The new stuff chronicles #1

The TEFAF is long gone and still it’s been nearly a month since my last post. Anyway, I have made a decision: from this day forward I shall name the posts that are about new stuff I got “The new stuff chronicles #x” and today is #1.

The new stuff chronicles will be a new series of posts here on Pingwing.us purely and only for new stuff I receive as gifts or which I buy or otherwise aquire. Today I have some new things I got through second hand internet trading and something I got from a classmate a whole while ago, but I haven’t told the world about that yet and something I got for free from another classmate, also a whole while ago…

So what is the stuff that’s going to be shown is this post:

  1. 2x Nortel Networks Baystack 450 24T Ethernet Switch
  2. 1x DAP Audio DJ-Station
  3. 1x HP Laserjet 3150 multi functional printer

Let’s start with the switches

Baystack 450 24T

Baystack 450 24TThe Baystack 450 24T is a 24 port fast ethernet switch which is fully managable. Fast ethernet means that it supports up to 100mbit/s rather than only 10mbit/s like the Baystack 310 24T or the Cisco Catalyst 1924E which is displayed on this page.

Amoungst the things that this switch supports are VLAN, multi link trunking, spanning tree protocol and management through Telnet. There are ofcourse a lot more things supported by this switch, but those are probably the most notable.

Another interesting feature is the possibility to upgrade the switch with a cascade module in the back to enable 2.4gbit/s connections between up to 8 Baystack 450 switches. The cascade module connects the switches directly on their backplanes and more or less makes them function as one big switch and the best thing about that is that the cables required for this feature are standard SCSI cables which are relatively easy to find.

The only real downside of these switches is that they don’t have a built in uplink port. Allthough an uplink port of nothing more than a cross linked ethernet port, mostly the uplink port is faster and a 1000mbit/s uplink port would have been very nice. But an uplink port can be added with a fiber optic uplink module, but I have no use to fiber optics whatsoever.

And here is a picture of all my Cisco Systems routers and the switch and my three Baystack switches stacked on top of eachother:

DAP Audio DJ-Station

DAP Audio DJ-StationThis is my mixer panel. Now you might ask what the use of a mixer panel is for home use, but I can tell you that the sound quality is much better with this thing connected between my computer and my speakers than with the speakers directly connected to the computer. And added to that I also experiment with audio (mainly vocals) on my computer and the recording quality of the microphone is also a lot better through the mixer than directly into the computer.

The DAP Audio DJ-Station has 8 stereo channels of which 4 can be used simultainiously. Which ones to use can be chosen with the little switches above each volume slider. It also has two seperate microphone input channels than are used independantly of the other channels. It has 3 stereo outputs on the back and an extra on on the front. The one on the front is the cue output, which is normally used to listen to a song by a DJ before actually playing it on the main output. It also has a main output which is a 2 channel stereo output, a booth output, which is pretty much the same but has it’s own volume knob and is meant speakers that the DJ himself listens too instead of the main speakers and it has a record output, which I connected back to my computer’s line-in.

Besides that it features some pretty useless but funny sounding soundeffects and echo and reverb for both the main/booth/cue output and for the microphone input.

HP Laserjet 3150

HP Laserjet 3150I got this cute little printer from a classmate who had upgraded his system with Windows Vista and this old bugger didn’t work with that anyway, so he got himself a new one and this one was standing in the way.

In Windows XP I still can’t use all of it’s features, but the main feature, printing, works just fine.

This thing is actually a fax machine as well as a printer, scanner and copier. To use it as a fax machine I would need to connect it to an analog telephone line, but I have no use for that feature and I haven’t tested the copier function as of yet and the scanner function doesn’t work on Windows XP. You’ll need Windows 9x/NT 4.0 for that feature. A shame really, but it just scans grayscale anyway, so it’s not that usefull.

Nortel Networks Baystack 310-24T

And another two weeks have passed *sigh*. So many things to post, yet I barely ever get to actually posting it… Anyway, right now I have material to post about one thing and it’s even the most recent thing… Why not post the older stuff first? The answer to that question is simple, I don’t have all the material I need for the other things.
Baystack 310-24T
So today’s topic is a switch. A pretty big one too. A Nortel Networks Baystack 310-24T. Nortel Networks isn’t very well known in this part of the world which is probably also the reason why I had never heard of it before I visited my girlfriend over at her parent’s house for the first time. Her brother has quite a few Nortel switches and two of them were simply in the way and he no longer wanted to use them because they were too old. Both of these switches were Baystack 310-24T models and he simply gave them away together with his dad and I was the lucky one to receive both of them.

The Baystack 310-24T switch:
Baystack 310-24T
The Baystack 310-24T switch has 24 10base-T RJ45 ethernet ports. This means that it has a maximum transfer speed of 10 megabits per second on each port at half duplex. Half duplex means that it can only send or receive at a port at one given time. It is not possible to send and receive on one port at the same time. Besides that it has one 100Base-TX uplink port which means that it has one port with a maximum transfer speed of 100 megabits per second at full duplex. So it can send and receive at the same time. And uplink means that it’s supposed to be used to connect it to another switch. The pins in an uplink port are arranger differently, crossed over so you can use a standard straight through UTP cable to connect it to another switch, in most cases the other switch would be a faster backbone switch to which it will be connected to one of it’s normal network ports.

Whenever I get the time I’m going to figure out all of it’s specifications and dedicate a page to it and maybe I’m going to try to get some more Nortel Networks equipment as well, because there is always more than just Cisco Systems.

I’ve been using the combination of a cheap Sweex broadband router with an old Kobishi accesspoint to provide myself with a wireless internet connection, but the age of the equipment was starting to show. The accesspoint would not pass through DHCP (Dynamic Host Configuration Protocol) and it failed to provide service a lot lately requiring me to reset and completely reconfigure the old thing about every 2 weeks. Sometimes it lasted longer, but sometimes I had to reconfigure it even multiple times per week.
The Sweex broadband router on the other hand is still functioning perfectly, but I didn’t want to just get a new accesspoint, this time I wanted it to be all in one.
