Guidelines
Use a TELECT 2000 lb four-post rack that provides bracket holes or hole
patterns spaced at 1 U (1.75 in. or 4.45 cm) increments and that meets
the size and strength requirements to support the weight.
A U is the standard rack unit defined in Cabinets, Racks, Panels, and
Associated Equipment (document number EIA-310–D) published by the
Electronics Industry Association.
You can stack one PTX10016 router or one PTX10008 router at the
bottom of the four-post rack if:
The rack is 42 U or greater.
The rack meets the strength requirements to support the weight.
The facility can provide adequate power and cooling.
The holes in the rack mount kit are spaced at 1 U (1.75 in. or 4.45 cm),
so that the router can be mounted in any rack that provides holes spaced
at that distance.
