Connecting Extension Chassis

The FB3000 8-slot chassis supports up to 3 additional chassis. When connecting an
extension chassis to the "base" chassis (the chassis containing the CPU module), use only
the right-hand side of the base chassis. The FB3000 base chassis cannot support an
extension chassis using the left-hand connector.
The FB3000 4-slot chassis can serve as a single base chassis, or as the last extension
chassis in an 8-slot chassis assembly. The FB3000 4-slot chassis cannot have an extension
chassis since it has no right-hand connector.
EXPLOSION HAZARD - MAY CAUSE DEATH
When installing in a hazardous location, the installer must ensure the side connectors
between the chassis are fully engaged.
Failure to do so may result in death or serious injury to personnel.
MAY CAUSE INJURY TO PERSONNEL AND EQUIPMENT
When mounting an FB3000 with one or more extension chassis in an enclosure, ensure
that you mount the racks in a left to right horizontal direction (wall mount on DIN-
rails) inside the end user system enclosure to allow for adequate heat dissipation.
Never mount the racks in a vertical stacked direction.
Notes
If using multiple chassis, the length dimension increases by approximately 220 mm (8.7
in) for each additional chassis 8-slot chassis, so:
If using multiple chassis, the length dimension increases by approximately 220 mm

(8.7 in) for each additional chassis 8-slot chassis
If using two 8-slot chassis, overall length is approximately 465 mm (18.30 in)

If using three 8-slot chassis, overall length is approximately 685 mm (26.96 in)

If using four 8-slot chassis, overall length is approximately 905 mm (35.62 in)

A 4-slot chassis can serve as an extension chassis, but only as the last chassis in the

assembly, and it adds approximately 134.84 mm (5.309 in) to the length of a one, two
or three 8-slot chassis assembly.
