Chapter 16. Chassis replacement
Before replacing the chassis, you will need to remove all the blades and the FRUs, except the WWN cards,
from the existing chassis. You will reinstall these in the replacement chassis.
Follow the procedures in this section exactly. Follow the procedures in this section exactly. Do not begin
the removal process before you familiarize yourself with all of the steps in the procedure because you will
need to save critical device and SAN information for these components before you disconnect the chassis
from the network, fabric, and power.
After you reinstall components in the new chassis, follow the procedures exactly to reconnect the chassis
to the network, fabric, and power. Then, download firmware, if necessary, and verify the system operation
and configuration.
Note: New WWN cards are shipped preinstalled in the replacement chassis. Do not replace the WWN
cards in the replacement chassis with the old WWN cards from chassis that you are replacing. This will
result in licensing issues and return materials authorization (RMA) issues for your product. The original
license will be transferred to the replacement chassis, based on the license identification (LID) of the
new, preinstalled WWN card, through the RMA process. You should be provided a license for the new
chassis through email. If you have not received this, contact your Brocade support representative.
Before beginning these procedures, perform the following tasks:
• Place the replacement chassis in close proximity to the old chassis.
• Provide a surface on which to place the old chassis, such as a second lift or the pallet originally provided
with the chassis.
• Obtain all tools and other materials listed under "Time and items required" on page 178.
To unpack and transport the new chassis, follow procedures under "Unpacking and transporting the
device" on page 16.
Precautions specific to chassis replacement
Observe the following precautions when replacing the chassis.
When removing components, wear a wrist grounding strap connected to bench ground.
DANGER: For safety reasons, the ESD wrist strap should contain a series 1 megaohm resistor.
DANGER: Disconnect the power cord from all power sources to completely remove power from
the device.
DANGER: Use safe lifting practices when moving the product.
DANGER: Make sure the rack housing the device is adequately secured to prevent it from
becoming unstable or falling over.
