For those of you who are running Cisco 6500 series chassis, and are looking for upgrades it can be quite confusing. While it’s been out awhile, the Supervisor 2T is one possible upgrade.
The Cisco Supervisor Engine 2T is supported only in the Cisco Catalyst 6500 E-Series chassis:
Somethings to keep in mind. They must have generation 4 line cards. LineCards will CFC’s will work, as these are newer. Modules with DFC 3 will not power up.
Linecards which are compatible:
• WS-X6908-10G-2T, WS-X6908-10G-2TXL
WS-X6704-10GE with CFC
WS-X6724-SFP with CFC
WS-X6748-SFP with CFC
WS-X6748-GE-TX with CFC
WS-X6148A-RJ-45, WS-X6148A-45AF, WS-X6148-FE-SFP, WS-X6148A-GE-TX, WS-X6148A-GE-45AF, WS-X6148E-GE-45AT
With a DFC4 or DFC4XL upgrade (WS-F6k-DFC4-A, WS-F6k-DFC4-AXL)
With a DFC4 or DFC4XL upgrade (WS-F6k-DFC4-E, WS-F6k-DFC4-EXL)
This is just sitting idle.
As more and more Wireless ISPs (WISPS) get into licensed microwaves, bigger antennas, and fiber up the tower (FUTT) they are getting into an arena typically reserved just for the Cellular and broadcast folks. This can result in an overwhelming amount of things to deal with.
If you are renting space on a commercial tower managed by a regional or national company such as American Tower (ATC) you will run into things like application fees, engineering studies, and closeout documents to just name a few. Once you have your notice to proceed (NTP), the real work begins.
During your negotiation phase, and in your contract, you should have a center line on the tower. This states the center line on the tower where your equipment is mounted. An example is if your centerline states 200, on most contracts that means you have something like 5 feet above that and 5 feet below that. Think of it as a window. You have a window of 195-205′ on the tower for your equipment to fit in.
The equipment you put on the tower was specified in the engineering phase of the paperwork. Model numbers of mounts, antenna models, and all that are decided before the first piece of equipment is ever put on the tower. This is very important to adhere to because many tower companies will require a closeout procedure. This normally includes pictures of your equipment and how it’s mounted, pictures of what is called a tape drop, and other things.
The sheer amount of things to think about on a commercial tower with multiple tenants could extend this blog post on for a long time. But, one of the biggest things to consider is when you are installing how your cable runs, antennas, etc. are in relationship to other equipment. Are your cables somewhere they might be stepped on by someone passing your equipment to get to theirs? Does your equipment cross mounts which may be removed later or modified?
In the second part of this series we will talk about some of the higher-end tools which may save you tons of time, thus paying for themselves rather quickly.
When setting up a device, especially a network router, you often have the option to leave things “default”. What does this really mean and what effect does it have on your network?
What you are basically saying when you leave something as default is “let the router determine what to do”.
This can be a problem when the default behavior changes. This is most often changed when going from one software version to another. Maybe someone determined that leaving a particular option enabled was no ideal. Maybe it caused issues, or is now being replaced by a different way of doing things.
Sometimes default configs are designed to make the product easier to configure. This is typically true of many consumer based devices. The company wants you to have a good experience and not have to call them for technical support.
Keep these things in mind when you see a checkbox or something that says “default”.

Ligowave has recently launched a small form factor 802.11N radio. This is one of the growing number of devices designed for the SOHO and small and medium enterprise installs. You can read the full data sheet here. https://www.ligowave.com/public/downloads/APC%20button.pdf
One of the first things I do with a unit like this is login and look at the existing firmware. My unit came with Version 5.95 and the latest available was 7.02. Since this is a new platform for me, I can’t speak to the in the firmware, other than what I saw on the surface.
I noticed some cool things about this unit, which some other vendors are lacking at the moment
The spectrum analyzer under tools loaded very quickly. No complicated Java or slow load times. The following is a screenshot from it sitting on my desk.
Just like the spectrum scan the site survey was quick and trouble-free. It picked up everything I expected it to see. It is very handy to just pop into a unit and see what it sees.
SNMP and SMTP traps
Something that is very handy for the small office or small deployment was under services…System alerts. You can have the device send an e-mail or SNMP trap based upon some things most folks would really like to know about. For example, if the noise floor gets greater than a certain DB it will let you know. Pretty cool
These have a street price in the $40-50 range. This has just been a quick overlook. I hope to get into some real world uses of these in the near future for a followup to this.
