Brocade DCX 8510-4 Backbone Hardware Reference Manual - Manual (Page 66)

Follow electrostatic discharge (ESD) precautions when removing a blade. Wear a wrist grounding
strap connected to chassis ground (if the Brocade DCX 8510-4 is plugged in) or a bench ground.
DANGER
For safety reasons, the ESD wrist strap should contain a series 1 megaohm resistor.
NOTE
Before removing any cables from a blade, note the cable order (identify each cable by its physical
port). It is a good practice to keep a table of cable to port mapping.
NOTE
If multiple blades are being replaced, replace one blade at a time.
1. Remove the chassis door.
2. Check the power LED, status LED, and port status LED to identify any possible problems. A failed
port or application blade can be identified by inspecting the LEDs on the front panel of each blade.
3. Establish a Telnet or console session.
Before replacing a blade, establish a Telnet or console connection to determine a failure and verify
operation after replacement. Use the switchShow command to view the status of the blades.
4. Check for adequate cable slack. Ensure there is plenty of cable slack to remove a blade without
cable obstruction.
5. Ensure that the part number on the unit being replaced matches the replacement part number. The
chassisShow command displays information about the blades, including part numbers (xx-
xxxxxxx-xx), serial numbers, and additional status.
6. Ensure that traffic is not flowing through the blade (port status LED should be off) prior to
disconnecting cables.
7. Ensure that traffic is not flowing through the blade.
8. Disconnect all cables and transceivers from the blade. For mSFP transceivers (FC8-64 only), it is
recommended that you use the pull tab to remove the transceiver from the blade.
9. Unscrew the two thumbscrews from the ejectors on the blade using the Phillips screwdriver.
Unscrew the left thumbscrew until it pops out. This initiates a hot-swap request.
10.Wait for the power LED to turn off in response to the hot-swap request before removing the blade.
11.Open the ejectors by rotating them toward the center of the blade face. Pull the blade out of the
chassis using the ejectors.
12.If the blade is not being replaced by another blade, install a filler panel.
