Hardware changes/upgrades at KC

10 September 2001

A 100mbit Fibre to the Auckland Peering Exchange (APE) was commissioned this week. This will provide local (NZ) connectivity to other internet sites using the APE, initial peering will be with Ihug and Asia Online. This link replaces the 10Mbit fibre installed from Clear in June this year.

8 July 2001

The second Cisco 7507 router has been fully commissioned at KC's main offices in Queen Street, Auckland. The ATM circuit from Clear was moved to this router leavingthe first 7507 to connect to the Telecom ATM circuit and several channelised wideband DDS circuits from Telecom.

1 June 2001

A 10Mbit fibre link to Clear Communications was installed today for local(NZ) internet connectivity. This connects to the Auckland Peering Excahnge (APE). This link is in addition to a 2Meg and 4Meg links to Clear and Telecom for local NZ internet traffic.

20 April 2001

The installation of the Clear ATM was completed this week and as a single mode 155mbit fibre cable was installed the multi-mode ATM controller in the 7507 had to be changed to a single mode type. This is a Cisco PA-A3-OC3SMI enhanced ATM controller and is interfaced via a VIP2-50 processor card to the 7507 system.

A major upgrade to KC's power system was commissioned this week as a new 48 volt DC power supply was installed. This supply will provide a battery backed UPS for all of KC's Cisco systems and many other devices on the KC network. As part of this change the AC mains power units in the Ciscos have all been changed to 48VDC power units. A 1100Watt sine-wave inverter will provide AC power to those computers that cannot easily be chnaged to a 48Volt PSU.
The power system consists of a mains powered 56Volt constant voltage charger producing 2.5 Kilowatts output and four 12 volt 110Amphour sealed batteries configured as a 48Volt array. These batteries will provide power for up to 4 hours in the event of a mains failure although the main purpose of the system is to prevent mains power surges/spikes reaching KC's routers and computers AND prevent systems resets due to power brown-outs or short duration black-outs.

To further increase the resistance to unexpected electrical interference the major devices on the KC network will be changed to fibre (FX) ethernet interfaces and the complete KC ethernet LAN will connect to the Cisco 5505 switch via a 12port 100baseFX controller.
Initially there are FX connections to the Cisco 7507 routers, other devices will be changed as FX interfaces become available.

10 March 2001

A new Cisco 7507 router chassis was purchased last week, the Cisco 7505 system has been sold to another ISP in New Zealand.
This now allows a fully redundant almost identical system as a backup to KC's core 7507 router.

2 February 2001

With installation of Telecom ATM at KC and impending installation of Clear ATM circuit the routing equipmentat KC has been updated over the last three months.
The main router is still a Cisco 7507 but just about all of the interface cards and controllers have been changed.
A backup router, a Cisco 7505 has been obtained and is being online purely as a backup in the event of any failure of the 7507 chassis.
The 7507 now has three VIP2-50 controllers and one VIP2-40 controller. Interface (PA cards) are now two 155Mbit ATM, one a single mode and the other a multimode fiber connection. The SM card provides the interface to the Telecom ATM. A new Fast ethernet 2 port card provides two 100baseTX interface and the existing single port 100baseFx controller is retained.
Gone are G703 and several two port channelised E1 cards, a new eight port channelised e1 card is used on a VIP2-40 controller to provide stacked wideband DDS interface and one PRI interface. A four port serial card is retained to provide one port for the 2meg DDS between the new offices and Highland Ave in Titirangi. This circuit will be moved to ATM in the near future and the four port serial card will be removed.
At least two of the stacked wideband DDS will close in the near future as customer DDS circuits are converted to Frame Relay and connected to the Telecom ATM.
The current hardware config of the 7507 is:
Vip2-50 4/128ram with PA-FE-FX and PA-2FEISL
Vip2-50 8/128ram with PA-A3-OC3SMI (to Telecom ATM)
RSP4 128ram
Vip2-50 8/128ram with PA-A3-OC3MM (to Clear ATM)
Vip2-40 2/64ram with PA-MC-8E1/120 and PA-4T+

Spare parts carried for the 7505 include:
Two Vip2-40 2/32
PA-A3-OC3SMI
PA-A3-OC3MM
Two PA-2CE1/120

The Cisco 7505 provides a channelised E1/PRI interfce for one Centrex PRI port and three 10baseAUI ethernet ports for connection to the telehoused server network and the PlaNet ISP network.
The 7505 router is currently configured with the following hardware:
RSP2 128ram
VIP2-40 2/32 with PA-FE-FX
MIP2 dual E1/120 channelised E1/PRI ports
EIP6 six port 10base AUI ports

28 November 2000

A PC system, Intel II 400, was configured today as a WCCP cache server. This runs Linux with Squid cache software.
This is a transparent cache system that comunicates with the 7507 router to provide cache facilities for port 80 requests via the outbound international data ports on KC. Presently all outbound data is routed via the connection to Telecom's Global Gateway and the Cisco 7507 uses WCCP cache protocols to communicate with the PC system.
Resources in this PC are limited to about 10Gb of cache disk space although this is sonn to be increased to over 60Gb.
A second WCCP cache system based on a Sun Netra1120 with dual 400Mhz Ultra CPUs, 512Meg memory and 36Gb of wide SCSI disks will also be brought online by end February 2001.
