HP T5515: Hardware 


 


 

 



HP t5515 thin client

The HP T5515 I have was manufactured in August 2004.

HP describe this as...

The new competitively-priced Linux-based HP Compaq t5515 Thin Client provides freedom of choice and the security of a Linux client for server-based computing environments.

One thing that caught me out with this model (in terms of bidding for some eBay) is that, if you do a Google search on t5515, you find lots of hits from people offering replacement memory. Despite the previous comment I'd found (see below) I took this as meaning that they were fitted with a SODIMM socket without doing any further research. It turns out that there are two versions of the t5515: The PC538A and the PC542A. In respect of these HP's spec has the helpful(!) comment with respect to the USB ports: "2.0 or 1.1 depending on model" and then gives no further information.

Needless to say the ones I picked up were the 32Mb/64Mb version (Product # PC538A). Since I first added the t5515 to this site I've had a helpful email from Maciej Kaleta in Poland. Information on, and the photograph of, the PC542A model are down to him.

Power Supply

The unit requires a 12V supply. If yours came without one a unit can be easily sourced. I have bought suitable 12V 3A units on ebay that were advertised as being replacements for LCD displays. I'm not too sure of the exact dimensions required for the plug, but a 5.5mm external 2.1mm internal plug seems to fit. (Maplin stock one - part # AQ88V type E).

Expansion

PC538A

t5515 Circuit Board

Flash: The Flash memory is provided by a DOM (Disk On Module) fitted to a standard 44-pin IDE connector. You can see this in the top left of the picture. (Apacer board)

RAM: The RAM is soldered to the board and so fixed at 64MB.

From an HP briefing document:

"Going forward, new t51xx and t55xx thin clients will not have configurable RAM. For manufacturing economies of scale, RAM will be installed "down." The t51xx and t55xx units will not include a SODIMM slot."

RAM: The RAM is easily expandable - it is fitted in a SODIMM socket. Maciej successfully tried 256MB (hynix PC2100S, DDR 266MHz CL2.5) and 512MB (Elpida PC2700S) SODIMMs in the socket.

PCI: The PCI expansion slot is fitted to the motherboard.
