Inserting and Securing a Module
Inserting and Securing a Module
This section describes the procedures for inserting and securing an ATM module.
Caution: I/O modules must be installed in any of the numbered chassis slots
labeled 1 through 8. I/O modules do not fit in slots A or B. Forceful insertion can
damage the I/O module.
1 Before you install modular cards in the BlackDiamond 6800 series chassis, put on the
ESD-preventive wrist strap that is provided with the chassis, and connect the metal
end of the grounding leash to the ground receptacle located on the top-left corner of
the BlackDiamond 6800 series switch front panel.
Leave the ESD-preventive wrist strap permanently connected to the BlackDiamond
6800 series chassis so that it is always available when you need to handle
ESD-sensitive switch components.
2 Identify the chassis slot for the module. If necessary, remove the blank filler from the
slot to make room for the ATM module.
Any unoccupied module slot in the chassis should have a blank filler installed
for electromagnetic compatibility (EMC) and to ensure adequate airflow
through the chassis.
3 To insert an ATM module, use Figure 2-2 as a reference and follow these steps:
To prevent ESD damage, handle the ATM module by the metal card carrier
edges only. Never touch components on the printed circuit board or pins on
any of the connectors. Never attempt to lift or hold the module by using the
heat sinks on either of the network processors.
a Grasp the module by its front panel with one hand and place your other hand
under the edge of the metal card carrier to support the weight of the module.
b
Ensure that the module is right side up (printed circuit board, or PCB, facing to
the right) and that the ejector/injector handles are fully extended.
c Carefully align the upper and lower edges of the metal card carrier in the chassis
slot and slide the module slowly into the slot, taking particular care that the heat
sinks on the two network processors are not obstructed in any way.
d Continue sliding the module into the chassis slot until the ejector/injector
handles make contact with the front edges of the chassis slot, then stop.
