Introduction
Functions and Features
The BL‐69108ENT and BL‐69524ENT, Enterasys Networks’ 8‐port and 24‐port Mid‐Span Power Hubs, support applications in which AC power is difficult to access, such as VoIP phones, wireless LAN access points, or IP network cameras.
The Enterasys Mid‐Span Power Hubs act as “patch panels” and add ~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 Mid‐Span Power Hubs:
•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
•Act as normal patch panels and place ~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)
