Product Overview
Product Overview
This section describes the top and bottom front chassis panels and the LED board.
Top and Bottom Front Chassis Panels
The top and bottom front chassis panels each comprise a plastic injected-molded bezel on a metal frame. The top front panel covers the entire front chassis opening and attaches to the bottom of the
chassis frame with two captive screws. (See Figure 1)

The lower section of the top front panel houses the air filter, which cleans intake air drawn in by the blower. Three cutouts in the top of the panel contain semiopaque black plastic windows, through which the three system
LEDs are visible when they are on. EMI shielding surrounds the entire outer edge of the top front panel. The shielding acts as a spring, and compresses when you push the panel into the chassis to keep the panel fitted tightly into the chassis opening.
The bottom front panel is vented and covers the lower area of the top front panel that houses the air filter. The bottom front panel fits over the lower section of the top front panel and attaches to the chassis with ball studs. You must remove the bottom front panel before you can remove the top front panel. You can remove the bottom front panel while the system is operating to access or clean the air filter, but always turn system power off before removing the top front panel.
The chassis panels provide shielding against electromagnetic interference (EMI) and work with the blower and air filter to maintain a constant flow of cooling air through the chassis. Replace the chassis panels if they become warped or broken.

Prerequisites
Safety Guidelines
The following guidelines will help to ensure your safety and protect the equipment. This list is not inclusive of all potentially hazardous situations, so be alert.
•
Always turn all power supplies off and disconnect power cords before removing the top front chassis panel. Dangerous current levels are present on the backplane when power is on.
•
Do not work alone when potentially hazardous conditions exist.
•
Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.
•
Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.
•
Never assume that power has been disconnected from a circuit; always check.
In addition, use the guidelines that follow when working with any equipment that is connected to telephone wiring or other network cabling.
•
Never install telephone wiring during a lightning storm.
Warning
Do not work on the system or connect or disconnect cables during periods of lightning
•
Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
•
Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
•
Use caution when installing or modifying telephone lines.
Warning
Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages. (For translation of this safety warning, refer to the section
“Chassis Warning—Disconnecting Telephone-Network Cables” on page 15.)
Caution
Always handle an LED board by the edges only; avoid touching the board components, traces, or connector pins.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which occurs when electronic boards or components are improperly handled, can result in complete or intermittent failures. The processor modules each comprise a printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and a handle are integral components of the carrier. The LED board, however, is not intended to be handled and has no frame or shielding. Handle the LED board by the edges only; never touch the board components, traces, or connector pins.
Following are guidelines for preventing ESD damage:
•
Always use an ESD strap and ensure that it makes good skin contact.
6 Cisco 7000 and Cisco 7507 LED Board Replacement Instructions
Removing and Replacing the Front Chassis Panels
•
When removing or installing an LED board, connect the equipment end of the ground strap to an unpainted surface of the chassis, such as the vertical metal frame that is exposed when the front chassis panels are removed.
•
Handle boards by the edges only; avoid touching the board components, traces, or connector pins.
•
Place a removed board component-side-up on an antistatic surface or in a static shielding bag. If you are returning the board to the factory, immediately place it in a static shielding bag to avoid
ESD damage.
•
Avoid contact between the board and clothing. The wrist strap only protects the board from ESD voltages on the body; ESD voltages on clothing can still cause damage.
Note
For safety, periodically check the resistance value of the antistatic strap. The measurement should be within the range of 1 and 10 megohms.
List of Parts and Tools
You need the following tools to replace a front chassis panel or an LED board:
•
If you are replacing the top front chassis panel or the LED board, you need a 3/16-inch flat-blade or Number 2 Phillips screwdriver to remove the top front chassis panel. Earlier chassis (the first several hundred shipped) used slotted screws, and later chassis used Phillips screws to secure the top front panel to the chassis.
•
If you are replacing an LED board, you need an antistatic mat, foam pad, or bag for the removed board (immediately place a removed board into an antistatic bag if you will return it to the factory)
No tools are required to remove or replace the bottom front panel or the LED board.
Removing and Replacing the Front Chassis Panels
You must remove the top and bottom front chassis panels to access the chassis interior to replace the
LED board. Carefully follow the instructions for removing and replacing the top front panel; you can damage or destroy the LED board or top front panel by forcing a misaligned panel onto or off of the chassis body.
Warning
Before working on a chassis or working near power supplies, unplug the power cord on
AC units; disconnect the power at the circuit breaker on DC units. (For translation of this safety
warning, refer to the section “Power Supply Disconnection Warning” on page 16.)
Warning
This unit might have more than one power cord. To reduce the risk of electric shock, disconnect the two power supply cords before servicing the unit. (For translation of this safety
warning, refer to the section “Electric Shock Warning” on page 17.)
Note
The following warning is for units with DC-input power supplies.
Cisco 7000 and Cisco 7507 LED Board Replacement Instructions 7
Removing and Replacing the Front Chassis Panels
Warning
Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. (For translation of this safety warning, refer to the section
“DC Power Disconnection Warning” on page 17.)
Removing the Panels
You must remove the bottom front panel before you can remove the top front panel. The plastic bottom front panel is attached to the chassis with ball studs. The top front panel is attached to the chassis with two captive screws. The EMI shielding around the outer edge of the top front panel acts as a spring, and compresses when you push the panel into the chassis to keep the panel fitted tightly into the chassis opening.
To remove the front panels, perform the following steps:
Step 1
Grasp the bottom edge of the bottom chassis panel.
Step 2
Pull the bottom of the panel out about one inch, then place your fingers behind the sides of
the panel and pull it off the chassis. (See Figure 5.)
Step 3
On the top front panel, use a screwdriver to loosen the two captive screws at the bottom edge of the panel frame.

Step 5
With your other hand, grasp the front of the panel by inserting your fingers into the opening
on the underside of the bezel. (See Figure 6a.)
Step 6
While pushing slightly against the top of the panel to constrain it, pivot the bottom edge of
the frame outward about two inches. (See Figure 6a.) Because of the tightly compressed
EMI shielding, you will have to use significant force to pull the bottom of the panel outward. However, be careful that you do not pull the panel more than two inches away from the chassis, or you can damage the inner bezel or LED board.
Step 7
When the bottom of the frame clears the chassis opening, keep your hands in the same
positions and pull the panel downward and off the chassis. (See Figure 6b.)
Replacing the Panels
To replace the front panels, perform the following steps:
Step 1
Grasp the sides of the top panel with both hands. (See Figure 7a on page 11.)
Step 2
Two guide tabs at the top edges of the panel fit into two slots in the top edges of the chassis opening. Tilt the top of the panel back (away from you) about 30 degrees from vertical and
slide the two guide tabs into the chassis slots. (See Figure 7a.)
Step 3
Check the top of the panel and make sure it is lined up with the top of the chassis opening.
Failure to align the panel at this point can result in equipment damage when performing the next step.
Step 4
Maintain a steady upward pressure to keep the guide tabs in the chassis slots.
Step 5
When the panel is flush against the front of the chassis, push the panel upward until the
bottom of the panel is level with the bottom of the chassis opening. (See Figure 7c.)
Cisco 7000 and Cisco 7507 LED Board Replacement Instructions 9
Removing and Replacing the Front Chassis Panels
Step 6
While holding the panel in place, place one palm against the top front center of the panel to brace it, and place the other against the lip near the bottom edge of the frame. (See
Step 7
Push the panel upward and back into the chassis opening until the tabs on the front sides of
the panel are flush against the front of the chassis. (See Figure 7e.) You will have to use
significant force to compress the EMI shielding enough to fit into the opening. If the panel resists, pull it slightly downward and make sure that the panel is lined up with the top and sides of the opening in the chassis.
Step 8
When the tabs on the front sides of the panel are flush against the sides of the chassis, tighten the two captive screws in the bottom edge of the frame.
Step 9
To replace the bottom front panel, place the ball studs on the back of the panel over the holes in the front lip of the chassis and push the panel onto the chassis until the ball studs snap into place.
This completes the chassis front panel removal and replacement procedures.

Removing and Replacing the LED Board
Installation Checkout
Perform the following steps to verify that the new LED board functions correctly.
Note
The following warning is for units with DC-input power supplies.
Warning
After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the ON position. (For translation
of this safety warning, refer to the section “DC Power Connection Warning” on page 18.)
Step 1
Turn all power supplies back ON and observe the three system status indicators on the front panel.
Step 2
When you turn each power supply ON, the corresponding upper power and lower power
LEDs on the front panel should go on for each bay in which a power supply is installed and turned ON. If any do not go on, do the following:
•
Check the AC power LED on the power supply. If it is on, suspect that the front panel
LED has failed and proceed with the installation checkout to determine if the other
LEDs go on.
•
If the AC power LED is not on, or if the DC fail LED is on, ensure that the power supply is fully inserted in the power supply bay and that the captive installation screw on the top of the supply is tightened. The switch will not turn completely to the ON (|) position unless the supply is installed correctly.
•
Ensure that the power cord is fully seated in the power supply port and that the retention clip is snapped up around the plug.
•
Check the cable connection at the power source and ensure that it is connected properly.
•
If the AC Power on the power supply still fails to go on, suspect a power supply failure.
If a second (redundant) power supply is available and functioning properly, proceed with the installation checkout.
Step 3
After the system boots successfully, verify that the front panel normal LED goes on. If it does not go on, do the following:
•
Check the normal LED on the RP (in the Cisco 7000) or the RSP2 (in the Cisco 7507).
If it is on, the system software is functioning properly. Turn all power supplies OFF and
reseat the LED board by following steps 2 through 6 in the section “Installing a New
•
If the (RP or RSP2) normal LED fails to go on, the system software has failed to boot properly. Toggle the power supplies OFF then ON again and observe the behavior of the
LEDs on the RP or RSP2, so that you can report it to a service representative if you need to call for technical assistance.
This completes the installation checkout.
