Note to self - must learn to count
There I was feeling self-satisfied - ages ago I said we needed to upgrade one of our switches and finally it began to fail so they HAD to listen to me, and bought a new switch to my specification.
That's where it all went wrong. I thought I had counted the number of connections and given that we are very very short of money I thought we could get away with a 24 port even though the dead switch was a 48 port. So I merrily ordered it, the caretaker screwed it to the wall, all was fine and dandy until....he had a cable left over. There were 25 connections to that switch.
Now what do I do?

Do you have any old 4-port hubs/switches laying around? Or, better still (two birds with one stone) any access points that can be convienantly relocated?
Failing that, just hope nothings plugged in on the other end

If you've got a spare power socket, what about a popping a cheap 5port switch on top? Plug it into one of the ports on the 24port then plug your extra two cables into it? I know it's not ideal, but should work OK!
TP-Link TL-SF1005D 5 Port Fast Ethernet Switch | TL-SF1005D (10/100) or TP-Link TL-SG1005D 5 Port Gigabit Switch | TL-SG1005D (10/100/1000) should work!

Wander round the rooms and check if there are spare ports not in use that you could un-patch.

No spare switches or power points locally unfortunately. I have tracked it to one of the two computers IN the res mat room. They shouldnt be there anyway so I've just put a note on the disconnected one. Tough

Explain that because you are a computer scientist you learned to count from zero. So technically you only needed 24 connections, but the pesky switch manufacturers completely ignore convention and count from one. Then buy another switch :-)

They don't work on the switch, in fact it would make the problem worse as Witch would then need 26 ports instead of 25

the switch cant accept a module to give you another port can it? (and lots of hp 24 port switches have 26 ports)

Is your 24 port switch a PoE switch? HP do an 8 port switch that can be powered entirely by a PoE cable into its first port - the 1810-8G v2. If your main switch is PoE capable you could run that 8 port switch with only a single network cable (and have a total of 30 ports available)

Phone ICT Direct and see what they have on their shelves!

Use an IEC Y-split cable so you can power two switches (when you source another) from the one power socket.

Phone supplier and have a bit of a rant saying you definitely ordered a 48-port switch
When they challenge you that the order does state a 24-port - counter with how rubbish their site is (blame sloppy coding at the back end resulted in a SQl query not being correct and queried the wrong switch when you submitted the order) and that you specifically requested the 48-port switch and that you want it rectifying as soon as possible
Claim it is faulty (It's returning a BAD_PORT_COUNT_CHECKSUM error when you connect to it.)
Replace it with a 48-port switch
