Tape Libraries

TSM IBM 3584 Library in 613

IBM 3584 IBMLIB0 (613, small, 8 3592 J1A) web gui

User Libraries

IBM 3584 IBMLIB1 (513 s/s, large, 50 TS1120/3592 E05) web gui
IBM 3584 IBMLIB1 web camera (not finally positioned): user is 'demo', no password

The Sun/STK SL8500 libraries do not have a web gui, but the SL Remote Console package gives some remote operation options and of course ACSLS can also be used via sunstk51 for the 513 system and via sunstk62 for the 613 system. The larger of the 2 SL8500 systems in 513 is connected to as stk8500r0 and the smaller as stk8500r1. The SL8500 system in 613 is connected to as stk850060.

Note that presently we can only install the SL Remote Console on the ACSLS Sun hosts: use these to access this facility.

  • Web cameras in the Computer Centre SL8500 robot (logically divided into SL8500_0 ITDC, SL8500_1 user, SL8500_2 test and SL8500_3 ITDC)

    If asked for, the user name is 'demo' and there is NO password. This is a vision and sound system.

  • Web cameras in the bat.613 SL8500 robot (logically divided into SL8600_0 user)

    If asked for, the user name is 'demo' and there is NO password. This is a vision and sound system.

  • Other web cameras in the Computer Centre and Building 613 in server push mode

    These pictures should be almost 'real time'. If they are not, you may need to disable cache temporarily in your web server. In Netscape, select 'Edit' in the tool bar, 'Preferences' and the 'Advanced' option. This should allow you To set 'Proxies' to 'direct connection to the internet'.
