When a switchover subsequently occurs, the redundant SRP module reloads with
the running configuration and takes the primary role. For more information about
the boot config command, see Booting the System in the JUNOSe System Basics
Configuration Guide.
Installing a Redundant SRP Module
You can install a redundant SRP module into a running router, provided that the
redundant SRP module has a valid, armed software release on its NVS card. Access
to a software release in NVS ensures that the redundant SRP module can boot; the
release need not be the same as that on the primary SRP module.
WARNING: Do not insert any metal object, such as a screwdriver, or place your hand
into an open slot or the backplane when the 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
router's ESD grounding jack, and hold modules by their edges. Do not touch the
components, pins, leads, or solder connections. These actions help to protect modules
from damage by electrostatic discharge.
To install a redundant SRP module into a running router, follow these steps:
1.
2.
3.
NOTE: The SRP module reboots after synchronization is complete.
reload slot
Install the redundant SRP module into the open SRP slot (slot 6 or 7 for ERX14xx
models, the E120 router, and the E320 router; slot 0 or 1 for ERX7xx models).
For detailed information about installing the SRP module, see the ERX Hardware
Guide or the E120 and E320 Hardware Guide.
Wait for the redundant SRP module to boot, initialize, and reach the standby
state.
When the module is in standby state, the REDUNDANT LED is on and the ONLINE
LED is off. If you issue the show version command, the state field for the slot
that contains the redundant SRP module is standby.
Synchronize the NVS file system of the redundant SRP module to that of the
primary SRP module.
Use to reboot a selected slot on the router.
If you specify a slot on the E120 or E320 router that contains an SRP module,
you reboot the SC subsystem on that slot by default. You do not, however, reboot
the fabric slice that resides on the slot.
