Safety Guidelines
Before and during the installation process, observe the following
precautions:
Lightning Activity Warning: Do not work on the system or connect or disconnect
cables during lightning activity.
DC Power Disconnection Warning: Before powering on the E-series router,
remove power from the DC circuit by deactivating the circuit breaker on the panel
board that services the DC circuit.
Jewelry Removal Warning: Remove jewelry (including rings, necklaces, and
watches) before working on equipment that is connected to power lines. Metal
objects heat up when connected to power and ground and can cause serious
burns or become welded to the terminals.
Metal Objects Warning: Do not insert any metal object, such as a screwdriver,
into an open slot or the backplane. Doing so may cause electric shock and serious
burns.
Repair 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.
Installing SRP I/O and SRP Modules
SRP modules should be installed in specific slots in each router. See
Table 5-2 for SRP module slot assignments.
Note: Because of different physical dimensions and switch fabric capabilities, SRP
modules are not interchangeable between systems. For example, the 10-Gbps
SRP module used in ERX-7xx/14xx models cannot be used in an ERX-310 router,
and vice versa.
Note: Install the SRP I/O module before you install the SRP module; otherwise, the
system diagnostics will fail.
