| 43 | | The following information was provided by Bill Seligman, Network Engineer on the particle/nuclear physics half of Nevis: |
| 44 | | |
| 45 | | CUIT manages a router that is physically located in the Nevis particle-physics research building, which is the first red-brick building you see when you enter the Nevis driveway; the "Cyclotron" building is the one behind it, with the big round windows, and that's where the Astro/RARAF groups work. |
| 46 | | |
| 47 | | That CUIT router is in a locked cabinet, and I don't have a key. They take care of the network traffic from the outside world into the Nevis research building. |
| 48 | | |
| 49 | | Four Ethernet cables come out of that cabinet, two for you and two for me. Of each pair, one is a direct link to the microwave dish on top of the research building; that link goes to Lamont-Dougherty across the Hudson River, then down to Columbia. The other is a link to a central network hub in White Plains. Under normal conditions, all the columbia.edu traffic goes through Lamont, and the rest goes through White Plains; however, each link acts as a backup for the other. |
| 50 | | |
| 51 | | Your (the Astro/RARAF) pair of cables connects via a switch to a fiber-optic cable that goes from the research building to the Cyclotron building. That your network link to the outside world. |
| 52 | | |
| 53 | | === Switch === |
| 54 | | |
| 55 | | There is a single switch located on the second floor at the northwest corner of the cyclotron bay. It is a |
| 56 | | |
| 57 | | Linksys Etherfast 10/100 24-port, model no: DSSX24 |
| 58 | | |
| 59 | | with a |
| 60 | | |
| 61 | | 100Base-FX module providing two optical ports |
| 62 | | |
| 63 | | The optical connections come from CUIT and provide connectivity to the rest of the world, as described in the previous section. |

| | 63 | The Astro/RARAF pair of cables connects to a Cisco SG300-10 (10 port) switch (donati.astronevis.columbia.edu). Some of the other ports on that switch are connected to the bay area of the Particle Physics building for the Miller group. And there is a [http://prolineoptions.com/datasheets/MGBSX1-CDW.pdf Proline MGBSX1-CDW] SFP (mini-GBIC) (850 nm) 1000Base-SX fiber transceiver module (equivalent to the Cicso MGBSX1 SFP transceiver module) in that switch that connects to a 62.5/125 µm fiber line from the Particle Physics building to the Cyclotron building. That is the network link to the outside world for the Cyclotron building. The fiber module on the switch has LC connectors while the connector box on the wall for the line to the Cyclotron building has ST connectors. An LC/ST 62.5/125 µm fiber patch cable connects the two. |
| | 64 | |
| | 65 | That line from the Particle Physics building comes into a connector box (with ST connectors) located on the second floor at the northwest corner of the Cyclotron bay. It is connected with an LC/ST 62.5/125 µm fiber patch cable into a |
| | 66 | |
| | 67 | Cicso SG300-28 (28 port) switch (halley.astronevis.columbia.edu) |
| | 68 | |
| | 69 | also with a |
| | 70 | |
| | 71 | Proline MGBSX1-CDW SFP (mini-GBIC) (850 nm) 1000Base-SX fiber transceiver module. |
| | 72 | |
| | 73 | Other connections into that switch go to various other parts of the Cyclotron building. |
