Product Number: 6100-ST-3-DS3=
This document provides information about installing and replacing the Cisco 6100 Series system DS3 subtend host module (STM). The DS3 STM is a field-replaceable unit (FRU).
This document includes the following sections:
A subtended network configuration
The term subtending refers to the host MC, and subtended refers to the downstream MC in a subtended network.
Figure 1 shows a subtending tree. The subtending host MC at the top of the subtending tree connects directly to the ATM switch. You can have two subtended node MCs connected to the first subtending host MC located at the top of the subtending tree. One or both of these subtended node MCs can also become a subtending host MC and therefore have one or two subtended node MCs connected to them.
You can subtend an MC to three tiers, with up to six MCs, all connecting through one subtending host MC to the ATM backbone (see Figure 1).
In Figure 2, the DS3 subtend host module (STM) is installed in slot 9 of the subtending host MC. A network interface (NI) module is located in slot 10. If you have
Figure 2 shows a subtending host MC and a subtended node MC with corresponding slot number assignments.
All MCs have a system I/O card installed on the MC backplane. In addition to the system I/O card, a DS3 subtending I/O card is installed on the subtending host MC backplane.
The DS3 STM manages subscribers sent from a subtended MC and installed in slot 9 of a subtending host MC, as shown in Figure 3.
Figure 4 shows a close-up of the DS3 STM faceplate.

This section describes hardware requirements and lists parts and tools used to install the DS3 STM.
The DS3 STM is not a stand-alone product. In order for a DS3 STM to work properly on a subtending host MC, you must install both a DS3 system I/O card and DS3 subtending card.
To install or replace the DS3 STM, you need the following parts and tools:
This section covers the following topics:
Before working on the equipment, be aware of standard safety practices and the hazards involved in working with electrical circuitry to prevent accidents. Adhere to the following cautions and warnings for safe and hazard-free installation.
 | Caution Proper ESD protection is required whenever you handle Cisco DSLAM equipment. Installation and maintenance personnel should be properly grounded using ground straps to eliminate the risk of ESD damage to the equipment. Modules are subject to ESD damage whenever they are removed from the chassis. |
| Caution Installing the modules in the chassis with the power leads reversed can damage the modules. |
| Caution If the modules are installed when you apply power to the system, you could damage the modules and the chassis. |
 | Warning
Use copper conductors only. |
| Warning
A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. |
| Warning
Never install telephone wiring during an electrical storm. |
| Warning Do not reach into a vacant slot or chassis while you install or removeing a module or a fan. Exposed circuitry could constitute an energy hazard. |
| Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. |
| Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. |
| Warning The ISDN connection is regarded as a source of voltage that should be inaccessible to user contact. Do not attempt to tamper with or open any public telephone operator (PTO)-provided equipment or connection hardware. Any hardwired connection (other than by a nonremovable, connect-one-time-only plug) must be made only by PTO staff or suitably trained engineers. |
| Warning The power supply circuitry for the Cisco DSLAM equipment can constitute an energy hazard. Before you install or replace the equipment, remove all jewelry (including rings, necklaces, and watches). Metal objects can come into contact with exposed power supply wiring or circuitry inside the DSLAM equipment. This could cause the metal objects to heat up and cause serious burns or weld the metal object to the equipment. |
| Warning
Do not work on the system or connect or disconnect cables during periods of lightning activity. |
| Warning
Use caution when installing or modifying telephone lines. |
| Warning
Metal objects heat up when connected to power and ground, and can cause serious burns. |
| Warning
Secure all power cabling when installing this unit to avoid disturbing field-wiring connections. |
| Warning
Ultimate disposal of this product should be handled according to all national laws and regulations. |
| Warning This unit is intended for installation in restricted access areas. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock and key, or other means of security, and is controlled by the authority responsible for the location |
| Warning The safety cover is an integral part of the product. Do not operate the unit without the safety cover installed. Operating the unit without the cover in place will invalidate the safety approvals and pose a risk of fire and electrical hazards. |
| Warning Connect the unit only to DC power source that complies with the Safety Extra-Low Voltage (SELV) requirements in IEC 60950 based safety standards. |
| Warning This product requires short-circuit (overcurrent) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations. |
| Warning
Care must be given to connecting units to the supply circuit so that wiring is not overloaded. |
| Warning Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations. |
| Warning
Do not use a telephone to report a gas leak in the vicinity of the leak. |
| Warning Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote risk of electric shock from lightning. |
| Warning Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface. |
| Warning This is a Class A product based on the standard of the Voluntary Control Council for Interference by Information Technology Equipment (VCCI). If this equipment is used in a domestic environment, radio disturbance may arise. When such trouble occurs, the user may be required to take corrective actions. |
| Warning Do not use this product near water; for example, near a bath tub, wash bowl, kitchen sink or laundry tub, in a wet basement, or near a swimming pool. |
The DS3 STM supports hot swapping. Hot swapping allows you to remove and replace the modules without disconnecting the system power. When the system detects that a module is added or removed, it automatically runs diagnostic and discovery routines, and acknowledges the presence or absence of the module.
If an unprovisioned module is installed for the first time, the system identifies it as present but unprovisioned. Instructions for provisioning the module are found in the following guides:
The following are recommended module installation and replacement practices:
Any module that is only partially connected to the backplane can disrupt system operation.
The following sections describe how to remove and replace or install a DS3 STM.
| Caution Proper ESD protection is required whenever you handle Cisco DSLAM equipment. Installation and maintenance personnel should be properly grounded using ground straps to eliminate the risk of ESD damage to the equipment. Modules are subject to ESD damage whenever they are removed from the chassis. |
Use the following steps to remove a module from the MC:
Step 2 Lift up the ejector tab.
Step 3 Carefully slide the module out of the MC.
Either replace the module that you remove, or insert a filler faceplate in the empty slot. See the "Installing a DS3 STM" section for DS3 STM installation instructions. For filler faceplate installation instructions, refer to the Cisco 6100 Series Direct Connect Installation Guide.
| Caution Proper ESD protection is required whenever you handle Cisco DSLAM equipment. Installation and maintenance personnel should be properly grounded using ground straps to eliminate the risk of ESD damage to the equipment. Modules are subject to ESD damage whenever they are removed from the chassis. |
Use the following steps to install a DS3 STM in the MC. It is important that you accomplish each step completely before moving on to the next step.
Step 2 Vertically align the module edge with the module guides at the top and bottom of slot 9 of the MC.
