The same thing happened again on January 11, this time Mel Inouye of the 88" restarted the switch for us.
On January 19th, we replaced the switch with the backup switch and haven't had any problem since.
There were no other problems to report.
To activate the dormitory networks, equipment needs to be installed in the HP common area and at each dormitory building. Miranda and Pui Hin also wanted to take the opportunity to clean up the network rack and cabling in the common area, as well as installing a new battery in the UPS. The work at the common area will cause interruption to the wired and wireless HP LAN for up to 5 hours. Pui Hin solicited input from all present for a schedule that will be most convenient to all the observatories. All agreed on March 31st, starting at 7:30 am. If time permits, Pui Hin and Miranda will also install equipment and cabling for the dormitories. Additional time will be scheduled for the following week if needed.
With the capacity of the new equipment, it was decided that Pui Hin and Miranda will take over the management of the wired DHCP network from Subaru. Pui Hin thanked Kiaina Schubert for Subaru's support over the past years.
The option to set up individual VLANs for each observatory was briefly discussed but there was not much interest in such an implementation. More interest was expressed in the deployment of VTP for the extension of observatories' Summit networks to HP. This will allow observatories to preserve private subnets and administrative domains through sites that are geographically separated.
