Ensure that the chassis ventilation openings in the unit are NOT BLOCKED.



DO NOT plug in, turn on or attempt to operate an obviously damaged unit.

Vorsichtsmaßnahmen



Unplug the power supply cord from the wall socket BEFORE attempting to remove and/or replace the power supply.



The system has a redundant power supply option. Disconnecting one power supply cord disconnects one power supply module only. To isolate the unit completely from the mains, disconnect all power supply cords.

Lesen Sie die folgenden Vorsichtsmaßnahmen sorgfältig, um das Risiko von Stromschlag oder Brandgefahr zu vermindern.



Jede Wartung sollte NUR von befugtem Wartungspersonal durchgeführt werden. Das Aggregat enthält keine vom Anwender zu wartenden Teile.

To insert the power supply, switching modules, and interface cards, configure optical ports for the interface modules and connect network cabling and power to the unit see Chapter 4.

You can mount the CoreBuilder 7000 family ATM switch in a 19-inch distribution rack. This section describes how to prepare the unit and the distribution rack, and mount the unit in the distribution rack. Please read all of the instructions carefully before beginning the installation.

For the basic mechanical and space requirements for the distribution rack “Distribution Rack Requirements” on page C-3.

Preparation

To prepare the CoreBuilder 7000 family ATM switch and distribution rack for installation:

Attach the mounting brackets onto the sides of the CoreBuilder 7000

family ATM switch using the mounting bracket screws (M4 x 8 Phillips). Determine whether or not the distribution rack has threaded holes. If the

holes are threaded, “Mounting the CoreBuilder 7000 Family ATM Switch” on page 3-6.

If the holes are not threaded, you must insert “G” clips. To determine

where to insert “G” clips, locate the top of a universal mounting hole pattern on the left mounting rail. In the universal rail pattern, the spacing between holes is 1/2 inch, 5/8 inch, 5/8 inch, and 1/2 inch. To find the top of the pattern, locate the midpoint between any two holes that are spaced half an inch apart. Figure 3-1 shows the universal mounting hole pattern.

the holes designated for the unit model.

Repeat steps 3 and 4 for the right rail. Ensure that you start on the same

hole space.

You are now ready to mount the CoreBuilder 7000 family ATM switch into the distribution rack.

Safety Precautions

When handling replacement parts, 3Com recommends that you always use a wrist strap connected to a proper ground. This helps prevent the module from being damaged by electrostatic discharge. Additionally, when not in use, the module should be stored in an antistatic bag.

If the system is powered on when you are replacing a module, do not insert any metal objects, such as a screwdriver or a finger with jewelry, in the open slot. This could cause burns or other bodily harm, as well as system damage.

Vorsichtsmaßnahmen

Mesures de sécurité

Wenn Sie Ersatzteile handhaben, benutzen Sie immer ein Band am Handgelenk, daß gut geerdet ist. Das hilft vermeiden, daß das Ersatzteil durch elektrostatische Entladung beschädigt wird. Darüber hinaus sollte ein Modul, wenn nicht benutzt, in einem antistatischen Beutel aufbewahrt werden.

Steht das System unter Strom, wenn sie ein Modul installieren oder auswechseln, führen Sie keine Metallgegenstände, wie einen Schraubenzieher oder einen Finger mit Schmuck in den offenen Schlitz ein. Das könnte zu Verbrennungen oder anderen Körperschäden führen, sowie auch zu Schäden am System.

Lors de la manipulation des pièces de rechange, 3 Com recommande de toujours utiliser une bande attachée au poignet et reliée à la terre. Cela aidera à éviter que la pièce ne soit endommagée par une décharge électrostatique. De plus, lorsqu'il n'est pas utilisé, le module doit être conservé dans un emballage antistatique.

Si le système est alimenté lors de l'installation ou du remplacement d'un module, ne jamais insérer d'objet métallique tel qu'un tourne-vis ou un doigt portant un bijou dans la fente. Cela est susceptible de provoquer brûlures ou autres dommages corporels, et d'endommager le système.
