LANs/Routers
Error 404--Not Found |
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:10.4.5 404 Not FoundThe server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent. If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address. |
PoE switches for less
Allied Telesyn last week launched a new lineup of power-over-Ethernet (PoE) and non-PoE switches aimed at small and mid-size companies.
The AT-80000 series of switches includes 16-, 24- and 48-port switches. PoE is available in the 24-port and 48-port devices. The boxes, designed to compete with Cisco's Express 500 switches and HP's ProCurve 2500 series, include 802.1x support for security access on Ethernet ports, VLAN capabilities. For QoS, the switches support 802.1p and Diffserv at Layer 2 and Layer 3, respectively. The AT-8000S/48 costs $1,105, and $2,000 with PoE. The AT-8000S/24 costs $715 and $1,165 with PoE. The AT-8000S/16 costs $575. All switches are available now.
