Introduction Introduction The 8xDMT is designed for use in one of the following system configurations: • With a POTS splitter chassis—Provisions one modem directly and is physically connected to one specific subscriber line through the POTS splitter chassis. • Without a POTS splitter chassis—Provisions one modem directly and is physically connected to one specific subscriber line through the main distribution frame (MDF) connections. The 8xDMT • Supports eight ADSL modem connections.

Part and Tool Requirements Part and Tool Requirements Table 4 lists the tools and equipment that you need to install and remove a 8xDMT. Table 4 Check Tool and Equipment Requirements Checklist Tools and Equipment 8xDMT—Commercial or outside-plant version. Equipment necessary for ESD protection—You need this equipment whenever you handle Cisco chassis, modules, and cards. Flat-head screwdriver. Note The system has no internal user-serviceable parts.

General Safety Precaution and Maintenance Guidelines Caution If the power connections are improperly connected and power is applied while the cards are installed, the cards and chassis could be damaged. Caution Service is interrupted only for the subscribers assigned to the line card that is being removed. Caution It is important that the chassis cooling fans run continuously while the system is powered. Caution Any card that is only partially connected to the backplane can disrupt system operation.

General Safety Precaution and Maintenance Guidelines Warning Never install telephone wiring during an electrical storm. 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.
PAGE 10
General Safety Precaution and Maintenance Guidelines Warning Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface. Warning Do not use this product near water; for example, near a bathtub, washbowl, kitchen sink or laundry tub, in a wet basement, or near a swimming pool. Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card.

General Safety Precaution and Maintenance Guidelines Hot Swapping Line Cards The 8xDMT can be hot swapped. Hot swapping allows you to remove, replace, and rearrange the line cards without disconnecting the system power. When the system detects that you have added or removed an 8xDMT, it automatically runs diagnostic and discovery routines and acknowledges the presence or absence of the line card.
PAGE 12
Removing and Installing the 8xDMT Removing and Installing the 8xDMT The following sections describe how to remove or install an 8xDMT. Caution Note Proper ESD protection is required whenever you handle Cisco equipment. Installation and maintenance personnel should be properly grounded by means of grounding straps to eliminate the risk of ESD damage to the equipment. Equipment is subject to ESD damage whenever it is removed from the chassis. All cards must be fully seated in the chassis.
PAGE 13
Removing and Installing the 8xDMT Installing an 8xDMT Complete the following steps to install an 8xDMT in the chassis: Step 1 Connect a grounding strap to the ESD grounding jack on the chassis. Step 2 Hold the line card horizontally (Cisco 6015) or vertically (Cisco 6160 or Cisco 6260), with the faceplate toward you and the connectors facing the chassis slot.
PAGE 14
Traffic Handling Installing a Blank Faceplate Complete the following steps to install a blank faceplate in the chassis: Note Blank faceplates should occupy any empty line card slots in the chassis. The blank faceplate installation is similar to the line card installation. Step 1 Connect a grounding strap to the ESD grounding jack. Step 2 Align the blank faceplate edges with the slot guides in the chassis.
