3.3 Rack Mounting
The procedure for rack mounting either a master shelf or an expansion shelf
is identical.
3.3.1 Shelf
The mounting ears, as shown in Figure 3-1, can be positioned for flush
mounting or 2 inch offset mounting in either a 19 inch or a 23 inch rack.
To mount the shelf, position the mounting ears as required, then mount the
shelf in the rack according to standard company practices.

one below the TimeHub 5500, leaving enough room for cable management
and following standard company practices.
