PoE ++ Connectivity, Arcing, and Temperature Issues
•
PoE is not live until powered device (PD) and powered sourcing equipment (PSE) handshake.
•
When unplugging live PoE, an arc (or spark) occurs between plug and jack contacts.
•
Arcing occurs with ALL mated PoE connections.
•
Ensure jack meets IEC 60512-99-001 for compliance.
•
Ambient jack temperature must be 5 deg. C below maximum jack operating temperature. To operate in
60 deg. C ambient, you need a 65 deg. C rated jack.
See the BICSI webpage for your particular type of PoE (e.g., for
Standard for Installing Commercial Building Telecommunications Cabling. ANSII/NECA/BICSI 568 describes
minimum requirements and procedures for installing the infrastructure for telecoms, including balanced twisted-
pair copper cabling and optical fiber cabling that transport telecommunications signals (e.g., voice, data, and
video). The 2008 NEC standard is a safety code widely adopted in the USA as minimum required safety rules for
the electrical industry. The 2008 NEC points to the ANSII/NECA/BICSI 568 standard as a best practices source
document.
