Disconnect the Rack Rear Support from the Rack Adapter Brackets by removing two Philips screws on each side of the .
Do not remove screws attaching the Rack Adapter Brackets to the rack until after removing the chassis from the rack.
Supporting the chassis from the bottom, remove the mounting hardware from the front rack ears. Slide the forward off the Rack Adapter Brackets. Remove the Rack Adapter brackets from the rack by removing the four rack mounting screws, two each side.
The new license bundle must be applied on the currently standalone active system before powering on the replacement system with your SSD hard drive.
The licenses must be applied on the standalone active system before bringing up the replacement system online.
The new license bundle must contain the new serial number from the replacement chassis. Call Technical Support to re-generate the license. The serial number of the new chassis is necessary to generate the license. This number can be found on the sticker behind the front Bezel. Technical Support generates the license once the RMA is submitted.
For details on rack mounting procedures, refer to Rack Mounting the SBC 5400 Chassis.

Push all SFPs into the chassis until you hear a “click” sound.
For more information on installing the SFPs, refer to the section SBC 5400 SFPs.
The replacement chassis is shipped with a pre-installed SSD. When the chassis RMA is performed, the customer receives the SSD with a pre-installed older release. The procedure to install an SSD hard drive to the chassis is:
SSD Received with new Chassis:
Configure the Management port IP addresses.
Update the BIOS Firmware.
For more information, see section Firmware Configuration and Upgrade.
The data on your SSD drive can be corrupted if the BMC and BIOS versions do not correspond to the version.
Insert the Original SSD:
Plug the required cables to the new chassis. Make sure all the cables are plugged in according to the labeling.
The BMC/Management cables must be connected before upgrading the BIOS and BMC.
The Packet cables must be connected once:
The following procedure explains how to connect to the power and powering on the switch:
Turn on your local AC power source.
Turn on your local DC power source.
This is applicable for SBC 5x10 series. For more information on DSP card installation, refer to the sections SBC 5400 DSP20 Module and SBC 5400 DSP25 Module.
The installation process is divided into following parts. New license, BMC, and BIOS must be already installed or upgraded.
Ribbon provides the pre-configured IP address “169.254.77.1” to facilitate out of the box access to the BMC web interface. Configure your PC to access the default BMC address “169.254.77.1”. To access the BMC web application, connect the Field Service Port to the PC configured with the pre-configured IP address and type the IP address in a web browser.
For details, refer to the section Configuring SBC 5400 BMC IP Address Via Serial Console or Launching the SBC 5400 BMC Remote Console.

During installation of the application, the local host role must be carefully entered. The local host role depends on what the system (being replaced) was originally configured for. For example if it was originally the active system. So the local host role must be configured as active.
The system status can be checked by using EMA GUI or by CLI commands.
Using EMA GUI
For detailed information, refer to All - System.
Using CLI
The following commands must be executed to check the system status:
% show table system serverStatus % show table system syncStatus
For details, refer to the section Show Table System.
As part of the application install, the system will reboot. After reboot, the standby system starts to sync with the active system automatically. The sync process can take approximately 30 to 40 minutes. The sync and server status can be monitored through CLI/EMA/EMS on the active system.
