|
Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. |
Proper electrostatic discharge (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.
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 6260 chassis supports hot swapping for the following cards:
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. If you remove and replace a line card with one of the same type, the newly installed line card receives the same provisioning as the original card. The system resumes operation without any operator intervention.
|
Note Hot swapping line cards interrupts service for the subscribers assigned to that line card. |
The Cisco 6260 also supports hot swapping for the DS3/2DS3 and OC-3c/OC-3c NI-2 cards. Hot swapping active NI-2 cards interrupts service for the entire system until the NI-2 card is replaced or until a redundant NI-2 takes over system operations. However, you can hot swap standby NI-2 cards without interrupting service.
Hot swapping allows you to remove and replace an I/O module without disconnecting the system power. The Cisco 6260 chassis supports hot swapping for the I/O module, but removing the I/O module interrupts the service for the entire system until it is replaced.
|
Caution The I/O module must be installed and replaced by a trained technician only. |
The following are recommended installation and replacement practices for the Cisco 6260 system cards and modules.
|
Caution Any card that is only partially connected to the backplane can disrupt system operation. |
This section describes requirements for the site at which the Cisco 6260 system is to be installed. Before you install the Cisco 6260 system, ensure that all the criteria in this section are met. The section describes the following:
Proper operation of the Cisco 6260 system depends on a proper environment. Before you install the Cisco 6260 system, ensure that all the criteria in this section are met. This section describes the following environmental requirements:
The Cisco 6260 system can tolerate a wide range of temperatures. Table 2-1 provides the Cisco recommendations for temperature, altitude, and humidity conditions in a central office (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). |
The Cisco 6260 fans maintain a suitable operating temperature for the internal circuitry. Ensure that the air intake vents at the lower front of the chassis and the air exhaust vents on the top of the chassis are not obstructed in any way.
The third-party POTS splitters do not dissipate heat and should be positioned at the bottom of the rack.
The air intake vents are located at the bottom front of the chassis, and the air exhaust vents are located on top of the chassis, as depicted in Figure 2-1.
The Cisco 6260 system fits in either a 19-inch (48.26 cm) wide rack or a 23-inch (58.42 cm) wide rack, if extenders are installed. See Table 2-2 for individual rack space requirements.
The Cisco 6260 chassis is 23.5 inches (59.69 cm) in height and 10.86 inches (27.58 cm) in depth, taking 13.43 rack units (RUs) of space per chassis. (An RU is equal to 1.75 inches or 4.45 cm.)
|
Note Refer to the appropriate vendor documentation for the dimensions of the third-party POTS splitter. |
Depending on your configuration type, plan accordingly so that the CO rack accommodates your needs. Use Table 2-2 to calculate the rack space necessary for your Cisco 6260 system configuration.
