The chassis must be installed in adherence with the environmental specifications and power source requirements listed in SBC 5400 Post Installation Checklist.
The following platform details are required when submitting an RMA:
For more information on hardware platform specification, refer to SBC 5400 Hardware Platform Specifications.
Before installing a new license file, a configuration backup must be taken by using the command saveConfig
, which generates the .tar.gz
backup file prior to the replacement.
The backup must be taken before performing any operation on the system. For detailed information, refer to Restoring SBC Configuration.
The following tasks are performed for physical replacement of the failed chassis with the new one:
Before installing a new license file, a configuration backup must be taken by using the command saveConfig
, which generates the .tar.gz
backup file prior to the replacement.
The backup must be taken before performing any operation on the system. For detailed information, refer to Restoring SBC Configuration.
Perform the following steps to gracefully shut down the SBC.
shutdown -h now
command].Remove the power supplies and any DSP cards from the chassis.
Perform the following checks on all systems:
Do not continue this RMA procedure until all the above criteria are met.
Check whether all cables connected to the failed chassis are labeled correctly with the corresponding port information for unique identification during the HW swap from the failed chassis to the new chassis, and correct as needed. Label the cables that are not labeled.

For detailed information on disconnecting chassis ground, refer to the section "Grounding Chassis" in Connecting Power to SBC 5400 and Powering On.
For graceful shutdown of the system, refer to the section Graceful Shutdown of the System.
The new chassis does not include power supplies or SFPs. Transfer any usable CRUs from the failed chassis to the new chassis, as needed. Contact your
When removing electronic components, the threat of electrostatic discharge (ESD) damage is always present. Ensure you wear an ESD wrist strap before installing/removing any electronic components.
Refer to Connecting ESD Wrist Strap for help with attaching the ESD wrist strap to prevent damage to the equipment.
To remove the SSD hard drive from the chassis, refer to SBC 5400 Solid State Drive.
The SFPs are not included in a new chassis delivery. Remove the SFPs before the chassis replacement and keep them in a safe location free from dirt and ESD. To remove the SFPs from the chassis, refer to SBC 5400 SFPs.
The power supplies are not a part of the chassis delivery. They must be removed and kept in a safe place until the chassis is replaced. To remove the AC and DC power supplies, refer to sections SBC 5400 AC Power Supply and SBC 5400 DC Power Supply.
For detailed information on removing the DSP cards, refer to the sections SBC 5400 DSP20 Module and SBC 5400 DSP25 Module.
Removing the failed chassis contains these steps:
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.
Disconnecting Rack Adaptor Brackets
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.
Mounting brackets
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.
The following procedure explains how to connect the ground to the
Attach the two hole chassis ground lug PN 300-30016 to the using two flat washers PN 510-00057, two split lock washers PN 510-00056, and two hex nuts PN 511-00046 as shown in the following figure.
Chassis grounding lug location
Push both power supplies into the chassis until you hear a “click” sound.
For more information on installing the power supplies, refer to the sections SBC 5400 AC Power Supply and SBC 5400 DC Power Supply.
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.
Connecting the AC power supply
Turn on your local DC power source.
Connecting the DC power supply
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.
For details, refer to the section Configuring SBC 5400 BMC IP Address Via Serial Console or Launching the SBC 5400 BMC Remote Console.
Make sure you have access to the correct software code that the current active system is running.
Mount the USB and copy the software to the /opt/sonus/
directory of the replacement system.
The BMC firmware is updated through the following steps:
For details, refer to the section Upgrading Firmware.
The new chassis does not have management IP addresses configured. To configure management IP address, refer to Configuring SBC 5400 Platform Management Network Settings.
The SBC application must be upgraded before using the old or the new SSD. For upgrading SBC application, refer to Upgrading Firmware.
The BIOS firmware is part of the SBC application installation/upgrade package.
Install/Upgrade any platform software and then install the application software on the replacement system. For details, refer to the section Installing SBC 5400 Software.
An ISO (re-imaging) should be performed on every SBC received through Return Merchandise Authorization (RMA) process. To know more about re-installing ConnexIP OS, refer to SBC 5400 - Re-Installing ConnexIP Operating System.
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.
