Rats Nest Part III – Done – Network Upgrade Complete.

Thursday, February 18th, 2010

All done, I need to configure both switches, but all the manual work is complete, old 3COM switches removed, new HP switches installed, and all the network patch cables patched in again.

I’ll just have to wait until Monday morning for the issues to be reported! I predict a busy day Monday!

Rats Nest Part II

Tuesday, February 16th, 2010

Spent most of the day un-taggling network cables…but I can now see the light at the end of this very long tunnel.

In case you were wondering the old switches have been divided into two distinct areas, because they are two different physical networks, that will be VLAN-ed on thje new switches. The new switches are installed, and configured, all the VLANs tagged and untagged, so all I have to do tomorrow, is to hopefully connect all the cables back!

Rats Nest

Tuesday, February 16th, 2010

One of my projects on a client site, is to replace all the defunct, old 3COM network equipment with a new core HP Switch. This network communications cabinet currently  has seven (7) old 3COM switches (3300, 3300XM, 3000SM) all requring power, the communications cupboard gets very hot with all this old network switch equipment, and there is no more room for additional networking. So it’s being replaced with an HP core switch. It’s a very tedious job, labelling all the cables pulling them all out, removing all the older networking equipment, and re-installing the new switch, and cabling up again. But it’s a job that needs to be done…

So whilst your reading this today, give a thought for me, in a dusty, dark cabinet, with a rats nest of cables…..

In the long term, the advantages are clear, lower power consumption, less heat, electricity, CO2, and more network connections for more computers!

Goodbye Mr 3COM!

Monday, December 21st, 2009

I’ve been using 3COM networking kit for at least 20+ years, it was a real shame that 3COM in 2000, exited the high-end enterprise markets, concentrating on the SOHO market, 3COM switches were never the same again.

I’ve now decided to replace all my 3COM networking equipment with HP Procurve kit, and shortly after doing this, Hewlett-Packard announced, it will be acquiring 3Com for $2.7 billion in cash! So maybe 3COM technology will appear in HP kit in the future.

I’m dumping all my 3COM Switch 3000/3300/1100/1000 switches for HP Procurve 1810G-24 fan less, lower power switches. I’m still keeping the Intel Gigabit Fibre switches for the moment, because the servers all use gigabit fibre connections, so I’ll connect the fibre to mini-Gbics (SFP – small formfactor pluggable) in the Procurve switches.
