Installing and Removing Motherboards and Processor Cards
Installing and Removing Motherboards and
Processor Cards
The mux/demux motherboards, line card motherboards, and processor cards are
hot-swappable. We recommend installing the processor cards first and then filling
the chassis from slots 0 to 11, left to right. This section describes the procedures
for installing and removing the motherboards and processor cards from the
chassis.
Installing Mux/Demux Motherboards and Processor Cards
To install a mux/demux motherboard or processor card, follow these steps:
Step 1
Remove the failed motherboard, processor card, or filler motherboard from the
shelf. See the
“Removing Mux/Demux Motherboards and Processor Cards”
Step 2
Take the new motherboard or processor card from the shipping container.
Step 3
Insert the motherboard or processor card carefully into the chassis slot while
guiding the upper and lower edges of the motherboard or processor card in the
tracks until its connectors come into contact with the backplane.
Step 4
Use your thumb and forefinger of each hand to simultaneously push the
motherboard or processor card in until it is fully seated in the backplane
connector.
Step 5
Use a 3/16-inch flat-blade screwdriver to tighten the captive installation screws.
After the system is powered up, you can check the LEDs to ensure proper
installation. See
for mux/demux motherboard LED
descriptions and
for processor card LED descriptions.
Save the filler motherboards with the packaging material.
