4.4 Electrical/mechanical hazards prevention

DANGER: Electrocution hazard

Always disconnect the power at the supply source before connecting or disconnect-

ing wires to the terminal block. The cover must be installed over the terminal block

before applying power.

If redundant power supplies are used, ensure that both power supply sources are

disconnected.

CAUTION:

This equipment is intended only for use in a restricted access area.

Access to the battery located inside the unit is prohibited.

Access to wiring terminals and replaceable modules is restricted to skilled persons

only.

For improved convectional cooling and airflow, make sure that there is at least one rack

unit (44 mm) of space exists between devices on the rack.

Forced airflow is not required. However, any increase in airflow will result in a reduction

of ambient temperature and improve the long-term reliability of the equipment mounted

in the rack space.

When installing the device in a closed or multi-device rack, be aware that the ambient

temperature of the rack may be higher than the ambient temperature of the room. Make

sure the rack is installed in a suitable environment that can withstand the maximum am-

bient temperature generated by the rack.

Do not exceed the maximum number of devices or weight restriction specified by the rack

manufacturer.

Do not overload the supply circuit. Refer to the overcurrent protection and power supply

ratings specified by the rack manufacturer.

Make sure the rack and all devices have a proper ground-to-Earth connection. Pay partic-

ular attention to power supply connections other than direct connections to the branch

circuit (e.g. power strips). Ensure that the rack mount adapters are installed on the cor-

rect side of the chassis.

Do not store the switch in locations where it will be subject excessive dirt and dust and

high humidity. Conformal coating is recommended for humid/moist applications.
