Parts and Tools Required

The following items are needed to replace a CSC:

  • Electrostatic discharge (ESD) strap
  • Replacement CSC
  • A #2 Phillips-head screwdriver


To prevent damage from electrostatic discharge, an ESD strap is provided in the accessory kit. See Connecting Electrostatic Discharge Wrist Strap on SBC 7000 to install it.

Replacing Core Server Card

Safety shield cover must be intact when system is powered on.

To replace a CSC, do the following:

  1. Backup the configuration. 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. he backup must be taken before performing any operation on the system. For detailed information, refer to Restoring SBC Configuration.
  2. Perform a graceful shutdown of the SBC 7000 series system through BMC GUI.
  3. Attach an Electrostatic Discharge wrist strap by using the ESD grounding point on the back panel of the chassis (see Connecting Electrostatic Discharge Wrist Strap on SBC 7000 for details).
  4. Remove all the existing connections from all the ports.

CRU Storage

All  SBC 7000 series CRUs are shipped in electrostatic discharge (ESD) bags and must be handled by using appropriate ESD precautions. The storage environment for these CRUs are:

  • Humidity must be less than 95% (non-condensing).
  • Temperature must be between -40C and +70C.


The ESD Susceptibility symbol warns of the presence of Sonus devices susceptible to electrostatic discharge. Do not handle equipment without wearing a properly grounded ESD wrist strap.
