1. Safety Procedures – General Precautions
General - Please read the following precautions carefully before installing and connecting the
system to a power source.
Note – Only qualified and trained service personnel (in accordance with IEC 60950 and AS/NZS
3260) should install, replace, or service the equipment. Install the system in accordance with
Country, National or to the U.S. National Electric Code if you are in the United States.
Precautions:
1. The building facilities in which the product will be used requires a fuse or circuit breaker
no larger than 15 A for 120 Vac (U.S.A.) or 10 A, 230 Vac (international). The building
facilities must protect the Midspan from over current or short-circuits.
2. Before connecting the Midspan to a power source (including power cord requirements),
read the Midspan Hardware Setup procedure in Section 2. This procedure as with all
procedures and instruction s can be found in the Midspan User Manual. To download a
copy of the Manual, visit “www. Phihong.com”.
3. To prevent the Midspan from overheating, do not operate the product in an area that
exceeds the maximum recommended ambient temperature of 40 ºC. Allow at least 3 to 4
inches of clearance around all ventilation openings.
4. In order to support the Midspan weight, do not stack the chassis on any other equipment.
Shelf mounted equipment requires a stable and durable surface. When installed, do not
push or pull on the Midspan when the equipment is installed.
5. The Midspan consists of two rows of “Data and “Data & Power” ports. The ports use
RJ-45 data sockets. Do not connect telephone cables into these ports. Only RJ-45 data
cables may be connected to these sockets.
6. Do not work on the Midspan system or connect or disconnect cables, during periods of
lightning activity.
7. The AC or DC plug/socket combination must be accessible at all times, as it serves as the
main disconnect device to the product.
8. Before servicing the product, always disconnect the product from its AC and DC source.
9. Disposal of this product should abide by all appropriate National laws and regulations.

1. Sicherheitsmaßnahmen – Allgemeine Vorsichtsmaßnahmen
Allgemein – Lesen Sie die folgenden Vorsichtsmaßnahmen sorgfältig durch, bevor Sie das
System installieren und an eine Energiequelle anschließen.
Hinweis – Das Gerät darf nur durch qualifiziertes und geschultes technisches Personal (gemäß
IEC 60950 [Vorschrift 60950 der Internationalen Elektrischen Kommission] und AS/NZS 3260
[Vorschrift für Australien und Neuseeland]) installiert, ersetzt oder repariert werden. Installieren
Sie das System auch in Übereinstimmung mit den geltenden nationalen oder europäischen
Vorschriften bzw. der NEC-Vorschrift, falls Sie sich in den Vereinigten Staaten befinden.
Vorsichtsmaßnahmen:
1. Die Gebäudeinstallationen, in denen das Produkt benutzt wird, müssen über eine
Sicherung oder einen Schutzschalter mit maximal 15 A für 120 VAC (USA) oder 10 A
für 230 VAC (international) verfügen. Die Gebäudeinstallationen müssen das Midspan-
Device vor zu starkem Strom oder Kurzschlüssen schützen.
2. Lesen Sie vor dem Anschließen des Midspan-Device an eine Energiequelle
(einschließlich der erforderlichen Anschlussleitungen) die Setup-Anleitung für Ihre
Midspan-Hardware in Kapitel 2 genau durch. Dieses Verfahren wird zusammen mit allen
weiteren Vorgängen und Anweisungen im Benutzerhandbuch für das Midspan-Device
beschrieben. Sie können das Benutzerhandbuch unter "www. Phihong.com"
herunterladen.
3. Um das Midspan-Device vor Überhitzung zu schützen, benutzen Sie das Produkt nicht in
Räumen, die die maximale empfohlene Umgebungstemperatur von 40oC überschreiten.
Lassen Sie um alle Lüftungsöffnungen herum mindestens 7,5 bis 10 cm (3-4 inches) frei.
4. Stützen Sie das Gewicht des PoE Midspan-Device nicht ab, indem Sie das Gehäuse auf
ein anderes Gerät stellen. Falls Sie das Gerät auf ein Gestell montieren, muss dieses eine
stabile und haltbare Oberfläche haben. Nach der Installation des Systems bewegen Sie
das Midspan-Device nicht mehr.
5. Das Midspan-Device enthält zwei Reihen mit "Datenports" und "Daten- und Stromports".
Die Ports verwenden RJ45-Datenanschlüsse. Schließen Sie keine Telefonkabel an diese
Ports an. Es dürfen nur RJ45-Datenkabel an diese Eingänge angeschlossen werden.
6. Führen Sie an dem Midspan-System keine Arbeiten durch, schließen Sie keine Kabel an
und trennen Sie keine Kabelverbindungen während Gewittern mit Blitzen.

7. Der Steckanschluss für Gleich- oder Wechselstrom muss jederzeit zugänglich sein, da er
als Haupttrenngerät für das Produkt dient.
8. Trennen Sie das Produkt immer erst von der Stromquelle, bevor Sie Wartungs- oder
Reparaturarbeiten daran durchführen.
9. Entsorgen Sie dieses Produkt gemäß aller geltenden Gesetze und Vorschriften Ihres
Landes und der EU (falls Sie sich in einem Land der EU befinden).

U.S.A. and
Canada
•The cord must have a minimum of 10A rated current
competence.
•The cord must be CSA or UL approved.
•The minimum requirement for the flexible cord is:
o18 AWG (10A)
oThree-conductor (Line, Neutral, Ground)
oType SV (Stranded Vacuum Rubber Jacketed) or

France and Peru
•IT equipments cannot power this device. In the case of an IT
powered device, the unit needs to be powered by 230 V through
an isolation transformer with a ratio of 1:1 and the secondary
connection (Neutral) is properly grounded.
The Midspan must have access to a nearby power outlet. By disconnecting the power
cord from the outlet, you will eliminate power from the device.
The flexible cord that connects to the Midspan must have a configuration to connect with
an EN60320/IEC320 inlet connector.
According to the EN60950/IEC 950 specifications, this device functions under SELV
(Safety Extra Low Voltage) conditions. The conditions are true if the equipment and the

2.3 Connecting Power Cables
AC power cord:
The AC power cable is connected to the AC power connector located in the rear side of
the Midspan and the power outlet.
2.4 Connecting Ethernet Cables
Ethernet Cable
The Ethernet cable is connected to the RJ45 connector located in the front side of the
Midspan.
*Ethernet cables are not included
** AC Power Cord may be order separately
2.5 Powering Up
Midspan is powered by the power cord. In order to apply or remove power to/from the Midspan,
connect or disconnect the AC power cable to/from the AC power connector on the rear side of
the unit.
With AC power applied, the unit starts-up and the internal fans are active. The device runs
through a quick power-on test, which takes less than 5 seconds. During this period, all ports are
initially disabled and the port indicators light up. The sequence of the port LEDs are shown in
section 2.6 LED Indicator – Cold Start. Ports are now operating under normal conditions.
