In addition to traditional Sun server and workstations, we have a dozen terminals known as Sun Ray 1 (with 21" monitors).
They are managed by a Sun Ray server (currently named FIRE) over a private network. These terminals are similar to X terminals, in that they have no CPU, but run desktop sessions from remote workstations on the (public) local network, effectively putting a virtual workstation (minus its removable media or peripherals) on your desk.
When a Sun Ray terminal first comes up (e.g. when their server is rebooted), you get a login window for FIRE (the server). However, you cannot login on FIRE because regular users do not have an account on the server.
Instead, you have to click on the Options menu and select Remote Login. You can then choose either Enter Host Name... or Choose Host from List... Do not choose SunRay, as this is FIRE's name on the private network (so the same restriction as above applies).
In either case, the host you choose should be determined as follows.
It is sometimes necessary to reset the Sun Ray server's X Windows server in order to clear display problems on individual Sun Ray terminals. This may cause active sessions to be terminated on other terminals as well, so you could find yourself suddenly logged out even though everything seemed to be going fine for you. Keep that in mind if you typically remain logged in to a Sun Ray terminal ``after hours''...
Below is a (mostly technical) table of our Sun Rays, intended primarily for management purposes.
