    Power supplies—You can install up to six AC or six DC power supplies in an EX8208 switch. Each power supply connects to the backplane of the chassis, which distributes the output power produced by the power supplies to different switch components.

  • Page 39: Switch Fabric Redundancy

    Switch Fabric Redundancy The switch fabric circuitry in an EX8208 switch is distributed across three modules—two SRE modules and one SF module. Any two of these three modules must be installed and functional to provide a working switch fabric with no redundancy. The third module, when present, provides partial redundancy (2+1) for the switching functionality, such that if any one of the two functional modules becomes nonoperational, the third module takes over.

To avoid damaging the line cards, follow the procedures in this topic. The procedures use the following terms to describe the four edges of the line cards: Faceplate—Edge of the line card that has connectors into which you insert the transceivers.
  • Page 263 3. Place the other hand at the bottom edge of the line card. If the line card is horizontal before you grasp it, place your left hand around the faceplate and your right hand along the bottom edge. To hold a line card horizontally: 1.
  • Page 265 CAUTION: Take care not to hit the line card against any object as you carry it. Line card components are fragile. Never hold or grasp the line card anywhere except the places mentioned in these procedures. In particular, never grasp the connector edge. See Figure 79 on page 265.

  • Page 266: Storing A Line Card

    If you must rest a line card temporarily on an edge, place a cushion between the edge and the surface. Do not stack line cards on top of one another or on top of any other component. Place each line card separately in an antistatic bag or on an antistatic mat placed on a flat, stable surface.

  • Page 267: Maintaining Line Card Cables

    If you must insert the line card into a bag by yourself: 1. Lay the line card horizontally on a flat, stable surface, sheet metal side down. 2. Orient the line card with the faceplate facing you. 3. Carefully insert the line card connector edge into the opening of the bag and pull the bag toward you to cover the line card.
