Field Replaceable Unit Removal and Replacement

14-Slot Shelf Chassis and Backplane

Chapter 1

Step 4. Remove both PEMs from the replacement chassis.

Step 5. Remove both Backplane SEEPROM Assemblies from the replacement chassis and set aside for

installation into the defective chassis for return to Hewlett-Packard.

Step 6. Install the two Backplane SEEPROM Assemblies you removed from the defective chassis into the

replacement chassis.

Step 7. Reinstall both PEMs in the replacement chassis. Do not connect input power cables and earth

protective grounds until the 14-Slot Shelf has been installed in its operating location.

Step 8. If the replacement 14-Slot Shelf chassis is to be installed in an equipment rack, place the chassis on

a mobile mechanical lifting device for transport and support during installation of the into the rack.

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 when

installing the 14-Slot Shelf in a rack.

Step 9. Install the replacement 14-Slot Shelf chassis into its equipment rack location and secure all rack

mounting flange screws.

Step 10. Install all blades in the blade cage that were removed from the original 14-Slot Shelf chassis.

Step 11. Install all blade cage front and rear slot Filler Panels to fill all open blade cage slots. Ensure that

there are no open slots remaining in the blades cage front or back in order to maintain cooling air

plenum integrity.

WARNING Electrical Shock Hazard. Power is always present at the external power supply

cables and PEM power terminals unless the external power source is turned off.

Disable/disconnect all external power supply domain circuit breakers in the OFF (O)

position before completing any of the following steps. Failure to follow electrical

safety precautions may result in personal injury.

Step 12. Reconnect the protective earth ground lead from the installation building to the replacement

14-Slot Shelf chassis (see Figure 1-2).

Step 13. Reconnect all power supply domain leads and return cables to the replacement PEMs (see

Figure 1-2).

Step 14. Verify that all FRUs have been installed in the replacement 14-Slot Shelf chassis and backplane,

and that the cooling air plenum integrity is intact (specifically, that there are no front or rear open

slots in the blade cage).

Step 15. The replacement 14-slot Shelf chassis, components, and blades should now be ready for you to

re-configure all interconnect cables as required by your VLAN topology.

CAUTION Possible management control or data loss. Ensure the Jumpers JB141-144 on both

ShMM carriers boards are installed in the position required by your specific VLAN

topology. Refer to the

HP bh5700 ATCA 14-Slot Blade Server, Installation Guide, A Sample

VLAN Topology, Shelf Manager Configuration – eth0

for information of positioning these

jumpers.
