Do not touch the
Switch directly if you have an allergic reaction to these metals. Doing so might cause
eczema or skin irritation.
Avoid looking directly at laser beams.
The Switch uses laser beams that are colorless and transparent, and invisible to the
eye. Never look directly into the optical transceiver.
Do not touch the SFP-T and SFP-T (T) during or immediately after operation.
The temperature of operating an SFP-T or SFP-T (T) can rise up to 65C after a link
is established. Do not touch it during or immediately after operation. Otherwise, you
might get burned.
To remove an SFP-T or SFP-T (T), do either of the procedures below. Otherwise, a
burn injury might result.
- When the Switch is on, block the SFP slot and wait for 5 minutes before removing
the SFP.
