1 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.
Port Indicators 1-2 Introduction
2 Installation and Connection Electrical Hazard: Only qualified personnel should install or service this unit.

Technical Considerations Technical Considerations The Enterasys Networks 24-port Mid-Span Power Hub may be placed on a shelf or mounted in a standard 48.26-centimeter (19-inch) rack. Before you mount the unit to a fixed location, consider the following: • Determine optimal placement. • Collect and document network information as required. • Ensure that the length of cable from the Ethernet network source to the powered device does not exceed 100 meters.
Configuration for the 24-Port Mid-Span Power Hub Figure 2-2 2-4 Installation and Connection Typical Configuration for a 24-Port Mid-Span Power Hub
Powering Up Powering Up Simply plug one end of the power cord into the unit, and the other end into a grounded AC power source. Units are typically connected to a power strip or other power outlet that may be cycled on and off. An uninterruptible power supply may also be used. Check to make sure each module installed displays a green Power LED (see Figure 2-3). Verify that any module that does not display a green Power LED is properly seated in the chassis backplane.

3 Troubleshooting Refer to Table 3-1 for a checklist of problems and recommended actions to resolve the problem. If additional support is needed, refer to “Getting Help” on page x. Table 3-1 Troubleshooting Checklist Problem Recommended Action Unit is plugged into the Enterasys Mid-Span Power Hub, but main power LED is “off.” Verify the use of a good AC cable with a good ground connection. Verify that the AC is “hot” and that voltage is between 100 VAC to 264 VAC (50 Hz to 60 Hz).
Troubleshooting Table 3-1 Troubleshooting Checklist (continued) Problem Recommended Action The Mid-Span Power Hub operates and the load device works, but there is no data link. Verify that the Detect/Power Forwarding (blue) LED for the port is “on.” Verify that the Mid-Span Power Hub is connected to the Ethernet network with a good connection. Verify that the Ethernet cable is Category 5, 5e, or 6 and is less than 100 meters in length from the Ethernet source to the load.
