Installation precautions
•
Static electricity can severely damage the electronic components on the controller. When
handling and installing the controller, follow these procedures to avoid damage from static
electricity:
•
Handle the controller by its bulkhead or edges and avoid touching the components and
the circuitry on the board.
•
When installing the controller, equalize any static charge difference between your body
and the switch by wearing a grounding wrist strap and attaching it to the switch's metal
body, or by frequently touching the switch's metal body.
•
The controller has low-force, high-performance connectors. High insertion forces are not
necessary to install the controller, and should not be used.
•
Ensure the controller is fully inserted
. Press the controller into the slot until the bulkhead on the
controller contacts or is very close to contacting the front face of the switch chassis.
•
When the controller is fully inserted, screw in the two retaining screws to secure the controller
in place.
•
For safe operation, proper switch cooling, and reduction of electromagnetic emissions, ensure
that a slot cover is installed on any unused controller slot. For safety, no more than one slot
should be uncovered at a time when the switch is powered on.
•
Respect the temperature specifications for the controller.
When installing the controller into a switch, the switch can be powered on or off. The installation
procedure in this guide assumes the switch is powered on.

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

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