Installing Power Supply Units And Connecting Power - Extreme Networks Summit X150 Series Hardware Installation Manual

Appendix A: Safety Information
WARNING!
The Ethernet ports of the equipment and its sub-assemblies are suitable only for intra-building connections
(within the same building) or for connections to unexposed wiring or cabling. (See the conditions listed above.) The
Ethernet ports of this equipment or its sub-assemblies must not be metallically connected to interfaces that connect
to the outside plant (OSP) or its wiring. Ethernet interfaces are designed for use only as intra-building interfaces
(described as Type 2 or Type 4 ports in GR-1089-CORE, Issue 6) and require isolation from the exposed OSP
wiring. The addition of Primary Protectors is not sufficient protection to connect these interfaces metallically to
OSP wiring.
This warning does not apply to T1/E1 ports because T1/E1 ports have built-in isolation and surge protection that
allows them to be connected to OSP wiring.

Installing Power Supply Units and Connecting Power

For the ratings and power input requirements of each power supply unit, see Appendix B of this guide
or the data sheet for the power supply at http://www.extremenetworks.com.
WARNING!
Be sure to satisfy the requirements listed in this section when you install Extreme Networks power supplies
or connect power.
When you install any power supply:
Do not use excessive force when you insert a power supply into the bay.
●
Do not attempt to open the power supply enclosure for any reason; the power supply does not
●
contain user-serviceable parts. In the event of failure, return the defective power supply to Extreme
Networks for repair or replacement.
Do not put your hand into an open power supply bay when a power supply is not present.
●
Before you work on equipment that is connected to power lines, remove all jewelry, including
●
watches. Metal objects heat up when they are connected to power and ground and can cause serious
burns or weld the metal object to the terminals.
An electrical arc can occur when you connect or disconnect the power with power applied. This
●
could cause an explosion in hazardous area installations. Be sure that power is removed from the
device.
When you install or replace equipment, always make the ground connection first and disconnect the
●
ground connection last.
When you install AC power supplies:
For switches with field-replaceable power supplies, do not connect the power supply to an electrical
●
source when the power supply is not installed in the switch; doing so would expose a hazardous
energy and poses a potential shock and fire hazard.
Plug power supplies only into properly grounded electrical outlets to help prevent electrical shock
●
and to comply with international safety standards.
