Combinations of Line Modules In Slot Groups

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.

OC48 Line 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.

GE-2 Line Modules

The ERX-1440 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 ERX-310 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 E-series routers do not support GE-2 line modules.

Managing Modules Using the Software

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.

Hot-Swapping 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.

Protecting Modules and Slots

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.
