a.
The maximum operating temperature specification of the chassis is
affected by the number and location of the MSM765zls installed in
the chassis. For the 5400zl chassis, if all four (the maximum number
of MSM765zls allowed in a switch) MSM765zls are installed in the left
hand side of the chassis, the maximum operating temperature spec-
ification is set to 50°C for the chassis. If any MSM765zls are installed
on the right hand side of the chassis, then the temperature specifica-
tion for the chassis is 40°C.
A 5406zl chassis has only three slots on the left. To stay within the
50°C temperature specification, only three MSM765zls are supported
in this chassis.

For the 8212zl chassis, the maximum operating temperature
specification is 40°C.
