[j-nsp] Juniper M-series vs 72xx/NPE-G2

[Hyunseog Ryu]

PE-1GE-SFP   1-port GigabitEthernet PIC with SFP module required. So you 
can change cable type by switching SFP module. PE- means it can be used 
for M5/M10/M7i/M10i. 

P-1GE-SX        1-port GigabitEthernet PIC with SX optic option. And this 
can be used for M20/M40 or higher model. 

You can not use P- model PIC in M7i/M10i from support contract concern.
It is same hardware except PE- module with ejector latch. 
But If you use PE- in M20/M40 or higher, or vice versa, your support 
contract will not support that configuration. 

Also, I think P-1GE-SX is the end-of-sales. For that manner, P-1GE-SX-B 
has same boat. 
P-1GE-SX might not be supported from support contract because it was 
discontinured for long time. 
I'm not sure about P-1GE-SX-B. 

So for your option, you should look at PE-1GE-SFP with 1GE-SFP-SX or 
whatever SFP you need.

The M7i looks good, and with the trade-in program, may be within budget. 
However, the 2 GigE bundle is twice as expensive as the 2 FastE bundle. 
That 
said, we only really need 1 GigE now (with 1 FastE for backup).  What is 
the 
difference in these PICs:

PE-1GE-SFP
P-1GE-SX

I know the P-1GE-SX is older (and seems to be cheaper), but will it work 
in the 
M7i? (trying to get a GigE interface for as cheap as possible)
