Subtended Network Configuration Overview
General Maintenance Guidelines
This section covers the following topics:
•Hot-Swapping Line Cards, page 9
•Installation and Replacement Suggestions, page 9
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.

Subtended Network Configuration Overview
A subtended network configuration supports the following features:
•The capacity to run data as fast as the speed of its subtended link. Uplink speed cannot exceed the
OC-3 speed.
•Four arbitration priorities, one for each quality of service (QoS) level. The supported QoS service
levels are
– Constant bit rate (CBR) for rate-limited services that require guaranteed bandwidth and
bounded delay
– Variable bit rate-real time (VBR-rt) for delay-sensitive voice and video services
– Variable bit rate-non-real time (VBR-nrt) for high-priority data services
– Unspecified bit rate (UBR) for low-priority data services
•Explicit forward congestion indication (EFCI) marking for available bit rate (ABR)
service support.
•Guaranteed frame rate (GFR).
•Tree or daisy chain configurations for DS3 subtended Cisco 6130 chassis.
•Daisy chain configurations for OC-3 subtended Cisco 6130 chassis.
•Fair access to the trunk port for each subtended chassis.
•A network trunk port that operates as fast as any subtended link.
The NI-2 card provides three types of subtended network connections:
•A high-speed OC-3 optical ATM interface that supports single-mode fiber (SMF)
intermediate range
•A high-speed OC-3 optical ATM interface that supports multimode fiber (MMF) short range
•A DS3 ATM interface
The following sections detail the three types of subtending network connections.
Subtended Network Configuration with DS3 NI-2 Cards
In a subtended network configuration using DS3 NI-2 cards, you can subtend a Cisco 6130 chassis
to four tiers, with up to twelve chassis, all connecting through one subtending host chassis to the
ATM backbone).
Figure 1 shows typical DS3-configured Cisco 6130 systems subtended in a combined subtending tree
topology with daisy chain. The subtending host chassis at the top of the subtending tree connects
directly to the ATM switch. The middle two Cisco 6130 chassis in the lowest level are daisy chained.
TRNK 1 refers to the single network trunk or Cisco 6130 chassis subtended network interface. SBTD 2
and SBTD 3 refer to the two Cisco 6130 chassis subtended interfaces. You make network interface
connections at the system I/O card that is installed on the Cisco 6130 chassis backplane.
