Removal and Replacement Procedures (RRPs)
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 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.
Note: Before removing any cables from a blade, note the cable order
(identify each cable by its physical port). If multiple blades are being
replaced, replace one blade at a time.
7. Ensure that traffic is not flowing through the blade.
8. Disconnect all cables and SFP or XFP transceivers from the blade.
9. Perform the appropriate following action based on the type of
blade:
• For PB-DCX-16P, PB-DCX-32P, PB-DCX-48P port blades, and
PB-DCX-16EB encryption blade: Unscrew the two thumb
screws from the top and bottom ejectors on the blade using the
Phillips screwdriver. Unscrew the top thumb screw until it
pops out. This initiates a hot-swap request. Adjust the ejectors
to the open position (Figure 19 on page 93).
• For PB-48K-10G-6 port blade, and PB-48K-AP4-18, and
PB-48K-18i application blades: Turn the blade off by sliding
the slider switch in the left ejector to the right, to the off
position. 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. Perform the appropriate following action based on the type of
blade:
• For PB-DCX-16P, PB-DCX-32P, and PB-DCX-48P port blades,
and PB-DCX-16EB encryption blade: Open the ejectors. Pull
the blade out of the chassis using the ejectors (Figure 19 on
page 93).
