Overview
For information about allowed combinations of line modules in slot groups, see
JUNOSe System Basics Configuration Guide, Chapter 5, Managing Line Modules and
SRP Modules.
The ERX-1440 router with the SRP-40G+ SRP module supports OC48 line modules.
Other E-series routers do not support OC48 line modules.
An OC48 line module spans two slots in an ERX-1440 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.
For information about software procedures associated with replacing and managing
modules, see JUNOSe System Basics Configuration Guide, Chapter 5, Managing Line
Modules and SRP Modules.
All E-series routers support hot-swapping of modules. Hot-swapping allows you to
add or remove a module without powering down the system.
Each E-series chassis has an ESD (electrostatic discharge) grounding jack. See
Table 4 for locations. To prevent damage from electrostatic discharge, connect an
antistatic wrist strap to the jack when handling components.
