Proper ESD protection is required whenever you handle Cisco equipment. ESD damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Use an antistatic strap during handling.
 |
Tip Use the ESD grounding jack on the fan module for all maintenance except when you are removing the fan module. Use the ESD grounding jack on the DC power entry module (PEM) when you are removing the fan module. |
Follow these guidelines to prevent ESD damage:
|
Caution Periodically check the resistance value of the antistatic strap. Ensure that the measurement is between 1 and 10 megohms. |
This section covers the following topics:
Hot swapping allows you to remove and replace cards without disconnecting the system power. The Cisco 6015 chassis supports hot swapping for the following cards:
If you remove a line card and replace it with the same type of line card, the newly installed line card receives the same provisioning as the original line card. The system resumes operation without any operator intervention.
If an unprovisioned line card is installed for the first time, the system identifies it as present but unprovisioned. Instructions for provisioning the line card are found in the appropriate software guide for your chassis.
 |
Note Reseating the 8xDMT over ISDN during simultaneous DSL and ISDN traffic operation results
in the ISDN signal being temporarily interrupted. To reseat the 8xDMT over ISDN in the chassis, shut down all the subscriber ports on the line card, wait one minute, and then replace the line card. |
Hot swapping allows you to remove and replace a module without disconnecting the system power. The Cisco 6015 chassis supports hot swapping for the fan module. Hot swapping the fan module will not interrupt the service for any subscribers.
|
Caution The input/output (I/O) module, DSL interface module, and DC PEM are field replaceable units (FRUs); however, they are not hot swappable. The system must be powered down when these modules are replaced. These modules must be installed and removed by a trained technician only. |
The following bullets list examples of recommended installation and replacement practices for the Cisco 6015 system cards and modules.
|
Caution Any card or module that is only partially connected to the backplane can disrupt system operation. |
This section describes requirements for the site where the Cisco 6015 system will be installed. Before you install the Cisco 6015 system, ensure that all the criteria in this section are met. The section describes the following:
Proper operation of the Cisco 6015 system depends on a proper environment. This section describes environmental requirements for the site where you will install the Cisco 6015 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 commercial environment.
| Environmental Specifications | Description |
|---|---|
41 to 104ºF (5 to 40ºC)—Operating |
|
Warning To prevent the switch from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 104° F (40° C). To prevent airflow restriction, allow at least 3 inches (7.6 cm) of clearance around the ventilation openings. |
Table 2-2 provides the Cisco recommendations for temperature, altitude, and humidity conditions in an outside-plant environment.
| Environmental Specifications | Description |
|---|---|
-40 to 149ºF (-40 to 65ºC)—Operating |
|
Note Electrical equipment generates heat. Ambient air temperature might not be adequate to cool equipment
to acceptable operating temperatures without adequate circulation. Ensure that the room in which you
operate your system has adequate air circulation. The Cisco 6015 system can be used in any environment
that meets Network Equipment Building Systems (NEBS) requirements. Enclosed racks must have adequate ventilation. Ensure that the rack is not overly congested, since each unit generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. Before you install a Cisco 6015 system in an outside-plant environment, verify that the remote terminal enclosure meets the following compliance requirements: GR-487, UL 50, Type 4X, EN60529 IP 55, and NEMA 4X. The enclosure must also provide adequate cooling through the use of an appropriately sized heat exchanger or air conditioner, which dissipates the heat generated by existing remote terminal system components and by the installed Cisco 6015 chassis. |
The following practices ensure proper ventilation for the Cisco 6015 system:
The Cisco 6015 fans maintain a suitable operating temperature for the internal circuitry. Ensure that the air intake vent at the right of the chassis and the air exhaust vent at the left side of the chassis (viewed from the front) are not obstructed in any way. Figure 2-1 shows the air flow through the Cisco 6015 chassis.
|
Note Enclosed racks must have adequate ventilation. Ensure that the rack is not overly congested,
because each unit generates heat. An enclosed rack should have louvered sides and a fan to provide
cooling air. Before you install a Cisco 6015 system in an outside-plant environment, verify that the remote terminal enclosure meets the following compliance requirements: GR-487, UL 50, Type 4X, EN60529 IP 55, and NEMA 4X. The enclosure must also provide adequate cooling through the use of an appropriately sized heat exchanger or air conditioner, which dissipates the heat generated by existing remote terminal system components and by the installed Cisco 6015 chassis. |
You can install a combination of the following Cisco 6015 system components in a rack:
The Cisco 6015 system fits in either a 19-inch wide rack or a 23-inch wide rack (with extenders installed). See Table 2-3 for individual rack space requirements.
| Component | Rack Space | Height | Depth |
|---|---|---|---|
| 1An RU is equal to 1.75 inches (4.45 cm).
2Third-party POTS splitters can be used. Please verify compatibility with your Cisco representative. |
|
Note In a Cisco 6015 with a POTS splitter configuration using 4xflexis, install only one POTS splitter. In a Cisco 6015 with a POTS splitter configuration using 8xDMTs and 8xDMT over ISDNs, the system requires a POTS splitter that expands the system capacity to 48 subscriber ports. Depending on the POTS splitter selected for your configuration, the installation of an additional POTS splitter may be necessary. The 8xDMT over ISDN is designed for use in a configuration with a POTS splitter only. |
Depending on your configuration type, plan accordingly so that the rack accommodates your needs. Use Table 2-4 to calculate the rack space necessary for your Cisco 6015 system configuration.
|
Note In a commercial (central office [CO]) environment, 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 6015 system components. In an outside-plant environment, the total amount of rack space should not exceed the available space inside the equipment bay of your remote terminal enclosure (typically 26 RUs). If your total configuration exceeds the available space, either replan your configuration or use more than one equipment bay (or a larger capacity cabinet) to house the Cisco 6015 system components. |

The location of the Cisco 6015 system and the layout of your rack or wiring room are extremely important for proper system operation. Equipment that is placed too close together, inadequate ventilation, and inaccessible panels can cause system malfunctions and shutdowns, which can make maintenance difficult.
When planning your site layout and equipment locations, keep in mind the precautions that are described in the "Safety Requirements" section and the "Site Requirements" section to help avoid equipment failures and reduce the possibility of environmentally-caused shutdowns. If you are currently experiencing shutdowns or unusually high errors with your existing equipment, these precautions might help you isolate the cause of failures and prevent future problems.
The CO power source or rectifier supplies external power to the system as -48/-60V DC from the fuse and alarm panel. Power connections from the fuse and alarm panel are wired to the DC PEM in the Cisco 6015 chassis. The nominal voltage is -48V DC; the minimum operating value is -40V DC; and the maximum operating value is -72V DC.
Before you connect the system to a power source, verify that the power source is properly grounded and falls within the internal power supply rating.
Calculate the typical power requirement for each Cisco 6015 component in your configuration type. Use Table 2-5 to calculate the typical power requirement that is necessary to operate your Cisco 6015 system.
