|Determine what kind of Network Device it is ||
 +
;There are several kinds of network devices.
 +
* Hubs
 +
** A hub is a device that provides multiple ethernet ports for plugging in multiple wired devices into a network.  From a technical standpoint, hubs are fairly simple: they take information that is received over one port and sends it back out over all the other ports. In order to work properly, a hub typically requires the existence of a device that manages and directs traffic somewhere on the network it is plugged into in order to work properly.
 +
* Switches
 +
** A switch is essentially a hub that can better handle more information passing through it.  Like a hub, a switch needs a device that manages traffic on a network in order to work properly.
 +
* Routers
 +
** A router is a small computer, typically with a built-in network switch, that manages and directs traffic.  A router can assign IP addresses to computers, pass their requests for information from computers to a gateway, and redirect incoming information from a gateway to a specific computer.  A router itself is typically the central component of a home network.
 +
* Gateways
 +
** A gateway is a device that allows you to connect networking devices to the Internet.  Gateways typically only allow one connection for a network device, but newer ones have built-in routers and switches.  Some may also create wireless networks.  A cable or DSL Modem is a type of gateway.

Welcome to Network Testing. This is an area in [[Advanced Testing]]
 
 
Network Testing works more-or-less like this:
 
 
# Incoming. Everything comes in, unsorted, and goes on the bottom shelf of the rack.
 
# Sorting. We look at [[Network Switch Testing]] to find out what is instantly recyclable and create a recyclables box somewhere if we don't want it. Otherwise, if it's something we want, find the AC adapter for it. If we can't it gets recycled. If we can, pair it with its AC adapter, put it in a bag and put it on the Sorted shelves (2).
 
# We test sorted devices from the Sorted shelf and if they're good, we write up a "Tested OK" sticker, stick it to the device, include the AC adapter, and put it in the Store box (3).
 
# Big weird devices go on the Other shelf (4).
 
 
The network device testing station currently consists of a computer with a nic that can handle gigabit Ethernet and wireless g. This computer also has a serial port and software that can talk thought it.
 
 
==Testing kit (yellow tub)==
 
 
The yellow tub contains three things that might come in handy for you. Please keep it assembled and free of other things:
 
 
# An ethernet cable (green).
 
# A crossover ethernet cable (red).
 
# A generic power cable (black).
 
# A paperclip.
 
 
==AC Adapters==
 
 
* The ~5V and ~12V adapters are in the red trays.
 
* The ~6V and ~7V adapters are in crates below the table.
 
* Belkin, D-Link and Linksys branded adapters each have their own crate below the table.
 
* Extra 12V, 1.2A adapters we save in a crate below the table to go to the Store.
 
* When all the crates are full, we recycle the excess in the yellow tub to the left of the table.
 
 
==Testing a switch ==
 
# Verify that the network device is not to be immediately recycled, by consulting the list below
 
# Connect power to the switch, and verify it starts up (some advanced switches may take up to a minute to start up)
 
# look for a reset button and if there is one reset it.
 
# Connect the network cable that has the internet on it to the wan or uplink port.
 
# Verify that the link lights illuminate on the switch for the appropriate ports.
 
# Plug in the network cable from the computer to the router.
 
# On the PC surf the internet. this should not feel slow.
 
# Do this on every port by moving the network cable that connects to the computer
 
# check the wifi by connecting to it and serf the net
 
# If the network device has a way to login, try to.
 
# If it works, label it, "Tested OK"
 
 
==Testing a Wireless Router==
 
 
 
# Grab a machine from the "2. Sorted" shelf on the right. It will hopefully be in a plastic bag with an AC adapter. Make sure it is a wireless router.
 
# If you need an AC adapter, there are some sorted by brand under the desk, and some by voltage there and in the red bins.
 
# If you need an antennae, there are some in a bin on the desk.
 
# Power the router up.
 
# Reset it. This usually involves turning the machine on and sticking a paperclip in the reset hold on the back and holding it there for ten seconds.
 
# Plug an ethernet cable into one of the back ports. Any one except the one labeled "WAN" will do. Plug the other one into the NIC on a computer you can use to test it.
 
# At this point I unplug the router, pause, then plug it back in for good measure.
 
# Open a terminal and use this command: "sudo dhclient [Enter]". The password is "freegeek", This command looks for the router and assigns an ip address to the system.
 
# In the dhclient output you will see the ip address of the router under "DHCPNAK from [ip address]". Remember this number.
 
# Open up a web browser and type that ip address that you got from your dhclient output into the address bar and hit Enter.
 
# The router might ask you for a login and password. If you reset the router properly it will be a default login and password that you can find on the web by googling the model number and "login". Or something like that.
 
# Make sure you can login. If you can't make it this far ask for help or recycle it in the yellow bin the the left.
 
# Plug it into an ethernet cable that is connected to the internet.
 
# See if you can connect to it with the left computer (it has a wireless card).
 
# If it works, put a sticker on the device noting the ip address that you need to configure it, including the login and pass. Also include the default network name (usually the brand name, you can find this in the configuration page, above).
 
 
== Recycle Criteria ==
 
;Devices to be recycled without testing
 
* DSL and cable modems (and DSL filters, phone cables, etc, if the store already has a few)
 
* DSL and cable modems with built in hub, 'internet router', or wireless
 
* 10BaseT hubs
 
* Cheap-looking little no-name-brand hubs if they are piling up at the testing station
 
* Cheap-looking little no-name-brand hubs if a matching power adapter can't be quickly found
 
* Devices with noisy or bad fans, or that appear physically damaged
 
 
;Devices to leave for advanced testing
 
* Consumer-grade internet routers (with WAN ethernet port, not with DSL or Cable ports)
 
* Consumer-grade wireless access points and wireless routers
 
* Managed 10/100 switches with a console port that do not seem to pass testing
 
* Professional-looking rack mount routers, firewalls, and other network devices
 
 
==Preparing the device for the store==
 
# Plug its AC adapter into the device and make sure they won't be separated. (Maybe use a rubber band)
 
# Put it it the clear plastic Store bin on the shelves.

STEPS NOTES AND DETAILED INSTRUCTIONS
Determine what kind of Network Device it is
There are several kinds of network devices.
  • Hubs
    • A hub is a device that provides multiple ethernet ports for plugging in multiple wired devices into a network. From a technical standpoint, hubs are fairly simple: they take information that is received over one port and sends it back out over all the other ports. In order to work properly, a hub typically requires the existence of a device that manages and directs traffic somewhere on the network it is plugged into in order to work properly.
  • Switches
    • A switch is essentially a hub that can better handle more information passing through it. Like a hub, a switch needs a device that manages traffic on a network in order to work properly.

    • A router is a small computer, typically with a built-in network switch, that manages and directs traffic. A router can assign IP addresses to computers, pass their requests for information from computers to a gateway, and redirect incoming information from a gateway to a specific computer. A router itself is typically the central component of a home network.

    • A gateway is a device that allows you to connect networking devices to the Internet. Gateways typically only allow one connection for a network device, but newer ones have built-in routers and switches. Some may also create wireless networks. A cable or DSL Modem is a type of gateway.
Determine if the Thrift Store wants it
Check the Whiteboard.
  • In an open Firefox browser, click where the toolbar says "Whiteboard." You can also find it here: Whiteboard. This will tell you what the store does and does not want on that day. Recycle anything that they do not want.
Things we don't test
  • Firewall/VPN devices
Recycle anything not needed by the store, and any of the above items which we do not test.
Pair the Network Device with Power Supply

Somewhere on the device it should give the required voltage and amperage. Once you find a matching power supply that fits, plug in the power supply and place both the device and power supply into the blue bin for network devices to be tested.

Check for Damage

If it's missing parts or visibly broken, recycle it. If there's dirt or grime wipe it down with a rag and some cleaning solution.

Check for Power On

Grab a networking device and its attached power supply from the blue tub. Plug the device into a power source.

  • If there are power lights, make sure they come on.
  • If there is a reset button, press it for ~30 seconds to restore default settings.
Test Networking
  • Connect the blue Ethernet cable attached to the computer to one port and the gray Ethernet cable labeled Das Unternet (yellow tag) into another port on the switch.
  • Open FireFox and click the Drydock icon on the far left of the bookmarks bar at the top. If the connection is good, you will see a page that says It Works! You might need to disable wireless connect for the test to work(Uncheck Enable Wireless).
  • Test the remaining ports the same way. Make sure to do this systematically so you know all ports have been tested at the end.
  • If the one or two highest-numbered Ethernet ports don't work, they're most likely designed to be used to connect to another device in the network.
If it is a wireless router
Final Preparation
  • Affix a "Tested By" sticker with your initials on the device.
  • Place in the "Store" box.
  • If it is the last device you're testing for the day, please clean up the testing station, putting away tools, cables and everything else.
