That sort of hardware can last forever. At a previous employer, we had in the office a second-hand Cisco Catalyst 3548XL switch (it still had an asset tag from the previous company the boss had founded). According to the Cisco documentation I looked at back then, not only was that model long out-of-life, but also its successor was long out-of-life. And other than a couple of dead ports, it still worked perfectly; it won't surprise me at all if it's still in use today.
