Poe Devices; Selecting Power Supply Cords - Extreme Networks Summit X450a-24tDC Hardware Installation Manual

Safety Information
Cable runs between buildings are directly buried.
●
Cable runs between buildings are in an underground conduit, where a continuous metallic cable
●
shield or a continuous metallic conduit containing the cable is bonded to each building grounding
electrode system.
CAUTION
Failure follow these requirements for cable routing conditions may expose the user to electrical shock and expose
the unit to errors or damage.
WARNING!
The intra-building ports of the equipment or subassembly is suitable for connection to intrabuilding or unexposed
wiring or cabling only. The intra-building port(s) of the equipment or subassembly MUST NOT be metallically
connected to interfaces that connect to the outside plant (OSP) or its wiring. These interfaces are designed for use
as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require
isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to
connect these interfaces metallically to OSP wiring.

PoE Devices

When connecting power over Ethernet (PoE) devices to a PoE switch, all connections between the PoE
device and the switch must remain inside the same building and use a low-voltage power distribution
system per IEEE 802.3af.

Selecting Power Supply Cords

Extreme Networks provides power input cords shipped in the product box for use in the US and
Canada. Power supply cords for use outside of the United States and Canada are typically provided
separately by third-party distribution centers. Contact the Extreme Networks TAC for questions
regarding the proper selection of a power input cord for your specific switch.
The following are power cord requirements for use on AC-powered Summit family switches and
compatible external power supplies:
Wire: 18 AWG (.823mm
●
no longer then 15ft
Wall plug: Suitable for use in country of installation & approved by local regulatory authority
●
Device connector: IEC320-C13, rated at 10 A, 250 VAC
●
Power cord assembly: Must be rated at 10A, 250V by in-country regulatory authority
●
WARNING!
When using multiple power supplies, make sure that each power supply is attached to independent circuits breakers.
See the installation instructions for the power supply for proper sizing of circuit breaker.
Make sure that the source outlet is properly grounded according to the country's local electrical requirements before
plugging the AC supply power cord into a power supply.
