When we bought our system, we got it with the works, so StarACS.

Nathan, which ACS are you using? Trying to decide whether to hold out for 
Breezeview ACS or do something third-party. $$

This thread is interesting because I was just complaining last night to our 
vendor about how fragile the software on the CPE8000s seems to be.

We have not had specific issues with flashing CPEs "over the air" from the web 
interface, but sometimes ACS-initiated updates don't complete correctly.  On 
7000s it usually takes the form of the upgrade not completing and the UE 
falling off of the ACS, but the radio stays up and attached to the network.  We 
go in via the web interface OTA and reboot it and it comes back with the same 
version of firmware it was already running.  Second time is usually the charm, 
and I'm thinking that perhaps if the UE had been freshly-rebooted before 
attempting the update, we might have a higher success rate.  (We have also seen 
7000s just stop talking to the ACS without us touching the firmware, and even 
though they are otherwise working fine.  Again, rebooting the CPE fixes this.  
Although it is rare, we have seen this even on the latest .116)

We once had a 7000 that did drop off the network after pushing the update via 
ACS.  We never checked what state it was in from the ethernet side, but we had 
the customer powercycle it themselves and it came back…again running the same 
firmware.  So the upgrade did not take, but it didn't brick it either and 
resetting config to defaults on the UE was not (and at least for us never has 
been) necessary.

So we have never had to truck-roll to a 7000 as a result of a failed firmware 
upgrade.  The 8000s, however, seem to be another story.  I am so scared to 
touch the ones we have in the field anymore.  We have had a couple that seem to 
get their configs corrupted after a firmware change, and get into very funky 
states.

One of them had these symptoms: defaulted to a 192.168.0.1 IP on the ethernet 
(!), no web server running, no DHCP server running, had telnet access that 
didn't prompt for a password (!!).  Fixed it by resetting to defaults (found a 
shell script that performs this function on the CPE's filesystem).  I got lucky 
with this one.

One that I have sitting on my desk now is one that we tried to rollback the 
firmware on (customer was experiencing random network detaches, and the latest 
8000 firmware doesn't reattach for 15 minutes on-the-dot, so customer was -- I 
think justifiably -- getting a bit pissy).  Current symptoms are: NO IPv4 on 
the ethernet, IPv6 link-local responds, no web server running, no DHCP server 
running, telnet responds (calls itself "KZTECH") but default root/root123 
doesn't work, so I have NO way to get in and reset the damn thing, and the 
8000s don't seem to have a reset button.  Thus it seems that it is possible for 
a scrambled config to completely brick an 8000.

If anybody has reliable information on how to get the 8000 to wipe its config 
during bootup even though it seemingly lacks a reset button, I would be 
eternally grateful...

Hi,

So far only 1 CPE8000 UE that did not come back after a firmware update.  
Normally a hard reboot would fix it, but in this case we had to replace it.
I have that CPE8000 on my desk and need to see what the status is from the LAN 
side.  Thanks for the info on defaulting it, will try it.

Matt C.

We've had a helluva time upgrading UE firmware over the air.  It was worse with 
Wimax.  On Wimax it was more like 75% of the time we would lose the channel 
scan table and have to go on site to add it back in.  It became SOP to leave 
the operator password at default so we had the option of having the customer 
log in and fix the scan table for us.

I think we've had more success since going to LTE.  However, failed firmware 
updates was one of the incentives to set up a dedicated management bearer.  I 
was hoping it would help with these things.  We haven't pushed out an update 
recently enough to say whether it helped.

Subject: [Telrad] UE upgrade failure rate

Does anybody else experience a ten to fifteen percent failure rate when 
upgrading UEs?  The behavior is, you upgrade the firmware, reboot, and the 
device doesn’t come back.  Logging into the UE’s management from LAN, you’ll 
see it’s stuck in ‘device init.’  Defaulting the unit and rebooting allows it 
to boot and attach.

We’re not using the residential gateway device or anything, and the only config 
we put in is device name, SNMP and ACS settings.  Sometimes we hardcode the 
client’s device in the DHCP server, to turn on DMZ to allow port forwarding, 
but that doesn’t seem to be a causal factor.
