Subtypes of hubs and switches (and other networking equipment)

Sorting networking equipment is currently a job that we think may be slightly too complicated for adoption volunteers, especially during busy times. Soon, we will have a dedicated area of Advanced Receiving for networking equipment, before we sort it and send it on its way.

There are a few major destinations for networking equipment.

  1. Standard hubs and switches go to Advanced Testing. We are only keeping hubs and switches that are capable of 10/100 speeds. The speed will usually be written on the hub/switch fairly prominently. If it is only capable of 10Base-T, recycle it as Copper Bearing Material. If it is marked as 10/100 or you are not sure of its speed, send it to Advanced Testing to be tested. Hubs and Switches come in various sizes, from four port up to 24 or even 48 port. A pure switch or router is usually distinguished from another piece of networking equipment by the fact that all of its ports are standard RJ-45 size.

  1. CSU/DSU units. CSU/DSU units are Channel Switching/Data Switching Units. They are used for arcane purposes of turning internal phone signal data and voltage types into data and voltage types to be sent over phone lines. Some of these are in demand for enterprise level phone systems, so they should be sent to the White Hole. Almost all CSU/DSU equipment will have "CSU" or "DSU" marked on it.
  2. DSL or Cable Modem/Routers. These items are used for transfering phone or cable signals into signals your computer can use. They usually have a plug for the external communications equipment (ie, a RJ-11 plug for a phone line), and then at least one plug for RJ-45. Right now, we are storing these items in Advanced Receiving.
  3. Cisco Equipment. Cisco manufacters networking equipment from the consumer level up to the enterprise level. All Cisco equipment is currently going to the White Hole.
  4. Print Servers. Print servers are very small hubs that are used to hook a printer up to a network. They usually have at least one RJ-45 port and at least one parallel port. Many of these items are obsolete, but we are sending them to Printerland to make the decision.
  5. Wireless equipment.
