PD-6548 1 Safety Information 1.1 General Guidelines Read the following safety information before carrying out any installation, removal or any maintenance procedure on the Power over Ethernet Midspan. Warnings contain instructions that must be followed for personal and product safety. Follow all instructions carefully. WARNINGS a • Read the Installation Instructions in Section 3 before connecting the Power over Ethernet Midspan to its power source.
PD-6548 1.2 Power Cord In the event that the power cord is replaced, the replacement must meet local requirements. • For reliable connection to an AC MAINS SUPPLY, equipment provides an appliance IEC60320 inlet for connection of a detachable power supply cord. • The power socket outlet must be located near the Midspan and be easily accessible.
PD-6548 2 About the Power over Ethernet Midspan PowerDsine’s Midspans family, injects DC power over data-carrying Ethernet cabling. The PD-6548 Midspan, supports 48 ports in a 10/100BaseTx Ethernet network, over TIA/EIA-568 Category 5/5e/6 cabling. DC operating power, for data terminal units, is fed over the unused pairs of the cabling (7/8 and 4/5). The Midspan powers devices that are Power over Ethernet enabled, or are equipped to receive power over Ethernet.
PD-6548 2.2 2.2.1 10/100BASE-TX Ports Definition Data Input Ports The Midspan has 48 10/100Base-TX data input ports, configured in a noncrossover manner (straight-wired). These ports located on the PoE’s rear panel of front box, are designed to carry Ethernet data only (Tx/Rx) over the standard 2-wire pairs (pins 1/2 and 3/6) and are typically connected to existing Etherner switch. 2.2.2 Data & Power Output Ports The Midspan has 48 Data & Power output ports, located on the front panel (Figure 2-1).
PD-6548 2.3 Indicators A set of indicators provide the status of the Power over Ethernet Midspan and its ports. Refer to Table 2-1 and Table 2-2 for status information during operation. 2.3.1 Primary Power Indicators A Primary Power LED (labled “AC”) is located on the front panel; the LED provides Power over Ethernet Midspan power status. When the indicator illuminates in green, it means that the Midspan receives AC power. The “AC” indicator lits in orange to indicate Built In test failure.
PD-6548 Table 2-1: Power Status Indications Indicator Color Off AC Symptom Internal power supply unit is unplugged or faulty Remarks Internal power supply voltage is too low. Green Indicates AC power Internal power supply voltage input active is within tolerance. Orange Internal problem alarm Built in Test (BIT) failed. Table 2-2: Port Status Indications Port LED Color Off Green Green blinks at a 1 sec. rate Green blinks at a 0.5 sec.
PD-6548 2.4 Connectors The Midspan’s front panel includes a Console port (RJ-45 connector) that supports two communication types: 1. Standard DTE Ethernet connector only at the web managable version of the midspan. This connector is a standard 10/100BaseTX port that is used for remote management of the device (see Table 2-3). For connecting the port to a switch output, use a straight-through ethernet cable. for connecting the port directly to a PC port, use a crossed-over ethernet cable.

PD-6548 3 Installing the Power over Ethernet Midspan 3.1 Background The Midspan is connected (see Figure 3-1) in series to an Ethernet switch/hub. The data outputs from the switch are connected to Midspan’s input ports. The Midspan delivers power over spare twisted pairs (pins 7/8 and pins 4/5) of the Category 5 cabling, without degrading the quality of data communications of the output ports. The installation require the Midspan to be rack mounted, as described in the next Paragraph.
PD-6548 3.2 Rack Mounting Brackets The Midspan is supplied with mounting brackets, plates and screws utilized for assembling the Midspan in an 19-in rack. 1. Install two clip nuts on each bracket. 2. Tighten two brackets to both sides of the rack‘s rails using the supplied plates and 10-32” screws as shown below. DETAIL-A 2 PLS. RAIL CLIP NUT BRACKET PLATE SCREW CSK NF 10-32 (x2) CLIP NUT Power over Ethernet Solutions 18 Cat. No.
PD-6548 3.3 Routing the Input Ports Cables The ports on the front panel of the Midspan are configured as "Pass Through" ports for all 48 conductors of the RJ-45 connectors. Use Category 5 jumpers cables with a diameter that is less than 0.25 inch in making connections. *Using an appropriate bench, connect all the cables to the Midspan as follows: 1. Connect cables to the Data input ports as shown below: Chasis ‘Ears’ 2. Start connecting the cables in groups of six as shown above.
PD-6548 Figure 3-2: Cable Connections 4. Upon completion of 48 cables connections, the Midspan should be installed into the rack. Power over Ethernet Solutions 20 Cat. No.
PD-6548 3.4 Assembling Midspan to Rack Assemble the Midspan (including its cables) to the previously installed brackets as shown below, using two 10-32” screws plus lock washer and flat washer (one on each side of the rack). Note: Verify that the Midspan’s ventilation holes on both sides are not blocked and are free of dust and foreign objects! Power over Ethernet Solutions 21 Cat. No.
PD-6548 3.5 Connecting Data Cables 1. Connect the previously routed cables to the switch’s output ports. 2. Connect the cables from the IEEE 802.3af ready terminals (PDs) to the corresponding Data & Power ports on the Midspan’s front panel. 3.6 Connecting Power Cables When using AC source to power the Midspan, plug in the provided power cord at the rear AC connector. Notes: ♦ A readily accessible disconnect device shall be incorporated in the building installation wiring.
PD-6548 3.8 Troubleshooting 3.8.1 Preliminary Steps If you encounter problems, verify that: 1. Power is applied to the Midspan 2. A crossover-type Ethernet cable has not been used 3. The Ethernet cable from the network is connected to the Data input port 4. The Ethernet cable to the PD is connected to the Data & Power output port 3.8.2 Troubleshooting Guide This paragraph provides a symptom and resolution sequence in order to assist in the troubleshooting of minor operating problems.
PD-6548 Table 3-1: Troubleshooting Steps Symptom Corrective Steps AC indicator lit orange Power-on self-test failed: the Midspan detected an internal fault. In this case, contact your local dealer. Midspan repeatedly shutsdown for few minutes and then starts Verify that the ventilation holes are not blocked. The end device operates, but there is no data link. 1. 2. 3. 4. Verify that the port indicator on the front panel is continuously lit.
