2017-07-14: Problems getting to TempStorage4?

Although most of our users have transitioned to TempStorage4 successfully (see FastFacts/Network for instructions), some are still having issues.


Try to use a different computer to access TempStorage4. Factors that might matter are:

  1. Network type: WiFi (NOT GuestNet!) vs Wired Ethernet (preferred)
  2. Operating system: Windows vs Mac, which version (NOT WinXP!)?
  3. Computer: Clinical/Enterprise-managed computer vs lab/self-managed computer
  4. Network location (e.g. Public Health, Hospital, and Basic Sciences are all managed as separate networks)
  5. VPN access: typically used from outside Hopkins, but can be done from inside Hopkins; for additional information, see (you'll need JHED authentication)

When troubleshooting with a different computer, try to vary one or more of the factors listed.

Asking for help:
Please email us the results of your attempts at troubleshooting, the answers to the factors listed above, and whether your computer(s) have previously been able to reach TempStorage3. Although computer communications can cross many 'jurisdictions' (see [d] above), we will do what we can to help.

2018-01-17 (Leo FESEM): Leo FESEM: Not available until further notice

The Leo FESEM is not available due to chiller issues. As a result, we had to shut the microscope down. We will keep everyone updated and let you know as soon as we have the microscope back up and running.

2018-01-12 (Zeiss LSM 780 FCS): Zeiss LSM780, 561 laser replaced

2018-01-05 (Leo FESEM,Philips CM120 TEM): Chiller swap: LEO offline, Philips working again.

This afternoon, we swapped the chiller for the LEO FESEM with the chiller for the Philips CM120, which is broken. Hence, the Philips is now operational, but the LEO is now offline.

Until the chiller gets repaired/replaced (waiting for technician visits), we plan to time-share the chiller between the LEO and other instruments.

Sorry for the inconvenience.

2018-01-02 (Philips CM120 TEM): Chiller broken

Fri 1/5/18 Update: We swapped the chiller from the LEO SEM to the Philips CM120 so that the Philips is now functional and the LEO offline. The broken chiller was examined by JHU Facilities, but they can't fix it. A contractor will come next week to see what they can do.

Wed 1/2/18: The chiller for the Philips has stopped working. Both the water pump and the condenser are not running, despite being powered. We're waiting for JHU Facilities to examine the equipment and provide their assessment.
