Shelf Considerations
The TimeSource 3100 Shelf can be mounted in an ETSI 53.5 cm rack or a 48 cm rack. The
shelf is shipped with supplied mounting ears positioned for flush mounting on an ETSI 53.5
cm rack. Attach the mounting ears (Figure 9) to the appropriate positions on the sides of the
shelf for flush mounting or 12.7 cm offset mounting. Attach the short side of the mounting
ear to the shelf for an ETSI 53.5 cm rack, and attach the long side of the mounting ears to
the shelf for a 48 cm rack. Mount the shelf in the rack according to standard company
practices.
