Hi All,

I hope some knowledgeable individual can give me some guidance on an ERX
1410 question....

I have a DPFE Line card & I/O which boots correctly under version 2.61(yea
I'm not kidding it's really that old) however when I attempt to move the
line card & I/O to a chassis with OS ver 5.1.3 it does not come up. 

A "Show version" command indicates the card is booting but it never
completes (and never fails). The mem on the line card under 2.6.1 showes to
be 64 Meg.

I know the Dual Port Fast Ether line card is EOL with version 7.x but I only
need to get it to 5.1.3 right now. 

Can anyone tell me what my issue might be? 

Does the card require 128 Meg of mem to boot under 5.1.3?

Any guidance would be most appreciated.

Thanks for your consideration,

Rocco

Hi,

Wow that is old; I remember when 2.X came out for JUNOSe (UNISON as  
the time). There may be an issue in the upgrade process for such an  
old card. You can always console the line card directly (with a  
straight through ribbon cable or even a regular ethernet cable on the  
diag port if you remove a faceplate next to the line card) ...

Then when the card is booting up it should show where it is failing.  
Likely it is during the POST or diag steps.

Check out juniper KB 1760 which might be the issue. I remember this  
issue well, when upgrading to 3.2.X ....

If this is not the issue, you still will find more information that  
will lead you down the right path if you console the card. Also, it  
will certainly be good if you can upgrade the memory to at least 128MB.

Kind regards,
Truman

Just a note: that 128Gbps looks to me like a 'true marketing number', 
because of what ex-series show in cli is 32Gbps: 

snar at Switch> show interfaces vcp-0    
Physical interface: vcp-0, Enabled, Physical link is Down
  Type: 105, Link-level type: 70, MTU: 1514, Speed: 32000mbps

Well, there are two virtual-chassis interfaces, and they have
both input and output directions, and 32G * 2 * 2 is really 128Gbps
of marketing... 

Or am I wrong, and virtual-chassis really can do 128Gbps full-duplex 
on both ports ? And, anyway, 32Gbps is still better than 10Gbps
and saves uplink ports.

You are right.  The rear VC ports are PCI-Express 2.0 x8 ports, giving 
500 Mbytes/sec/lane * 8 lanes * 8 bits/byte = 32 Gbps per direction 
[1].

Right, Unisphere was the company, but the software used to called  
UNISON before JUNOSe. Just some trivia between beers...  ;)

Unisphere, actually. Although, the box still identified itself as
a Redstone at the time :)

The procedure of running with a faceplate removed has been described
as turning the ERX into a very expensive vacuum cleaner by my
favourite Unisphere SE :)

You'll also have to reset to factory defaults if starting with a
version prior to 4.0.0. See the release notes:
