Note:
z
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.
z
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.
