Juniper Networks EX8208 manual Slot Numbering for the Power Supply Slots, Psu

Chapter 1: EX8208 Switch Overview

NOTE: We recommend that you install two SRE modules for redundancy. If you install only one SRE module, we recommend that you install it in the slot SRE0. See “Installing an SRE Module in an EX8208 Switch” on page 155.

Slot SF accepts only the SF module. See “Switch Fabric (SF) Module in an EX8208 Switch” on page 28. An EX8208 switch can have either zero SF modules or one SF module based on your switch configuration. The SF module is keyed so that it does not fit in any other slot in the chassis. See “Installing an SF Module in an EX8208 Switch” on page 157.

Slot Numbering for the Power Supply Slots

The chassis has six vertical slots on its front bottom. You can install up to six power supplies (either all AC or all DC) in these slots, which are labeled PSU 0 through PSU 5 (from left to right). Table 6 on page 15 lists the slot numbers for the power supplies on an EX8208 switch. See “AC Power Supply in an EX8200 Switch” on page 40 and “DC Power Supply in an EX8200 Switch” on page 48.
