ERX 8.0.x Hardware Guide
Combinations of Line Modules In Slot Groups
For information about combinatio ns of line modules in slot groups, se e JUNOSe
System Basics
Configuration Guide, C hap ter 6, Managing Modules.
OC48 Line Modules
The ERX-1440 router with the SRP-40G+ SRP m odule su pports OC48 line
modules. Othe
r ERX routers do not support OC48 line modules.
An OC48 line mo
dule 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) th at the line m odule spans.
GE-2 Line Modules
The ERX-1440 router with the SRP-40G+ SRP module supports GE-2 line
modules in a
ll slots; however, full bandwidth is delivered only w hen 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 sup ports GE -2 line modules in
both slots (
1 and 2). Maximum line performance is achieved in either slot.
Other ERX ro
uters do not support GE-2 line m odules.
Managing Modules Using the Software
For information about software procedures associated with replacing
and managi
ng modules, see JUNOSe System Basics Configuration
Guide, Chapter 6, M anaging M od ules .
Hot-Swapp
ing Modules
All ERX rou
ters support hot-swapping of modules. Hot-swapping enables you
toaddorremoveamodulewithoutpoweringdownthesystem.
Protectin
g Modules and Slots
Each ERX ch
assis h as an ES D (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.
