rack-environment temperature is within the specified operating
temperature range.

• Mechanical Loading: Do not place any equipment on top of a
rack-mounted unit.

• Circuit Overloading: Be sure that the supply circuit to the rack
assembly is not overloaded.

• Grounding: Rack-mounted equipment should be properly grounded.
Particular attention should be given to supply connections other than
direct connections to the mains.

Montage (Rack Mounting Instructions - German)

SMCRPUPOE -Einheiten können an ein standardmäßiges 19-Zoll Einrichtungsrack, einen
Arbeitstisch oder ein Regal montiert werden. Folgend finden Sie die Montageanweisungen für
jeden Positionstyp.

Rack-Montage

Beachten Sie die folgenden Faktoren, bevor Sie die Rack-Montage beginnen:

• Temperatur: Da die Temperatur innerhalb einer Rackeinheit höher als die
Raumumgebungstemperatur sein kann, stellen Sie bitte sicher, dass die Rackumgebungstemperatur
innerhalb des angegebenen Betriebstemperaturbereichs liegt. (Siehe "Temperature" auf Seite B-1.)

• Mechanische Last: Stellen Sie kein Gerät auf eine Rack-Montageeinheit.

• Stromüberlastung: Stellen Sie sicher, dass der Netzkreis der Rackeinheit nicht überlastet wird.

• Erdung: Die Rack-Montageeinheit muss richtig geerdet werden. Besondere Acht sollten Sie bei
Verbindungen geben, die nicht direkt zum Netz führen.

So montieren Sie Geräte an ein Rack:

1. Befestigen Sie die Metallwinkel mit den im Metallwinkel-Montageset erhältlichen Schrauben an dem

Gerät.

2. Befestigen Sie das Gerät mit vier Rackmontageschrauben (nicht beigelegt) an dem Rack.

3. Wenn Sie nur einen RPU installieren, dann springen Sie bitte über zu "Verbinden mit einer

Stromquelle" auf Seite 2-7 am Ende dieses Kapitels.

4. Wenn Sie mehrere RPU installieren möchten, dann montieren Sie sie untereinander in einer

beliebigen Reihenfolge.

Connecting Switches to the RPU

Caution: DO NOT connect the RPU to an AC power source until

DC power cords have been connected to the supported
switches.

To connect switches to the RPU:

1. Connect one end of an AC cord to the AC socket on each supported
switch, and the other end to a grounded power outlet.

Figure 2-4 Power Socket

2. Connect one end of a DC cord to the redundant power socket on the
supported switch and the other end to an available socket on the RPU.

3. Repeat steps 1 and 2 for connecting up to four supported switches to
the RPU.

4. Connect one end of the AC cord to the AC socket on the RPU, and
the other end to a grounded power outlet.

5. Check the LEDs on the RPU to ensure proper operation. The Link
LEDs for connected switches should light up. If the LEDs indicate
otherwise, see “Troubleshooting” on page A-1 for more information.

• The unit is powered off.

• Indicates a high temperature that is approaching an
over-temperature condition.

• Check that the unit's cooling fans are operating normally.

• Power off the RPU unit and allow to cool.

• If the condition persists, contact Technical Support.

* The fast flashing behavior is approximately three flashes per second. The
slow flashing behavior is approximately one flash per second.

Power and Cooling Problems

If the power indicator does not turn on when the power cord is plugged in,
you may have a problem with the power outlet, power cord, or internal
power supply. However, if the unit powers off after running for a while,
check for loose power connections, power losses or surges at the power
outlet, and verify that the fans on the unit are unobstructed and running
prior to shutdown. If you still cannot isolate the problem, then the internal
power supply may be defective.

Installation

Verify that all system components have been properly installed. If one or
more components appear to be malfunctioning (such as the power cord or
network cabling), test them in an alternate environment where you are sure
that all the other components are functioning properly.
