OC48 Line Modules
The ERX-1440 router with the SRP- 40 G+ SRP module suppo rts OC48 line
modules. Othe
r ERX routers do not support OC48 line modules.
An OC48 line mo
dule spans two slots in an E RX-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 a
ll slots; however, full bandwi dth 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 ERX ro
uters do not support GE-2 line modules.
