Unpacking Line Cards, RCBs, and Switch Fabric Boards
Line cards, additional Routing and Control Boards (RCBs), and Switch Fabric Boards (SFBs) components
are field-replaceable units (FRUs) that are shipped separately from the router chassis. The RCBs and line
cards are housed in rigid sheet-metal structures. SFBs have an exposed printed circuit board on one side
and sheet metal on the other. All these components are shipped in a cardboard carton, secured with packing
material.
CAUTION: The components are maximally protected inside the shipping carton. Do not
unpack them until you are ready to install the components in the router chassis.
Before you unpack a component:
•
Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage.
See “Prevention of Electrostatic Discharge Damage” on page 343 .
•
Ensure that you know how to handle and store the component. (See “Handling and Storing MX10008
Line Cards, RCBs, and SFBs” on page 244 ).
To unpack an RCB, SFB, or line card, (see Figure 50 on page 136 ):
1. Move the shipping carton to a staging area as close to the installation site as possible.
2. Position the carton so that the arrows are pointing up.
3. Open the top flaps on the shipping carton.
4. Pull out the packing material that holds the component in place.
5. Remove the component from the electrostatic bag.
6. Save the shipping carton and packing materials in case you need to move or ship the RCB, SFB, or line
card later.
