Refurbished Phone Chassis for Telephone Systems
A phone chassis is the main unit of a telephone system: the cabinet or control unit that holds the processor, power supply and card slots. The cards and modules that run your lines and extensions plug into it or connect to it. This range covers refurbished chassis, controllers and complete systems from Avaya, Nortel, Panasonic, Mitel, Siemens, ShoreTel, Samsung, NEC, Cisco, Inter-Tel, LG and BT Business.
You buy a chassis to replace a failed unit, rebuild a system from spare parts or keep a spare on the shelf. Examples include the Mitel 3300 CXi II, Nortel BCM450, Panasonic KX-TDA100 and Siemens HiPath 3550. For single cards, see system cards. For an overview of whole systems, start at telephone systems.

How to choose a phone chassis
Match the system family
A chassis runs only its own maker's cards, phones and software. Read the model on your current unit, such as Mitel 3300 CXi II or Samsung OfficeServ 7200, and choose the same family so your cards and handsets carry over.
Check size and free slots
Most families come in several sizes. Panasonic, for example, made the KX-TDA30 and KX-TDA100, and Samsung the OfficeServ 7030, 7100 and 7200. Count the cards and ports you need, then pick a chassis with spare slots.
Controller or expansion cabinet
Some units are main controllers. Others are expansion cabinets that only add capacity to an existing controller, such as the Nortel MG 1000 chassis expander. If you need a working system on its own, choose a controller or complete system.
Software, licences and memory
Many systems hold their software and licences on the control unit or on a memory card, such as the system SD card in an Avaya IP500. Licences may not move from your old unit, so check this before you swap.
Repair before you replace
A failed chassis is often down to one part, such as the power supply or processor. Our repair service may get your unit working again. If not, a refurbished chassis from the same family keeps your cards and phones in use.

Questions
What is a phone chassis?
A phone chassis is the cabinet or control unit at the heart of a telephone system. It holds the processor, power supply and the slots for line, extension and voicemail cards. You may also see it called a telecom chassis, control unit or KSU (key service unit).
Does a chassis come with cards fitted?
It depends on the listing. Some units are a bare chassis or controller, others come with cards or extensions, such as the Avaya IP400 Phone System + 4 Extensions. Check the product title and description, and ask through the quote form if you need a set card layout.
Will my existing cards fit a replacement chassis?
Usually, if the new chassis is from the same family and generation. Cards often fit several sizes within one family. They rarely fit a different family or a much older generation. Match the part numbers on your cards to your chassis model, or send them through the quote form.
