[ANSS-netops] Replacement for motorola 300/320 FRAD

[David S. Croker]

Hi Rayo,

We are using a Cisco 1602R router.  I don't believe they are 
available as new product from Cisco anymore, but there are plenty 
still available.

1) low power -- 325ma at 12V, or around 4W
2) field hardened -- well, sort of.  We've had some failures over 
time, but surprisingly few given the fact that they are not made to 
be is an unsealed vault in the middle of nowhere.
3) uses 110V AC or 12V DC power -- either.  Like Kyle says, the plug 
is of an unknown type.  We just cut the brick off and put spade lugs 
on for 12V solar operation.  Now that I look at it, it kind of looks 
like an "S-video" plug, but that would be hard to believe.
4) capable of SLIP and Ethernet -- definitely Ethernet, but I can't 
say anything about SLIP.
5) easy to setup, use standard templates possibly browser-based -- 
difficult to set up, although we have written up a cheat sheet on all 
the steps you need to follow to do so.
6) remotely monitored via SNMP -- can't say
7) reasonably priced or available as used -- Last time we purchased 
them for only $50/ea from a used outlet in Santa Barbara called 
Network Hardware Resale.  There are other vendors out there too.

For the SLIP and SNMP questions, you might try Will Kohler in our 
office.  He might know.  There is room for an extra WIC card for 
expansion if necessary.
