Chapter 1: Dell PowerConnect J-Series J-EX8208 Switch Overview Routing Engines and Switch Fabric Switching functionality, system management, and system control functions of a J-EX8208 switch are performed by the Switch Fabric and Routing Engine (SRE) module. See "Switch Fabric and Routing Engine (SRE) Module in a J-EX8208 Switch" on page 22. An SRE module contains a Routing Engine and switch fabric. The SRE modules are installed in the front of the chassis in the slots labeled SRE0 and SRE1. See "Slot Numbering for a J-EX8208 Switch" on page 11. A redundant configuration J-EX8208 switch has two SRE modules. See "J-EX8208 Switch Configurations" on page 6. The Switch Fabric (SF) module, working with the SRE module, provides the necessary switching functionality to a J-EX8208 switch. The SF module is installed in the front of the chassis in the slot labeled SF. In a redundant configuration switch, the additional switch fabric in the module provides full 2+1 switch fabric redundancy to the switch. See "Switch Fabric (SF) Module in a J-EX8208 Switch" on page 25. Line Cards The J-EX8208 switch features eight horizontal line card slots and supports the line rate for each line card. The line cards in J-EX8200 switches combine a Packet Forwarding Engine and Ethernet interfaces on a single assembly. They are field-replaceable units (FRUs) that can be installed in the line card slots labeled 0 through 7 on the front of the switch chassis. See "Slot Numbering for a J-EX8208 Switch" on page 11. All line cards are hot-removable and hot-insertable. The following line cards are available for J-EX8208 switches: • 8-port 10-Gigabit Ethernet SFP+ line card: This line card has eight 10-gigabit SFP+ ports on its faceplate in which you can install SFP+ transceivers. See "8-port SFP+ Line Card in a J-EX8200 Switch" on page 27. • 48-port 100/1000 SFP line card: This line card has 48 1-gigabit SFP ports on its faceplate in which you can install SFP transceivers. See "48-port SFP Line Card in a J-EX8200 Switch" on page 28. • 48-port 10/100/1000 RJ-45 line card: This line card had 48 10/100/1000 Gigabit Ethernet ports with RJ-45 connectors on its faceplate. See "48-port RJ-45 Line Card in a J-EX8200 Switch" on page 29. Cooling System Power Supplies The cooling system in a J-EX8208 switch consists of a hot-removable and hot-insertable fan tray. The fan tray contains 12 fans. The fan tray installs vertically on the left front of the chassis and provides side-to-side chassis cooling. See "Cooling System and Airflow in a J-EX8208 Switch" on page 38. Power supplies for the J-EX8208 switch are fully redundant, load-sharing, and hot-removable and hot-insertable field-replaceable units (FRUs). Each J-EX8208 switch chassis can hold up to six 2000 W AC power supplies. 5
