This page explains the different switches options that we support, and the process for purchasing new switches, or replacing existing switches.
We will take delivery, configure and install the switches for your department, and keep you updated on the progress of each new request.
We keep stocks of supported models or their direct equivalent for their supported lifetime (a guaranteed minimum of 5 years, currently it is more than double that) and in the unlikely event of switch failure, aim to replace failed device the same working day where possible.
To ensure a consistent user experience, we aim for a maximum contention ratio of 10:1 on any uplink – there is a little more detail on each switch model where is this relevant.
As part of the UCL cost and energy reduction strategy, all new client switches must have the ability to provide Power over Ethernet (PoE), which is necessary for both wireless, and Voice over IP (also called IP Telephony) deployment.
Upgrades outside of building refurbishments will require the department to fund the full cost of the new switches or submit a business case to ISD for central funds. Due to budget constraints, we cannot “buy back” used switches, but we will redeploy or store them for you as needed.
ISD Network Services will provide one wired port per user as standard. Building occupancy figures will be based on the numbers provided to ISD by UCL Estates. Where additional capacity is required ISD Network Services will conduct a survey to verify that no ports are patched but unused. Between 2014-01-01 and 2015-01-01 ISD Network Services will be trialling a new approach to capacity increases. Subject to agreement by Network Services that additional capacity is required, extra switches will be provided without cost to the department within this period.
Further details of this pilot and can be found on the IT Managers' Wiki.
This switch has 48 1Gb ports and 10Gb uplink. If you do not have any specialist requirements, this is the switch you should use.
This switch should be used where occupancy is, and always will be, less that 20 users on a single floor.
Uplink and Stacking Modules
In addition to the cost of a switch, you may also need interface modules. Exactly what is needed depends on what you have currently and what speed you’ll be using.

Non supported switches
The use of non-supported switches (especially non-managed, or “dumb” switches) may mean that we are unable to assist with network problems until these are removed. This is not just us being awkward, in some cases it can make the troubleshooting impossible, because they can mask serious issues, as well as not being able to detect network loops.
