Upgrading a System That Contains Two SRP Modules

In a system that contains two SRP modules, you can upgrade the NVS cards
on the SRP modules without powering down the system.
WARNING: Do not insert any metal object, such as a screwdriver, or place your
hand into an open slot or the backplane when the E-series router is on. Remove
jewelry (including rings, necklaces, and watches) before working on equipment that
is connected to power lines. These actions prevent electric shock and serious burns.
CAUTION: When handling modules, use an antistatic wrist strap connected to the
E-series router's ESD grounding jack. This action helps to protect the module
from damage by electrostatic discharge.
