I've been searching for cable management strategies for server racks,
and can't seem to find any specific guidelines.  I presently have a
four-post server rack with several servers, a 48-port switch, and a 48
port patch panel.

I want to purchase a used instrument for testing the quality of Cat5e and
Cat6 cabling along with distance measurement to any shorts or open circuits.
Which model should I look for, what gives me most functionality and quality
for the bucks.  I'm thinking of around USD 500-1000 on ...

Does it exist devices with several ethernet input LAN sockets and one output
socket which enables me to select by software commands which input port to
connect to the output?  (Some kind of KVM switch but for ethernet).
At least 100 Mbps (CAT5 cable) compatible.

Does anybody know what had happened to this very helpful and informative
website?
It looks like they are gone, or what?
Please share your awareness with me if you know something. Maybe there is an

Can a single Cat5e cable be used for both computer networking and for a
telephone line? I ask because I read somewhere that for computer
networking "only pair 2 and pair 3 are actually used, and pair 1 and
pair 4 are free". Our office network consists of three computers. Two

Re: the thread with the patch panel woes.  I was asked to fix an open at
the patch panel jack.  It shows open at the patch panel with my
DSP-2000, so i'm going to have to repunch it down.  But I've never had

I have Cat 5 and Coaxial cabling installed in my house.
I want to feed (a) an audio signal, (b) video signal, from a wirelessly
controlled sub-floor PC to wall connections.
So, I anticipate using 4 of the Cat 5 wires to feed an audio signal to hifi

We are going to be routing 12 metallic-sheathed fiber optic cables
across our plant floor (usual mix of 480V, welding, etc) and into the
datacomm room.  It seems to me that the metallic sheath should be
grounded at the point where the cables enter the room, to drain off any

Reading the signature lines in some of the recent postings, I found the
following links from two of the contributors to be quite helpful in
providing free information about networking and cabling:

Long story..short version.  Just before I started with my current
employer, they moved office locations.  They hired a local contractor
to install the electrical and low voltage cabling (voice and data).
When I saw the patch panel terminations, I got nervous.  Each cable in

I wonder if anyone can help me understand something. I've just read the
whitepaper about the VCT Technology by Marvell and the TDR technique used.
I was just wondering, how did they implemented TDR in software? Did they
manufacture the NIC in such a way that it acts as a ...

We have a PentaScanner+ that we've lost the calibration cable for. This
is the one with the 36pin centronics connector at both ends.
Would anyone have one they'd like to sell cheap or could someone supply
me with the cable pinouts?

Hiya,
I am a technical manager at a company that offers serviced office space.
We have our own PABX and network systems and the building is flood-wired
with CAT5 terminated with female RJ45 wall sockets (pretty common).  I
