ERX Overview
CAUTION: Do not remove the SRP module while the system is running.
NOTE: Some SRP modules require a minimum amount of memory to be used
with JUNOSe Rel
ease 5.3.0 or a higher-numbered release. See the ERX Module
Guide for module specifications.
For details abo
ut installing SRP modules, see “Installing Mo dules” on page 35.
SRP Module Redundancy
SRP module redundancy is available only for ERX-7xx and ERX-14xx m odels.
See “ Redund an
cy Features” on page 16 for more information.
Nonvolatile Storage
ThePCMCIAslotonthefrontoftheSRPmoduleholdsaTypeIIPCMCIAnonvolatile
storage (NVS)
card. (See Figu re 9 an d Figure 10.) This card is loaded with th e
system’s software and configuration files. The PCMCIA card is factory installed.
CAUTION: Alth
ough you can remove PCMCIA NVS (Flash) cards from a running
router, we recommen d that you do not do so. I f you remove the card while data is
being written to or copied from the NVS card, data can be lost or corrupted.
Therefore, we
strongly recommend that you shut down the router before removing
a PCMCIA NVS card.
SRP I/O Module
The SRP I/O module is a single corresponding input/output module that interfaces
with the SRP m
odules through the system’s midplane. The same SRP I/O module
works with all SRP modules, but is router specific. The I/O module used in
ERX-7xx a nd ERX-14xx models cannot be used in the ERX-310 router, and
vice versa.
See Figure 2, Figure 4, and Figure 6 for locations.
Module Details
The SRP I/O module provides standard craft management interfaces, including:
10/100Base-T—The port enables access to the ERX router for Ethernet
management
functions via CLI or SNMP, for example.
