2.4 Pre-Installation Site Requirements
Before installing E5-APP-B cards into an EAGLE shelf, make sure that the requirements described in both of the following sections have been met.
2.4.1 Generic Site Requirements
Ensure that the site where the product will be installed conforms to the specifications listed in the following sections. These specifications are standard telephony industry requirements for equipment installation.
Fire Protection
Local fire protection codes must be satisfied in the equipment room where the system is to be located.
Environmental Requirements
Oracle Communications products are designed for environments that have temperature and humidity controls. Temperature and humidity controls must be activated as quickly as possible for equipment to operate at an optimum level.
When temperature and humidity controls fail, the equipment has been tested to operate within the following ranges:
-
-
5˚ C to 40˚ C (41˚ F to 104˚ F) for normal operation
-
-5˚ C to 50˚ C (23˚ F to 122˚ F) for no more than 96 hours in duration and at elevations less than 1800 meters
-
-5˚ C to 50˚ C (23˚ F to 122˚ F) for storing the product
-
-
-
5% to 85% non-condensing for normal operation
-
5% to 90% non-condensing (but not to exceed 0.024 kilograms of water per kilogram of dry air) for no more than 96 hours in duration and at elevations less than 1800 meters
-
Oracle Communications products are tested to operate at an elevations within the following range:
-
Minimum: 60 meters below sea level at ambient temperature of 30˚ C (86˚ F)
-
Maximum: 4000 meters above sea level at ambient temperature of 40˚ C (104˚ F)
HVAC Requirements
Oracle Communications products are designed to bring cool air in from the bottom front and exit heated air out the top rear of the installed equipment.
The required HVAC (Heating, Ventilation, and Air Conditioning) capacity depends on the installed equipment. To calculate needed HVAC capacity, determine the total wattage of the installed equipment and use the following formula:
BTUs/hr. = watts x 3.413
The amount of power required by frame components is found at: DC_PowerReqmts.pdf.
The E5-APP-B card must be installed in a fully populated EAGLE shelf with a fan tray and air management cards, if necessary.
Lighting
Adequate lighting should be provided in the room where the equipment is to be located. Lighting fixtures must be far enough from the equipment and cables to prevent heat damage and to allow safe access to equipment and cables.
Earthquake Resistance
All Oracle Communications system configurations are designed to assure that the system remains operational during and after an earthquake, even when the system is located on the upper floors of a zone 4 central office.
Space Requirements
Provide space as described in Generic Site Requirements. These space requirements provide for Oracle Communications equipment installed in a 23-inch heavy-duty frame, which measures 7 feet high. Separator panels and end panels add to the width of multiple frame systems.
Table 2-1 Space Requirements
| Building Area | Dimensions | Notes |
|---|---|---|
|
Halls |
4.5 feet wide by 8 feet tall (1.4 meters wide by 2.4 meters tall) |
To provide a clear, uncluttered route for moving equipment between the loading/receiving dock and the planned system location |
|
Frame location |
30 inches wide by 24 inches deep (76.2 cm wide by 60.96 cm deep) |
Floor area recommended for one Oracle Communications frame (multiply by the number of frames listed on the Initial Sales Order) Total area per frame = 720 square inches (5.0 square feet) (0.465 square meters) |
|
Side aisles |
4 feet (1.2 meters) |
To allow maneuvering frames into place and provide ample work space around the equipment |
|
Front and rear access |
3 feet 6 inches (107 cm) |

In addition, when planning the installation, be sure to take into account spare hardware storage, modems, terminals, printers, cross connect panels, and all other items that might require space in a system.
Floor Loading
Oracle Communications products installed in heavy-duty control or extension frames are designed for installation on raised or solid floors, which are recommended to have a distributed load capacity of no less than 100 pounds per square foot (504 kg/m2) and a maximum weight of EAGLE 5 ISS 850 lbs (386 kg).
Use the following equation to calculate the floor loading:
Distributed floor capacity = Total equipment weight/floor area
2.4.2 Grounding and Power Requirements
Before installing E5-APP-B cards into an EAGLE shelf, make sure that the grounding and power requirements in the appropriate following sections have been met.
Grounding Requirements
Oracle Communications systems operate as digital isolated ground plane systems in a central office environment and require a single connection to the central office ground window. The system’s ground cables must provide the sole grounding connection between the entire system and the central office grounding.
warning:
Always install an isolator pad between the frame and ground. Oracle Communications frames are shipped with isolator pads to completely isolate the frames from ground. If a non-Oracle Communications frame is used, an isolator pad must be provided.The system can use three types of grounding paths:
-
Battery return
The battery return grounding path is the return path for all –48VDC loads in the system. This path is isolated from other system grounds and connects to the rest of the central office through the –48VDC return connections located on the breaker panels of each frame.
-
Logic Ground
Some system types require connection to a logic ground. The logic ground path provides a common voltage reference point between all circuit boards of a system. Each connection terminates to the system ground. The logic ground path is shown on your system’s interconnect drawing. The logic ground path does not carry current.
-
Frame/shelf ground
The frame/chassis ground path provides a low impedance connection for all metal parts of the entire system, including the frame, doors, shelves, and end panels. Each frame/chassis connection within the system lineup terminates to the frame and connects to the main ground by way of Htaps, #6 American Wire Gauge (AWG) to 1/0 cable.
Note:
The frame/chassis ground path does not carry current.For products installed in a frame, the doors installed are grounded to the frame through a two-hole lug ground wire and through a screw-down latch. Figure 2-4 shows a cutaway view example of an open frame door showing the door ground strap.

EAGLE Shelf Power Requirements
Note:
EAGLE cannot provision two E5-APP-B cards running the same application in slots with the same power sources in different frames unless the force=yes parameter is used.
