===LINX Manchester===
Launched in April 2012 IX Manchester, now known as LINX Manchester was initially a single-site platform based on a stand-alone Brocade BigIron RX-16 switch, repurposed from the primary LAN in London. A new design extends the network to two new sites – M247's Ice Colo & Joule House and brings in completely new hardware from Extreme Networks.

The new network will be configured as an EAPS protected ring, topology currently used for the secondary LINX LAN in London. All sites will use a Summit X670v switch, capable of connecting 48x10&nbsp;Gb member ports. Telecity Williams will also have a smaller Summit X460 switch for terminating slower ports.

The links between sites will be provisioned on a dark fibre provided by NTL and lit by LINX with the use of SFP+ DWDM transceivers and passive DWDM MUX units. Initial ISL capacity will be configured at 20&nbsp;Gbit/s but easily upgradeable to 80&nbsp;Gbit/s if required.
