Managing Modules

Overview

This chapter describes how to manage line modules, switch route processor (SRP)
modules, switch fabric modules (SFMs), I/O modules, and I/O adapters (IOAs) in E
Series routers.
This chapter contains the following sections:
Overview on page 355
Platform Considerations on page 356
Disabling and Reenabling Line Modules, SRP Modules, and SFMs on page 360
Disabling and Reenabling IOAs on page 362
Removing an SRP Module on page 363
Replacing Line Modules on ERX Routers, the E120 Router, and the E320
Router on page 364
Replacing IOAs on the E120 Router and the E320 Router on page 368
Software Compatibility on page 372
Configuring Performance Rate of Line Modules on ERX7xx Models and the
ERX1410 Router on page 373
Managing Flash Cards on SRP Modules on page 378
Updating the Router with JUNOSe Hotfix Files on page 392
Managing the Ethernet Port on the SRP Module on page 402
Enabling Warm Restart Diagnostics on Modules on page 404
Ignoring Diagnostic Test Failures on page 406
Monitoring Modules on page 408
When managing modules, you need to consider both software and hardware
procedures. For example, before you remove an SRP module, you must enter the
halt command to prevent damage to nonvolatile storage (NVS).
This chapter describes the software issues associated with managing modules. Each
section in the chapter covers a different topic; where appropriate, a section contains
an overview of the topic, configuration tasks, and information about monitoring the
associated settings.
