Preventing Electrostatic Discharge Damage
Proper ESD protection is required whenever you handle Cisco DSLAM equipment. Installation and maintenance personnel should be properly grounded using ground straps to eliminate the risk of ESD damage to the equipment. Cards are subject to ESD damage whenever they are removed from the chassis.
The line cards support hot swapping. Hot swapping allows you to remove and replace the line cards without disconnecting the system power. When the system detects that you have added or removed a line card, it automatically runs diagnostic and discovery routines, and acknowledges the presence or absence of the line card.
Installation and Replacement Suggestions
The following examples list recommended installation and replacement practices for the Cisco 6100 with NI-2 system cards.
Caution Any card that is only partially connected to the backplane can disrupt system operation.
Do not force the card into or onto the chassis backplane connectors. This action can damage the pins on the connectors if they are not aligned properly with the card.
Do not force the line card into its slot. This action can damage the pins on the backplane if they are not aligned properly with the line card.
Ensure that the system I/O card is straight and parallel to the chassis backplane when you install the card onto the connectors. The pins on the connectors can be damaged if the card is not installed correctly.
Ensure that the card is straight and not at an angle when you install the card in the slot. Installing the card at an angle can damage the card. Use the guide rails to install the card correctly.
Fully depress the ejector tabs to ensure that the card connector mates with the backplane correctly. Firmly seat the card in the slot.
Site Requirements
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.

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).
Ventilation
The following hardware locations ensure proper ventilation for the Cisco 6100 with NI-2 system:
Chassis placement—Leave 1 rack unit (RU) of space under the fan tray. The space is for the intake plenum and for the pass-through cables to the NI-2 card.
Fan tray installation—You must bolt the fan tray into the rack and connect the fan tray to a Cisco 6100 chassis.
POTS splitter location—The POTS splitters do not dissipate heat and should be positioned at the bottom of the rack.
Space
You can install a combination of the Cisco 6100 with NI-2 system components in a 7-foot rack:
Cisco 6100 chassis—Maximum of two chassis are allowed per rack
POTS splitter (either a Cisco 6120 or a third-party POTS splitter)
Fan tray—Required under each Cisco 6100 chassis when using multiple Cisco 6100 chassis
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.
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.

Power
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.
