In addition to the 1 Gb link through Waimea -- as part of the effort to extend the SX TransPORT to MK -- UH-ITS is working with Hawaiian Telcom on a plan of paying an up-front amount of money now in order to reduce the future cost of the connection between the Summit and Hilo, and between the Summit and Waimea.
However, there is now some urgency in putting the Summit Gigabit switched network in place. Some of the Cisco 7200 series of routers -- mostly what is installed at the observatories -- will reach "End of Support" by Cisco in December. For the Summit, Pui Hin suggested the Cisco 3560 switches for an inexpensive replacement of the Cisco 7200 series routers at the observatories. The current plan is to replace the 7206 VXR at the Summit Communication room with a Cisco 3750. Since we don't have any plans to deploy OSPF among the observatories on the Summit, the observatories may choose to purchase their 3560 switch with the Standard software image. It will be possible to buy the enhanced IP service software module at a later time.
