Unit and Rack

Preparation

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, see “Distribution Rack Requirements” on page 107.

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, see “Mounting the CoreBuilder 7000 Family ATM Switch” on page 28.

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 2 shows the universal mounting hole pattern.

Once the distribution rack is ready, you can mount the CoreBuilder 7000 family ATM switch into the rack.

To mount the CoreBuilder 7000 family ATM switch into the distribution rack:

Carefully lift the CoreBuilder 7000 family ATM switch into place, aligning

the mounting brackets to the holes you have designated for mounting.

A fully-configured CoreBuilder 7000 family ATM switch weighs 43 pounds as shipped. To avoid personal injury, do not lift the unit without assistance.

While holding the CoreBuilder 7000 family ATM switch in place, firmly

insert the mounting screws (10/32 x 1/2 Phillips) into the mounting holes on both sides of the rack.

The unit is now installed in the distribution rack.

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.

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.

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, 3Com 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.

Power Supply Module

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.

The CoreBuilder 7000 family ATM switch provides a dual load-sharing power supply capability where the second unit can serve as a redundant power supply. For more information, see “Redundant Power Supply” on page 85.

For certain combinations of installed interface cards, the second power supply cannot be used as a redundant supply (see “Providing Redundancy for Various Power Loads” on page 90).
