This section describes requirements for the site in which the Cisco 6100 with NI-2 system will be installed. Before you install the Cisco 6100 with NI-2 system, ensure that all the criteria in this section are met. The section describes the following:
Proper operation of the Cisco 6100 with NI-2 system depends on a proper environment. This section describes environmental requirements for the site in which you will install the Cisco 6100 with NI-2 system. The section describes the following requirements:
The system can tolerate a wide range of temperatures. Table 2-1 provides the Cisco recommendations for temperature, altitude, and humidity conditions in a CO environment.
Table 2-1 CO Operating Environment Requirements
| Environmental Specifications | Description |
|---|---|
41 to 104ºF (5 to 40ºC)—Operating |
|
Warning To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 104°F (40°C). |
The following hardware locations ensure proper ventilation for the Cisco 6100 with NI-2 system:
You can install a combination of the Cisco 6100 with NI-2 system components in a 7-foot rack:
|
Warning Systems using a Cisco 6100 chassis must connect to the network through a POTS splitter. |
The Cisco 6100 with NI-2 system fits in a 23-inch wide rack. See Table 2-2 for individual rack space requirements.
Table 2-2 Rack Space Requirements
| Component | Rack Space | Height | Depth |
|---|---|---|---|
| 1An RU is equal to 1.75 inches (4.45 cm).
2Leave 1 RU of space under the fan tray. This space allows for the intake plenum and for cabling back to front for the NI-2 card. |
Depending on your configuration type, plan accordingly so that the central office (CO) rack accommodates your needs. Use Table 2-3 to calculate the rack space necessary for your Cisco 6100 with NI-2 system configuration. The total amount of rack space should not exceed 42 RUs. If your total configuration exceeds 42 RUs, either replan your configuration or use more than one rack to house the Cisco 6100 with NI-2 system components.
Table 2-3 Rack Space Calculation for the Cisco 6100 with NI-2 System Configurations
| 1If you are using multiple Cisco 6100 chassis in your configuration, a fan tray is required to be installed under each chassis.
2Either a Cisco 6120 or a third-party POTS splitter can be used in a Direct Connect with a POTS splitter configuration. |
The central office (CO) power source or rectifier supplies external power to the system as -48 VDC from the fuse and alarm panel. Power connections from the fuse and alarm panel are wired separately to the Cisco 6100 chassis and the fan tray. Connections for single- and dual-power feeds are provided. The power input connections are redundant, and only one is absolutely necessary for system operation. The nominal voltage is -48 VDC; the minimum operating value is -36 VDC; and the maximum operating value is -60 VDC.
Before you connect the system to a power source, verify that the power source is properly grounded and it falls within the internal power supply rating.
Depending on your configuration type, calculate the typical power required for each Cisco 6100 system component. After you calculate the typical power, determine the minimum fuse value for each component that is wired to the fuse and alarm panel. Use Table 2-4 to calculate the minimum fuse rating that is necessary for each of your Cisco 6100 with NI-2 system components.
|
Note The power rating label that is supplied on the rear of each chassis and fan tray indicates the maximum fuse value for the chassis or the fan tray. |
Table 2-4 Fuse Calculation for the Cisco 6100 with NI-2 System Components
| 1For a Direct Connect configuration, the maximum number of Cisco 6100 chassis is two per rack.
