1. Safety Procedures
1.1. 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 15A for 120Vac (U.S.A.) or 10A, 230Vac (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
instructions 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°C. 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
connect to these sockets.
6. Do not work on the Midspan system or connect or disconnect the cables, during periods of lightning
activity.
7. The AC or DC plus/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 products from its AC and DC source.
9. Disposal of this product should abide by all appropriate National laws and regulations.

1.1 Sicherheitsmaßnahmen – Allgemeine Vorsichtsmaßnahmen
Allgemein – Lesen Sie die folgenden Vorsichtsmaßnahmen sorgäfltig durch, bevor Sie das System
installieren und an eine Energiequelle anschließen.
Hinweis – Das Gerät derf nur durch qualifiziertes und ausgebildeten Dienstpersonal (gemäß IEC
60950 [Vorschrift 60950 der Internationalen Elektrischen Kimmission] 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 15A für 120 Vac (USA) oder 10A für 230Vac (international)
verfügen. Dis Gebäudeinstallationen müssen das Midspan-Device vor zu starkem Strom oder
Kurzchlüssen 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 schübenutzen Sie das Produkt nicht in Räumen,
die maximale empfohlene Umgebungstemperatur von 40°C 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 Kabel an und trennen Sie keine
Kabelverbindungen während Gewittern mit Blitzen.
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 Wartung 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).

2.5 Powering UP
Midspan receives power via 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 10 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.
2.6 LED Indicator:
Cold Start:
a. AC – LED turns ‘green’ » remains on
b. NIC – LED turns ‘green’ » red » green » turns off » red » turns off (unless connected)
c. 24-Ports (with ports connected) – LED turns ‘orange’ » green » orange » green » turns off – LED
turns ‘green individually » ports 1,9,17 » ports 2,10,18 » ports 3,11,19 » ports 4,12,20 » ports
5,13,21 » ports 6,14,22 » ports 7,15,23 » ports 8,16,24 » All 24-Ports are connected – LED remains
‘green’
d. 24-Ports (without ports connected) – LED turns ‘orange’ » green » orange » green » turns off – LED
blinks ‘orange individually » ports 1,9,17 » ports 2,10,18 » ports 3,11,19 » ports 4,12,20 » ports
5,13,21 » ports 6,14,22 » ports 7,15,23 » ports 8,16,24 » Blinks ‘orange’ across all 24-Ports
When ‘System Reset’ is clicked on the GUI (applications file):
a. AC – LED remains ‘green’
b. NIC – LED remains off until the unit is connected
c. 24-Ports (with ports connected) – same sequence as Cold Start
d. 24-Ports (without ports connected) – same sequence as Cold Start

USB Device (Midspan)
Internal Function
Connects USB Port (PC) to
device (Midspan) via USB Cable
Internal USB device (Midspan)
sends a signal to your PC,
creating a “Virtual COM
Port.” A Virtual COM Port
corresponds to a serial
communication port.
Wait for the PC to respond
USB Port (PC)
The PC automatically detects
the newly installed hardware.
This function is called Plug
& Play, available with a USB
connection
The PC quickly identifies the
connection as Serial Com.
Windows will automatically
install your device on an
available serial COM port.
Changes may be made via
Device Manager. Section 3.2
discusses Device Manager.

4.2 GUI System Control and Information:
The System Control and Information panel on the GUI supports the main system level parameters for
the μP. It also displays information about the PoE ID, firmware revision and system status.
Figure 20: System Setup, Control, Information, and Port Commands
The system level parameters that can be configured are:
• System Reset – This is a function that allows the GUI to reset the software on the μP. (If System
Reset is set and the GUI does not respond, user must click “Reset GUI”)
• Firmware Download – This feature is used to download new application/firmware codes onto
the μP. Please refer to the Phihong website www.midspans.com for the latest firmware for your
midspan – POE Firmware.
Note: Please allow the GUI a few seconds to respond to the commands selected. DO NOT click or
check any commands simultaneously. If a command is selected more than once within two
seconds, the GUI may not respond properly.
The “Save Parameters to Flash” button will save system and port parameters to flash memory, so that
they can be used to the firmware across reboots of the μP.
