Note:
When the depth of a switch is greater than 300 mm (11.8 in.), the front mounting
ears only secure the switch rather than bear its weight.
Guide rails purchased from H3C apply only to standard cabinets 1,000 mm (39.4 in.)
deep. Use other supports to substitute for guide rails in the case of other cabinet
depths.
