Warning Read the installation instructions before you connect the system to its power source.


Warning Use copper conductors only.


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.


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 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 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 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 Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.


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 Do not use a telephone to report a gas leak in the vicinity of the leak.


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. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself.


Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages


Warning This equipment is to be installed and maintained by service personnel only as defined by AS/NZS 3260 Clause 1.2.14.3 Service Personnel.


Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.

General Maintenance Guidelines

This section covers the following topics:

Installation and Replacement Suggestions

The following examples list recommended installation and replacement practices for the 8xIDSLs.


Caution   Any line card that is only partially connected to the backplane can disrupt system operation.

Hot Swapping Line Cards

The 8xIDSL 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 8xIDSL, it automatically runs diagnostic and discovery routines and acknowledges the presence or absence of the line card.

If you remove and replace an 8xIDSL with another 8xIDSL, the newly installed line card receives the same provisioning as the original line card. The system resumes operation without any operator intervention.

If an unprovisioned line card is installed for the first time, the system identifies it as present but unprovisioned. Instructions for provisioning the line card are found in the appropriate software guide for your chassis.

Preventing Electrostatic Discharge Damage

Proper ESD protection is required whenever you handle Cisco equipment. ESD damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Use an antistatic strap when you handle any card or component.

Follow these guidelines to prevent ESD damage:


Caution   Periodically check the resistance value of the antistatic strap. Ensure that the measurement is between 1 and 10 megohms.

Removing and Installing the 8xIDSL

The following sections describe how to remove or install an 8xIDSL.


Caution   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.


Note   All cards must be fully seated in the chassis. Push on the faceplate of each card to be sure that the card is fully seated.

Removing an 8xIDSL

Complete the following steps to remove an 8xIDSL from the chassis:


Step 1   Connect a grounding strap to the ESD grounding jack on the chassis.

Step 2   Use a flat-head screwdriver to move the locking tab from the locked to the unlocked position. Be sure to turn the locking tab so that it does not overlap the line card ejector lever as shown in Figure 2.


Figure 2: Positioning the Locking Tab for the 8xIDSL


Step 3   Lift the ejector lever to disconnect the line card from the backplane.

Step 4   Carefully slide the line card out of the slot.

Either replace the line card that you remove, or insert a blank faceplate in the empty slot. See the "Installing an 8xIDSL" section for 8xIDSL installation instructions. See the "Installing a Blank Faceplate" section for blank faceplate installation instructions.


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.


Installing an 8xIDSL

Complete the following steps to install an 8xIDSL in the chassis:


Step 1   Connect a grounding strap to the ESD grounding jack on the chassis.

Step 2   Hold the line card vertically, with the faceplate toward you and the connectors facing the chassis slot.

Step 3   Align the line card edges with the guides at the top and bottom of the slot in the chassis.

Step 4   Lift the ejector lever and gently apply pressure to the faceplate while pushing the line card into the slot.

Figure 3 shows an example of the 8xIDSL installation. The installation procedures will be similar for the other chassis.


Figure 3: Installation of the 8xIDSL


Step 5   Push on the faceplate of the line card to fully seat the card.

Step 6   Press down on the ejector lever to secure the line card and connect it to the backplane.

Step 7   Use a flat-head screwdriver to turn the locking tab so that it overlaps the line card ejector lever to prevent inadvertent dislodging. Figure 2 shows how to position the locking tabs.

Step 8   Verify that the STATUS LED is solid green after the brief self-test. If the STATUS LED is not green after the self-test, see the appropriate hardware guide for your chassis for troubleshooting procedures.


Note   If you are installing the line card for the first time, refer to the provisioning procedures in the appropriate software guide for your chassis.


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.

Step 3   Lift the ejector lever and gently apply pressure to the faceplate while pushing the blank faceplate into the slot.

Step 4   Push on the faceplate to fully seat the blank faceplate.

Step 5   Press down on the ejector lever to secure the faceplate.


Traffic Handling

The maximum downstream rate per port for the 8xIDSL is 144 kbps. The maximum upstream rate per port is 144 kbps.

Downstream refers to data that is coming from the NI-2 card to the subscriber lines. Upstream refers to data that is coming from the subscriber lines to the NI-2 card.
