Notes:

1. The 3721 expansion unit is placed on top of the 3720 base unit, and therefore should be installed after the base unit is installed. The top cover of a 3720 Model 1 or Model 2 is removed when a 3721 expansion unit is installed and the top cover is placed on top of the 3721.

When planning multiple base unit/expansion unit configurations, consider that unit weights and heat outputs are additive.

2. A ventilation system is contained within the 3720 Model 1. The 3721 expansion unit does not contain a ventilation system. When an expansion unit is installed on top of a base unit, the ventilation system of the base unit provides ventilation for the expansion unit.

Direction of airflow is from top to bottom. To maintain airflow, the casters must not be removed from the 3720 Model 1.

IBM 3720 and 3721 Communication Controller Planning and Site Preparation Guide,

GA33-0061.

**No service clearance is required at the two sides of the 3720 Modell, so that units can be positioned side by side, except for the first and last unit in a row. They should be clear of walls and adjacent machines by 850 mm (33-1/2 inches).

***The given kVA values are the maximum possible.

Whatever is the machine configuration or the machine voltage, the primary current will never exceed 12 amperes.

English measurements are shown in parentheses.

Notes:

1. If required, the width can be reduced to 750 mm (29-1/2 inches!' 2. The service clearance can be reduced to 0 when a 3726 is

installed or when another machine is abutted to the left side of the 3725 Model 1, if the covers can be opened as shown on the plan view.

3. A raised floor is not mandatory if the 3725 Model 1 has no chan-nel connection. However, the cables should be protected with ramps or trenches.

4. Caster and cable hole locating dimensions are measured from edge of frame, not cover.

5. Ground plates are delivered with the 3725 Model 1. These plates are installed by the service representative during machine installation. Cutaways in the plates correspond to the existing cable hole shown in the plan view.
