Step 5. Remove all Ethernet Switch Blades, HP bc2100 ATCA Server Blades, and any other installed
blades from the 14-Slot Shelf blade cage, and individually set aside in anti-static bags for
reinstallation in the replacement chassis (follow removal procedures in “Ethernet Switch Blade” on
page 36).
Step 6. Remove all additional blades and filler panels from the blade cage and set aside for installation in
the replacement chassis.
Step 7. If the 14-Slot Shelf is currently installed in a rack, use a mobile mechanical lifting device to support
and transport the 14-Slot Shelf to an anti-static working area for further disassembly.
WARNING Heavy lift hazard. A fully loaded 14-Slot Shelf can weight as much as 200 lbs (90 kg).
Ensure that the 14-Slot Shelf is secure and balanced on the mechanical lift before
removing it from the equipment rack.
Step 8. Remove both PEMs by following the procedures in “Power Entry Modules (PEMs) and PEM Fuses”
on page 30. Set individual PEMs aside in anti-static bags for reinstallation into this chassis
following replacement of the Backplane SEEPROM Assemblies.
Step 9. Remove both Backplane SEEPROM Assemblies, and set aside in anti-static bags for installation
into the replacement chassis (see removal procedures in “Backplane SEEPROM Assemblies” on
page 46).
Step 10. Set the defective chassis aside until replacement Backplane SEEPROM Assemblies have been
installed in preparation for return of the chassis to Hewlett-Packard.
IMPORTANT Ensure that the two replacement Backplane SEEPROM Assemblies have been
installed, and that PEMs have been reinstalled in the defective 14-Slot Shelf chassis
before it is returned to Hewlett-Packard.
Replacing the 14-Slot Shelf Chassis with Backplane
CAUTION Electrostatic Discharge Hazard. Observe all ESD safety precautions while completing this
procedure. Failure to follow ESD safety precautions could result in damage to the 14-Slot Shelf
and equipment.
NOTE Replacing the 14-Slot Shelf chassis is a completely cold- swap procedure. There are no hot-swap
requirements for this procedure.
To replace a 14-Slot Shelf Chassis with Backplane, complete the following preparation and replacement
steps:
Step 1. Ensure that the replacement 14-Slot Shelf chassis is located in an anti-static work area.
Step 2. If the replacement chassis is to be installed in a rack, ensure that the rack mounting flanges are
installed in the correct position. Position rack mounting flanges for either the 4-post or the 2-post
rack, as required.
Step 3. Install the front and rear 14-Slot Shelf cable trays using the existing cable tray mounting screws.
