Preperations for home automation with existing equipment thru network adjustment questions

[Woodsy]

I have several computers on a home network.
ADSL with an Asante FR1004 4 port internet router.(DHCP enabled)
The router has filled up, and I need to use a 4 port switch that I
have to expand for the media server/touch screen kiosk pc and future
expansion in the A/V area of my home. Looking forward to the future,I
hope to have some sort of automation,the kiosk pc just has to many
serial ports for me to ignore.

My biggest question is...
Can I hope to just unplug what is there and re-cable for the addition
of the switch, plug it in and have it run? (ihopeihopeihopeihopeihope)
This is a mixed bag of W2k,NT4S,NT4WS and W98 and has been working
great so far.
Other questions...
Will I have to assign static IPs to the switch connected pcs?

Will I have to use a crossover cable for the connection between the
Asante and the D-Link DSS-5+(vH3)?
Never mind, found it in the manual,answer is no to the crossover
cable.

Is there a problem with 50' between the devices?

This is sundays project, with the normal massive clean of the wall
space and inside the equipment. Nothing says it has to be done then,
just a personal goal.(get up sunday and power down all equipment)

Back Shortly, going to town for a handfull of cables.

DHCP will handle all PC up to the 255 maximum number on the 192.168.0.0
subnet. Each hub will need to copnnect with a crossover cable to the
router hub ports unless the router or hub have autosensing
capabilities. Ethernet is allowed 100 meters (around 388 feet) from the
hub to PC

328 feet not 388

You may need to assign IP static adresses to your internal
computers if they will be running servers that will be accessed
from other computers. Changing IP addresses tend to break these
types of setups.

That's true only if the DHCP leases expire and are handed out to other
devices. When offered an address a device will generally get to keep that
address 'for the duration' unless something else gets assigned it. This
usually only happens when the DHCP pool of leases is very small and the
devices nearly consume all of it. That and the expired machine was off long
enough for the server to 'think' it could reassign the address. Now, this
is usually the case for most home and small office level router devices that
have DHCP services. ISP connections using DHCP are often another matter as
are larger office networks. They usually have policies that would explain
what's what.

That said, for devices that have server-like functions it's often a very
good idea to give them static addresses. Just assign them address from one
part of the subnet and start the DHCP address block somewhere else.

As for 'will it work' most switches will automatically figure out what sort
of cable is required. That said it's always good idea to have a spare
cross-over cable handy. DHCP should, if the devices are truly switches,
work seamlessly across them.

My home computers have assigned IP adresses so when there is a
power blip and they and the router reboot, the assignments all
stay the same. Some routers won't do port fowarding when DHCP is
enabled. I've got a laptop that uses DHCP and it gets its address
starting at the .100 point I've set for DHCP in the router.

Thank you for this informative post, sounds like it will work, as the
current system works across reboots and shutdowns for maint.
I just was not sure if the DHCP would still apply thru the switch.
Logic flaw on my end, what you posted made sense of it for me.
Theory in hand, here comes the other hand for the power switch!

Thanks again,and to all the posters here!
