Handling and Storing QFX10000 Line Cards, RCBs, and SIBs
The QFX10008 and QFX10016 chassis have several field-replaceable units (FRUs) that have fragile components. To avoid damaging the line cards, Routing and RCBs (RCBs), and Switch Interface Boards (SIBs), be sure you follow the following safe handling practices. This topic covers:
Holding Line Cards and RCBs
Pay proper attention to the way you are holding line cards and RCBs. These FRUs are installed horizontally and it is best to hold them by the sides of the units when they are not in the chassis.
When walking with a line card or RCB:
- Orient the line card or the RCB so that the faceplate is toward you.
- Grasp each side of the unit firmly as you slide the unit out of the chassis.
- Take care not to strike the unit against any object as
you carry it.
Never hold the line card or RCB by the connector edge. The connectors are fragile and the line card or RCB will not seat properly if the connector is damaged. See Figure 1.

- If you must rest a line card or RCB on an edge, place
a cushion between the edge and the surface.
Do not stack line cards or RCBs on top of one another or on top of any other component.
- Place each line card separately in an electrostatic bag or on an antistatic mat placed on a flat, stable surface.
SIBs are installed vertically and should be held vertically until they are clear of the switch before rotating them 90 degrees and placing them on an antistatic mat or placing them in an electrostatic bag for storage. See Figure 2.
The proper method of holding a SIB is to:
- Hold the SIB by the ejectors while you keep the SIB vertical, and slide the SIB about three-quarters of the way out of the chassis.
- Place one hand underneath the SIB to support it, and slide
it completely out of the chassis.
Never hold the SIB by the connector edge. The connectors are fragile and the SIB will not align and seat properly if the connector is damaged.
Do not stack SIBs on top of one another or on top of any other component.
Storing Line Cards, RCBs, and SIBs
You must store line cards, RCBs, and SIBs either in the chassis or in a spare shipping container, horizontally and sheet metal side down. Do not stack these units on top of one another or on top of any other component. Place each unit separately in an antistatic bag or on an antistatic mat placed on a flat, stable surface.
Never place any material, such as port dust caps, on top of an installed line card because the system fans can pull the material into the chassis.
Because these units are heavy, and because electrotatic bags are fragile, inserting the line card into the bag is best done with two people.
To insert a line card, RCB, or SIB into an electrostatic bag:
- Hold the unit horizontally with the faceplate toward you.
- Slide the opening of the bag over the connector edge.
If you must insert the line card, RCB, or SIB into a bag by yourself:
- Lay the unit horizontally on an antistatic mat that is on a flat, stable surface with the sheet metal side down.
- Orient the unit with the faceplate toward you.
- Carefully insert the connector edge into the opening of the bag and pull the bag toward you to cover the unit.
