10/100 Base-T Ethernet Interface
When installing an Aspire IP phone (IPhone, Aspire keyset with IP adapter, or H.323 phone), an AC/DC
adapter is required for local power or, for central power, one of the following must be used:
●
24-Port Power PoE-Managed Switch (BF200/24 - NEC standard product)
●
12-Port Power Supply Patch Panel (SN1604 PWRMS - NEC standard product)
●
Power Patch Panel (Cisco)
●
Catalyst PWR Series (Cisco)
When a separate ethernet switch is used, it should be a 100Base/full duplex switch. To avoid network prob-
lems and to ensure good voice quality, do not use a Repeater Hub/10Base.
