An OC48 line module spans two slots in an ERX1440 router. You can install this line
module only in slots 2–3 and slots 4–5. Other slots in the system do not support this line
module.
The corresponding OC48 Frame APS I/O module spans only one slot. Install the I/O
module in the lower of the slots (either slot 2 or slot 4) that the line module spans.
The ERX1440 router with the SRP-40G+ SRP module supports GE-2 line modules in all
slots; however, full bandwidth is delivered only when the line module is in slot 2 or slot
4. The line module can be used with other SRP modules, but maximum line performance
will not be achieved.
The ERX310 router with the SRP-SE10G SRP module supports GE-2 line modules in both
slots (1 and 2). Maximum line performance is achieved in either slot.
Other ERX routers do not support GE-2 line modules.
For information about software procedures associated with replacing and managing
modules, see JunosE System Basics Configuration Guide, Chapter 6, Managing Modules.
All ERX routers support hot-swapping of modules. Hot-swapping enables you to add or
remove a module without powering down the system.
Each ERX chassis has an ESD (electrostatic discharge) grounding jack. See Table 3 on
page 35 for locations. To prevent damage from electrostatic discharge, connect an
antistatic wrist strap to the jack when handling components.
