Time and items required
The replacement procedure for the core switch blade takes approximately 30 minutes. The following items are required for the core
switch blade replacement:
• Electrostatic discharge (ESD) grounding strap
• Workstation computer
• Replacement blade or filler panel
• #1 Phillips screwdriver
• QSFP transceivers (as needed)
• Optical cables (as needed)
NOTE
For information about the transceivers that are qualified for this Brocade device, refer to the "Installing Transceivers and Cables"
section.
Replacing a core routing blade
Use the following procedures in this section to replace routing blades.
• Preparing for replacement on page 146. Use these procedures to ensure that traffic is not disrupted through existing ICL
connections when you are replacing a core routing blade. If ICLs are not connected to the blade or traffic through ICL ports has
ceased, you can skip these procedures and go to
Removing a core routing blade on page 147.
• Removing a core routing blade on page 147. Use these procedures to remove a blade from the chassis.
• Installing a core routing blade on page 148. Use these procedures to install a blade into an empty chassis slot.
NOTE
Perform these procedures to remove and install one core routing blade at a time while chassis power is on. You must replace a
blade and ensure its operation before replacing the other core routing blade. Removing both blades will shut down the chassis.
To replace both blades at the same time, power off the chassis and follow steps under
Removing a core routing blade on page
147 and Installing a core routing blade on page 148.
Preparing for replacement
For nondisruptive replacement of a core blade, ensure that the core blade in the system that you are not replacing is active and is allowing
traffic through ICL ports to the same fabrics as ICL ports on the blade being replaced.
Use the following procedures to ensure that traffic will offload from the blade that you are replacing to the other core blade in the system
during replacement. This ensures nondisruptive impact on existing traffic flowing through the blade's ICLs. If ICLs are not connected to
the blade or traffic over blade ICLs has been halted, skip these procedures and go on to
Removing a core routing blade on page 147.
1. Ensure that Lossless Dynamic Load Sharing is enabled on each logical switch that resides on each physical switch that has ICL
connections through the core blades. Log into each logical switch using an account with admin permissions, and then enter
dlsShow .
"DLS is set with Lossless enabled" should display if Lossless is enabled.
