Chapter 4. Using the Dual PDI bracket
Use the ME0516 Dual PDI Card Bracket to mount a pair of PDI format cards in a 4100ESi cabinet. The two PDI
cards do not need to be of the same type or size. The Dual PDI Card Bracket uses 2 PDI spaces.
Table 6 shows the PDI format cards that mount on the bracket, the looms required for connection to the
4100ESi Panel, and any mounting limitations.

Left hand side of bay or 8U
gear plate or 15U gearplate,
see the note after this table.
1 x 734-008 Any position, any cabinet.
Cannot be used with this bracket.
Fitting the Single Media Fibre Modems on the left hand side of a 15U gearplate is possible, but
careful management of the fibre optic cable is required as they are physically close to the mains
termination block and switch. The modems cannot be fitted to the centre of the gearplate as
suitable access to the fibre optic connectors is not possible.
To fit the maximum number of PDI cards, mount 4x10” double height PDI cards. Single height PDI cards can
also be mounted on the bracket.
The positions of the PDI connectors on the bracket’s PCB determines whether a PDI card is
mounted “pointing up” or “pointing down”, see Figure 27 through to Figure 30 for examples.
PDI card mounting options
Figure 27 through to Figure 30 show examples of PDI format card mounting options and their mounting
orientation on the bracket. Fit any combination of these cards on the bracket.
