Hot-Swapping Line Cards
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 a you have added or removed a
line card, it automatically runs diagnostic and discovery routines, and acknowledges the presence or
absence of the card.
Installation and Replacement Suggestions
The following examples list recommended card installation and replacement practices for the
Cisco 6130 system cards.
Caution
Any line 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.
Subtended Network Configuration Overview
A subtended network configuration
•
Services and aggregates the data from one or more remotely located Cisco 6130 chassis into a
subtending host chassis to take advantage of the data network interface on the subtending
host chassis
•
Provides additional benefits by reducing the number of ATM edge-switch ports that are required to
terminate the chassis
The term subtending refers to the host chassis, and subtended refers to the downstream chassis in a
subtended network.
