LSJ Preliminary Report
Updated 12/14/15
This is a preliminary report and items will be added as I look thru the network and equipment configurations.
Dragonwave
Loftin Credentials
The system had the default credentials. This was changed, because the dragonwave radios have public 1ps, anyone from
the internet could connect and this was a big security risk in terms of someone could change settings and cause the link
to fail.
Recommendations: Credentials were changed and the Ip will be changed to private. This will restrict access to the
management to our VPN and will integrate the link to Choice Monitoring system.
Firmware Bug
Currently there are two bugs that I have identified, One is non service affecting and the following is service affecting:
I've monitoring the link since Friday and there has been two drops in the dragonwave:

Both times were due to a known bug on the firmware on the radios:

Notice:Dec 0611:21:08 C1N14DGM0075 alarm[544789-1]:
Currently LSJ Dragonwave radios are running Version 1.2.2

MI6 I 5.0.0 I Valid
This is a known issue with older version of this firmware. So far both times have been triggered by the rain (Sunday and
today) the wireless link did not drop, but due to the rain were some data errors and as the radios retransmitted the data
(this is normal behavior) this alarm is raised and crashes data communications. Once the radios are rebooted or power
cycle normal transmission begins until the next event.
Recommendation: To fix this issue a firmware upgrade needs to be done. I recommend once ViNGN is in place and this
link can be taken offline to do the following:
• Reset this link to factory defaults.
• Reconfigured to Choice Standards.
• Change Management Ips to Private IPs Choice Management.
• Upgrade firmware on both radios.
Configuration (Modulation)
The radio currently is configured to a fixed maximum speed (256 QAM 279 Megs) .
Recommendation: The link was coordinated with HAAM (Hitless Automatic Adaptive Modulation) with this feature the
link will automatically drop modulation when it cannot maintain a signal without errors. Doing this, the link will be
more stable and less susceptible to rain fade.
Alignment (Signal Strength}
The microwave link is outside of the optimal signal the coordination calls for -35.7 dBm (optimal would be +/- 4.0 dBm)
and currently the signal strength is at -40.1 dBm. This can be caused by having the LS) side of the link only at 10 ft.
When you have links so low the ground can cause interference in what is call the Fresnel Zone. Basically this zone has to
be obstruction free for a microwave link to be at its optimal. See following graph.

Recommendation: raise the link to a higher height.

Network Loop
At LSJ shelter the following equipment are installed:
• Netgear Prosafe JG5516PE
• 1 Dragonwave Compaq — Link to St Thomas
• 1Rockus AP — Looking towards 5 Palms
• 1Ruckus Bridge — Looking towards the Gym
There are 2 issues with this setup,
1) The dragonwave and the bridge are on the public side of this connection (internet) the AP (5 Palms) needs to be
on the private side (internal network). Because there is no way to have communications to the internal network
from the shelter, the AP to 5 palms was plugged into the public side of the network. This is why this AP is not
working.
2) Both the Data and Management Ethernet cables of the Dragonwave radio were plugged in to the netgear.
Creating a local network look between the Dragonwave and the Netgear. This is what created the unstable
internet connection that caused between 5%-10% packet drop and caused real time applications and services
like Netflix, Hulu, YouTube, and Etc. buffer or not to work. This can also cause websites to pause as the page
was displaying (downloading) or a lag in clicking on a link.
Recommendation: to fix the issues:
• Issue Al to fix the AP looking to S Palm the Rockus needs to be moved to the Choice 3560G switch by installing a
POE power module. Once this is done I can create an internal port (Vlan) that will only talk to the private side.
The Dragonwave and the Rockus Bridge will remain in the public side. • i Ne(i
• Issue q2 was fixed (network loop) was fixed by disconnecting the local management Ethernet cable.
Issue #1 was fixed. 2 PowerOverEthernet (PoE) injectors were installed and both Ruckus were moved to Choice 3560
switch. A cable was installed to interconnect choice switch with LSJ switch to pass vlan 8 (internal Data) and the Ruckus
that was pointing to 5 Palms is now in serviced.
