Introduction

Functions and Features

The BL-69524ENT, Enterasys Networks’ 24-port Mid-Span Power Hub, supports

applications in which AC power is difficult to access, such as VoIP phones, wireless LAN

access points, or IP network cameras.

The Enterasys 24-port Mid-Span Power Hub acts as a “patch panel” and adds ~48 VDC to

unused (non-data) wires in standard Category 5, 5e, or 6 Ethernet cable. The power unit

delivers both data and power over a single standard Ethernet cable.

Main features of the 24-port Mid-Span Power Hub:

• Fully hot-swappable module banks

• Remote power feeding; powered devices receive power over the Ethernet cable

• Centralized power distribution; one powered device can be connected to a single

in-line unit

• IEEE 802.3af standard powering scheme

• Acts as a normal patch panel and places ~48 VDC on unused Ethernet pins

• Total power available: 15.6 W per port per IEEE specification

• Automatic power-control circuitry to detect a powered device before providing

power

• Fused power surge protection

Port Indicators

Each port has its own LEDs, which display the following:

• Detect/Power Forwarding (blue)

• Power from Chassis (green)
