This chapter provides a list of tools and equipment and the site requirements needed to install your Cisco 6100 Series system.
Installation preparation of the Cisco 6100 Series system consists of the following:
The Cisco 6100 Series system has no internal user-serviceable parts. However, you can add or remove a module or a fan without removing power from the system.
The following tools and equipment are required for the Cisco 6100 Series system component installation or removal:
Two people are needed for lifting, installing, and removing a chassis and some of its components (for example, the rear door).
 | Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. |
This section describes requirements for the site in which the Cisco 6100 Series system will be installed. Before you install the Cisco 6100 Series system, ensure that all the criteria in this section are met. The section describes the following:
You can install a combination of the Cisco 6100 Series system components in a 7-foot rack:
| Warning Systems using a Cisco 6100 chassis must connect to the network through a PSC to provide the secondary lightning protection required by NEBS. |
The Cisco 6100 Series system fits in a 23-inch wide rack. See Table 2-1 for individual rack space requirements.
| Component | Rack Space | Height | Depth |
|---|---|---|---|
Fan tray1 | 2 RUs2 | 3.5 in. (8.89 cm) | 12 in. (30.48 cm) |
MC | 9 RUs | 15.75 in. (40.00 cm) | 12 in. (30.48 cm) |
PSC | 4 RUs | 7 in. (17.78 cm) | 12 in. (30.48 cm) |
| 1Leave one RU of space under the fan tray. This space allows for the intake plenum and for cabling back to front for the OC-3c NI module. 2RU = rack unit. |
See "Planning for a Cisco 6100 Series System" for calculation tables necessary to plan total rack space for your Cisco 6100 Series system configuration.
External power is supplied to the system as -48 VDC from the central office (CO) power source or rectifier to the fuse and alarm panel. Power connections from the fuse and alarm panel are wired separately to the MC and the fan tray. Connections for single and dual -48 VDC 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 unit to a power source, verify that the power source is properly grounded and it falls within the internal power supply rating. The internal power supply rating for the MC is 364W maximum.
You will need to calculate the watts and amperage needed with each Cisco 6100 Series component. See "Planning for a Cisco 6100 Series System" for calculation tables necessary to determine the fuse amperage for each component that is wired to the fuse and alarm panel. Also, the calculation tables in this appendix can help you determine if the watts in your rack exceed the acceptable levels. If the watts exceed the acceptable levels, you either replan your configuration, or use more than one rack to house the Cisco 6100 Series system components.
| Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back. |
| Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety: |
We strongly recommend that you mount the Cisco 6100 Series system in a rack. Ensure that vertical hole spacing on the rack rails meets standard EIA-310-C requirements---1 inch (2.54 cm) spacing. All portions of the rack are equal to or less than the NEBS maximum allowances of 12 inches.
When you install the Cisco 6100 Series system chassis in a rack, be sure to allow enough room to access the backplane of the unit for wiring and cabling purposes. The majority of the connectors are located on the backplane.
The following ensure proper ventilation for the Cisco 6100 Series system.
Proper operation of the Cisco 6100 Series system depends on a proper environment. The system can tolerate a wide range of temperatures. Table 2-2 provides the Cisco recommendations for temperature, altitude, and humidity conditions in a CO environment.
| Environmental Specifications | Description |
|---|---|
41 to 104ºF (5 to 40ºC)---Operating |
| Warning To prevent the Cisco 6100 Series system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 104°F (40°C). |
