looks good, i wouldn't have used that psu tho, there is no shielding, and SMPS's put off alot of RF.. and switching noise..

Packet Tracer network I started building to do my final review of ICND2 topics. Simulating an Enterprise network with internal/external services and a few branch sites. Should allow me to cover the ICND2 exam topics pretty thoroughly.
 
IBM serial gear at a major bank:

kPZf0.jpg


Was still plugged in. No serial terminals in sight. There's a Cisco in there somewhere. "Rack" = old filing cabinet.
 
The number of places I`ve gone in with random bits of kit no longer in use and beeping away is daft. I report them and the next time I go there they`re still beeping.

UPS`s with dead batteries
UPS`s with the output sockets looped back to each other
UPS`s with the output sockets looped back to each other and fed off the same PDU they are feeding.
And one I`m particularly impressed (in a bad way) by...

A server with dual PSU`s, one PSU fed directly off the mains, the other PSU plugged into the output of a UPS that wasn`t plugged in or switched on.

Server LCD display lit orange and scrolling PSU failure messages....

This one was a law firm I do some stuff for from time to time, this was the first time I`d been in their new office since they`d moved.

Apparently, they`d paid a company to do the move properly!

Amazing!

Backup? Whats a backup?

Indeed they are, they do have daily backups though, they had the corresponding days tape in the tape drive when I was there, although that won`t be much use if there`s a power failure...:rolleyes:

My 4yr old is sitting here watching me and when I came to this picture he asked me why there were wires everywhere, lots of wires. :p

Looks like you have a spanning tree problem ... My guess is the Software Dev switch is your spanning tree root.

Yeah, something I need to fix :(


When I took this screenshot I had just setup PAT/NAT, Frame Relay and VTP, gonna fix up the LAN today!
 
Re-cabled a mess today. Lets not get into a velcro vs zip ties fight here this is all permanent cabling that has not moved in 2 years. Notice how the 4 switches at the bottom were not even mounted! They sat there for 2 years like that. The Cisco switches have open ports for a reason. I know the gaps are between switches are not 1u but I was not going to un-rack everything and redo it, plus the rackmount ears for those 24 port switches are not the right length they are too long.

velcro is more for places where cables will be added/removed on a pretty regular basis, I use zip ties for straight telecom closets, like ones just running up phones to offices- typically they are in place with as many phones as will be added or what will be added in the future is very minor and can be cable managed seperately.

Good work, one time I saw 4x 42U racks that were literally covered in hundreds of cables, then buried below all of that there were about 10 switches. Luckily I wasn't responsible for or in charge of that mess.

True, since i need to replace the fans. Might just as well make a little L-shaped RF/EMI shield from 1mm steel for the psu that will also hold 2x 40x40x20mm cpu fans.
 
Meet the TANK

Australian 19 Inch Class "C" Secure Half Height Rack
Ex Australian Department of Defence

Not your normal run of the mill half height rack, this baby is build TUFF....so Tuff that even having fallen off of the back of a truck (yes literally) this baby is only bruised not beaten.... with a slighty tight to open door and a sticky lock.

Which was fixed with a sledge hammer...(seriously):D

Check out the locks on the Doors... (which by the way are seriously heavy in themselves)..
None of this fairy flimsy push to open rack locks
This baby has solid steel latch, with top and bottom protruding rods to lock it closed.

To keep noise down a little I fitted it with some noise reduction foam (doors, top, bottom and sides)

Vented in the top and bottom
With two rows of tack welded and removable access holes of differing sizes along the top and bottom.
Along with removable (bolted) access hole sections along three of the four lower sides. (two each side)

Anyways I have changed my setup in my garage to a different rack, so the TANK is now up for sale sadly....if I had the room I would keep him.... and No I don't think you want to ask a shipping cost from Australia for him

Thought I would show some photo's of him after I emptied all my servers out and before he departs to another home.

Enjoy

It seems remarkable that someone would worry about physical security so much more than network or logical security.

Without physical security, network and logical security dont matter.

If i get physical access, im going to break in no matter what. Its not about stealth at that point.

Get a 4U hanging wall rack, I'm fairly certain that you can get 1, 2 or 3U as well.



Ours has a Tripp-Lite battery and a 2520 ProCurve PoE switch.

all that stuff can be put into this on the side wall where all his cable is coming down and POOF would looks WAY nicer no long loops etc etc. AND the bracket is like 30$ so it's not expensive..

We originally had a 3550 PoE switch, was deep as hell, would not fit on one of those. Though I did have one of those that we gave away recently. The UPS still would not fit in it though.
 
Some updates to my PT Network, fixed the STP issues in the MH LAN. Also fully configured NAT and PAT. All internal rfc 1918 address are translated to a signal global address using overloading. Also some ports are forwarded for services like http,https, smtp, pop3 and dns. Configured a few ACL's to protect development traffic internally. The ISP1 site is operational and providing DNS and HTTP services to users via NAT port forwarding also. Still some work to do but I have covered about 50% of the ICND2 topics so far. I may go for the cert next week!
