On July 12th, CFHT and Gemini became the first participants of the ATM network, followed by SMA on the next day.
CFHT encountered some problems during the upgrade which is noted here for everyone's benefit. IOS version 12.0 requires at least 64 mbytes of memory. After activating the ATM connection to the MKOCN summit switch, a lost in bandwidth was observed on the DS3 between CFHT's summit and Waimea routers. HawTel maintenance suspects the problem to be related to IOS version 11.1.
A strange interaction has been observed between the Cisco and Proteon FDDI interface. The FDDI interface of the summit Cisco 7206 router shuts itself down everytime the 88" CNX500 router (its FDDI neighbor) is rebooted. The 88" CNX500 router and FDDI card have been replaced.
Pui Hin reported that three CNX500s had to be replaced in the past three months. So it seems like it is a good time to get rid of this old equipment.
Note:
-
The problem with the interaction between the Proteon
and Cisco FDDI interface has re-surfaced. Pui Hin is
currently working with Cisco on this.
- CSO - July, 2000
- CFHT - done
- Gemini - done
- IRTF - before the end of the year
- JAC - equipment on order
- Keck - equipment on order
- SMA - done
- Subaru - before the end of the year
- UH 88" - before the end of the year
- A DS3 between UH Manoa and the Hilo University Park will be procured.
- A second DS3 will be procured to connect Hilo and the Summit. The current T1 frame relay will be kept as a backup.
- Benefits of the two new DS3s will be available to all MKOCN members no extra charge.
- Gemini will pay to have the landing point moved back to the summit if there is not enough interest to support the second DS3 after the two years grant period.
- Gemini will preempt 10 mbps of the bandwidth between UH-Manoa and Hilo
- New equipment to establish the new Hilo landing point
includes:
- two Cisco 1010 switches, one active, one spare
- one Cisco 7206VXR router (A Cisco 7206 currently installed at the summit will become available as a backup once everyone has migrated to ATM)
- two Catalyst 2924 Ethernet switches, one active, one spare
- Equipment and DS3s will first go into the Gemini building and will be moved to the new IfA building when practicable.
- A Hilo based part-time technical support person will be hired.
Funding after the grant period is not certain at this point. Some cost sharing arrangement might need to be worked out among the observatories.

Note:
-
Due to the delay in the availability of the two DS3s, plans have
been revised to install DS3s and equipment directly in the
new IfA building.
