Replacement Procedures
This completes the dial-shelf interconnect cable installation procedure. To verify the installation,
continue with the Verifying and Troubleshooting the Installation section on page 5-32.
Verifying and Troubleshooting the Installation
To complete the installation, verify that the LEDs operate properly by observing the following LED
states on the dial-shelf interconnect port adapter:
The power enabled LED is on.
If the enabled LED is off, the interconnect port adapter may have pulled away from the midplane.
Reseat the interconnect port adapter in its slot.
If the enabled LED remains off, contact a service representative for assistance.
The link LED is on.
If the link LED is off, check the interconnect cable connection and tighten the jackscrews.
You can also use the show dsi command in EXEC mode to display information about the dial-shelf
interconnect port adapter.
This completes the dial-shelf interconnect port adapter installation. For hardware troubleshooting
procedures, refer to the Cisco 7206 Installation and Configuration Guide, available online at
http://www.cisco.com/univercd/cc/td/doc/product/core/7206/
Replacing the Backplane Module
The Cisco AS5800 includes a passive backplane in the Cisco 5814 dial shelf that can be ordered as a
spare. This section explains how to remove and replace the backplane in the Cisco 5814 dial-shelf
chassis.
In most cases, the Cisco 5814 dial-shelf chassis will be fully installed to include the dial-shelf controller
card and feature cards. As part of the backplane removal, unseat all cards from the dial-shelf backplane.
Warning
Before completing any of the following steps, and to prevent short-circuit or shock
hazards, 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 (O) position, and tape the switch handle of the circuit breaker
in the OFF (O) position.
Warning
When installing the unit, the ground connection must always be made first and
disconnected last.
In this section you will be instructed to perform the following actions:
1. Power off the router shelf and the dial shelf.
2. Disconnect power and alarm cables to the PEMs.
3. Unseat the dial-shelf controller cards and feature cards from the backplane.
4. Remove the PEMs, filter module, and dial-shelf back panel.
5. Disconnect the blower assembly backplane cable.
6. Unscrew the backplane and remove it from the dial shelf.
