WARNING: Do not insert any metal object, such as a screwdriver, into an
open slot or the midplane. Doing so can cause electric shock and serious
burns.
WARNING: Never attempt to repair parts of modules yourself. Only trained
customer service personnel are authorized to service parts. Call Juniper
Networks Customer Service to make arrangements to return defective
modules for repair.
You must install SRP modules in slot 6 or slot 7, and SFM modules in slots 8, 9, or 10.
Four of the five fabric slots (SRP and SFM modules) must have a module installed for
the router to function. A minimum system configuration requires all three SFMs and at
least one SRP module to be installed. See "Fabric Slices" on page 9 for more information.
To install an SRP module or SFM module:
Ground yourself by using an antistatic wrist strap or other device and connect it to

one of the ESD grounding jacks on the chassis.
Choose the slot in which you want to install the module.
