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 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.

Caution Proper ESD protection is required whenever you handle Cisco equipment. Installation and maintenance personnel should be properly grounded using ground straps to eliminate the risk of ESD damage to the equipment. Cards are subject to ESD damage whenever they are removed from the chassis.

General Maintenance Guidelines

This section covers the following topics:

Installation and Replacement Suggestions

The following items are examples of recommended line card installation and replacement practices:

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 line card is straight and not at an angle when you install the line card in the slot. Installing the line card at an angle can damage the line card.
Fully depress the ejector tabs to ensure that the line card connector mates with the backplane correctly. Firmly seat the line card in the slot.

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

Hot Swapping Cards

The line cards support hot swapping. Hot swapping allows you to remove, replace, and rearrange the line cards without disconnecting the system power. When the system detects that a line card is added or removed, it automatically runs diagnostic and discovery routines, and acknowledges the presence or absence of the line card.

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 and in the"Provision the Octal-Port xTU-C Line Cards" section.

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 during handling.

Follow these guidelines to prevent ESD damage:

Always use an ESD ankle or wrist strap and ensure that it makes good skin contact.
Connect the equipment end of the strap to the ESD jack on the front left side of the chassis.
When you install a component, use available ejector levers or captive installation screws to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.
When you remove a component, use available ejector levers or captive installation screws to release the bus connectors from the backplane or midplane.
Avoid touching the printed circuit boards or connectors on the NI-2 cards or line cards.
Place a removed component board-side-up on an antistatic surface or in a static-shielding container. If you plan to return the component to the factory, immediately place it in a static-shielding container.
Avoid contact between the printed circuit boards and clothing. The wrist strap protects components from ESD voltages on the body only; ESD voltages on clothing can still cause damage.

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

Remove the Power

Complete the following steps to remove power from the Cisco 6160 system:

Step 1 Type the following command to save the configuration changes to NVRAM:

DSLAM# copy running-config startup-config

Step 2 Set the circuit breakers on the power entry modules (PEMs) to the OFF (0) position.

Measure the Rack Space and Prepare the Rack

When upgrading your system from 4xflexis to 8xDMTs in a Cisco 6160 with a POTS splitter configuration, you may have to move the hardware components in the rack to accommodate a second POTS splitter as necessary. See the "Configuration Requirements" section for additional information.

Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back.

Complete the following steps to measure the rack space and prepare the rack:

Step 1 Use Table 3 to calculate the rack space necessary for your Cisco 6160 system configuration. The total amount of rack space should not exceed 42 RUs. If your total configuration exceeds 42 RUs, either replan your configuration or use more than one rack to house the Cisco 6160 system components.

Table 3: Rack Space Calculation for the Cisco 6160 System Configurations

Line	Instructions	Calculation
1	Total number of Cisco 6160 chassis in the rack—Maximum is four chassis per rack (include subtending host and subtended node chassis).
2	Total number of POTS splitters¹ in the rack.
3	Number of RUs required for the POTS splitter².
4	Multiply 11 RUs by the total number of Cisco 6160 chassis on line 1.
5	Multiply line 2 by line 3 to determine the total POTS splitter space requirement.
6	Multiply 1 RU by the total number of Cisco 6160 chassis on line 1³
7	Add lines 4, 5, and 6 to obtain the total number of RUs needed for a Cisco 6160 with or without a POTS splitter configuration.

¹A third-party POTS splitter must be used in a Cisco 6160 with a POTS splitter configuration.
²See the documentation that accompanied the third-party POTS splitter to determine the number of RUs required. One RU is equal to 1.75 inches (4.45 cm.).
³One RU is recommended for cabling needs and intake plenum.

Step 2 Connect a grounding strap to an ESD grounding jack on the chassis.

Step 3 Move the Cisco 6160 chassis up or down in the rack to accommodate an additional POTS splitter chassis, as necessary.

a. Use a Phillips-head screwdriver to remove the mounting screws that bolt the Cisco 6160 chassis in the rack.

b. Gently move the Cisco 6160 chassis up or down in the rack to accommodate an additional POTS splitter.

c. Use the mounting screws and a Phillips-head screwdriver to bolt the Cisco 6160 in the rack.

Step 4 Move the existing POTS splitter up or down in the rack to accommodate the additional POTS splitter, as necessary.

Note For removal and installation procedures for each POTS splitter, refer to the appropriate third-party documentation.

Install the POTS Splitter

Before you install the additional POTS splitter needed for a Cisco 6160 with a POTS splitter configuration, you need to stabilize the rack for the new hardware components.

Verify that your Cisco 6160 system is installed from the bottom to the top of the rack so the rack remains stable. If your system is not installed from the bottom to the top of the rack, make the necessary adjustments to the rack.

Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

- This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

- When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

- If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

In a Cisco 6160 system with a POTS splitter configuration using 8xDMTs, it is necessary to expand the system to accommodate 256 ports in one of the following ways:

Install a 528 POTS splitter.
Verify that a total of two 128 POTS splitters are installed in the rack.

Verify the Cisco 6160 Cabling

The Champ connector pinouts on the back of the Cisco 6160 chassis are mapped for octal-port xTU-C line cards. Verify that industry-standard unshielded twisted pair (UTP) 50-pin Champ cables are currently used in your configuration. If you are making your own cables or using another type of cable, see the "Port Mapping of Subscriber Connectors to Slots and Ports" section for port mapping information.

Remove the 4xflexis

Complete the following steps to remove the 4xflexis from the Cisco 6160 chassis:

Step 1 Connect a grounding strap to an ESD grounding jack.

Step 2 Use a flat-head screwdriver to move the locking tabs from the locked to the unlocked position on the 4xflexis. Be sure to turn the locking tab so that it does not overlap the line card ejector tab, as shown in Figure 1.

Figure 1: Locking and Unlocking the Line Card

Step 3 Lift up on the ejector tab of each card. This action disconnects the card from the backplane.

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

Step 5 Repeat Steps 1 through 4 for each line card in the Cisco 6160.

Either replace the 4xflexi that you remove with an 8xDMT, or insert a blank faceplate in the empty slot. See the "Install the 8xDMTs" section for 8xDMT installation procedures. For blank faceplate installation procedures, refer to the Cisco 6160 Hardware Installation Guide.

Note Blank faceplates should occupy any empty slots in the chassis.

Install the 8xDMTs

Complete the following steps to install the 8xDMT in the Cisco 6160 chassis:

Step 1 Connect a grounding strap to an ESD grounding jack.

Step 2 Hold the 8xDMT vertically, with the line card faceplate toward you and the connectors facing the chassis slot.

Step 3 Align the line card edge with the guides at the top and bottom of the slot in the Cisco 6160.

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

Figure 2 shows the 8xDMT installation for a Cisco 6160 chassis.
