Slot Numbering for an EX8208 Switch

An EX8208 chassis accepts eight line cards, two Switch Fabric and Routing Engine (SRE) modules, one Switch Fabric (SF) module, one fan tray, and six power supplies (AC or DC). All 11 slots for the line cards and the modules run horizontally across the front of the chassis. The fan tray slot runs vertically on the left of the chassis front. The six power supply slots run vertically across the front bottom of the chassis.
