Product Number: 6100-SYS-IO-3=
This document provides information about installing and replacing the Cisco 6100 Series system I/O card. The system I/O card is a field-replaceable unit (FRU) and is installed on a Cisco 6100/6130 chassis backplane in a subtended network configuration.
 |
Note Older versions of the system I/O card, the DS3 subtending I/O card, or the DS3 subtend
host module (STM) cannot be mixed with the newer versions. The system I/O card
(version 6100-SYS-IO-3=), the DS3 subtending I/O card (version 6100-ST-IO-3-DS3=)
and the DS3 STM (version 6100-ST-3-DS3=) are compatible with each other. If you mix
older versions with newer versions, the hardware components will not work properly. If you need to replace all three hardware components at the same time, follow the removal and replacement procedures provided in the DS3 Retrofit Kit Release Notes located on the World Wide Web at http://www.cisco.com/univercd/cc/td/doc/product/dsl_prod/c6100/index.htm. |
This document includes the following sections:
A subtended network configuration
The term subtending refers to the host chassis, and subtended refers to the downstream chassis in a subtended network.
Figure 1 shows a subtending tree. The subtending host chassis at the top of the subtending tree connects directly to the ATM switch. You can have two subtended node chassis connected to the first subtending host chassis located at the top of the subtending tree. One or both of these subtended node chassis can also become a subtending host chassis and therefore have one or two subtended node chassis connected to them.
You can subtend a Cisco 6100/6130 chassis to three tiers, with up to six chassis, all connecting through one subtending host chassis to the ATM backbone (see Figure 1).
In Figure 2, the DS3 STM is installed in slot 9 of the subtending host chassis. A network interface module is located in slot 10. If you have
Figure 2 shows a subtending host chassis and a subtended node chassis with corresponding slot number assignments.
All chassis have a system I/O card installed on the backplane. In addition to the system I/O card, a DS3 subtending I/O card is installed on the subtending host chassis backplane.
The system I/O card provides the following:
On the system I/O card, the receive DS3 Bayonet-Neill-Concelman (BNC) connector is designated as J4, and the transmit DS3 BNC connector is designated as J3. Figure 3 shows the system I/O card that is currently in the field.
|
Note There are two DS3 jumpers on the system I/O card. The DS3 jumpers connect the BNC shield to the chassis ground. Both the receive DS3 jumper (P2) and the transmit DS3 jumper (P1) are installed on the system I/O card when it ships. |
In a subtended network configuration, the system I/O card is attached to the Cisco 6100/6130 chassis connectors P3 and P9, two 2-mm hard metric (HM) module connectors. Figure 4 shows the location of the system I/O card in relation to the DS3 subtending I/O card on the Cisco 6100/6130 chassis backplane.
Coaxial connections for cabling are located on the system I/O card and the DS3 subtending I/O card. The transmit and receive DS3 BNC connectors on the DS3 subtending I/O card are connected to the transmit and receive DS3 BNC connectors on the system I/O card (see Figure 5). Refer to the appropriate installation guide for cabling the system I/O card in a version of the Cisco 6100 Series system that is earlier than Release 2.4.0.
