14-Slot Shelf Chassis and Backplane

Although the 14-Slot Shelf chassis with backplane is replaced as an individual FRU, the replacement 14-Slot

Shelf chassis and backplane will contain a full complement of chassis components when delivered. These

components include:

• Both Shelf Management Modules, or “Shelf Managers” (ShMMs)

• Both Power Entry Modules (PEMs)

• All Fan Modules

• Air Filter Tray and Filter Element

• The Alarm Display Panel

• The Alarm Connector Panel

• Both Chassis Data Modules (Backplane SEEPROM Assemblies)

CAUTION Possible 14-Slot Shelf chassis data loss. The Chassis Data Modules must be removed from the

defective 14-Slot Shelf and installed in the replacement 14-Slot Shelf chassis in order to retain

your 14-Slot Shelf chassis configuration data.

Removing the 14-Slot Shelf Chassis and Backplane

CAUTION Possible 14-Slot Shelf chassis configuration data loss. In order to retain original chassis

configuration data when the 14-Slot Shelf chassis and backplane are replaced as a FRU, the

original 14-Slot Shelf Backplane SEEPROM Assemblies must be removed from the defective

chassis and installed in the replacement 14-Slot Shelf chassis.

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 Removing and replacing the 14-Slot Shelf chassis is a cold-swap procedure. There are no hot

swap requirements for this procedure.

To remove the chassis and backplane from the 14-Slot Shelf system, complete the following steps (refer to

Figure 1-17 and Figure 1-18):
