Brand new switches available. They were purchased for a project, but the project never went though. This is ideal for small ISPs or offices who want a powerful yet affordable managed network switch. We are getting rid of these equipments, that is why the price is so low. Just Tk48,000 for a 48 port L2 Managed Network Switch. Still packed and not opened. This one does not have any PoE ports. All 24 ports are regular ethernet ports. You can visit us to inspect the products before you buy. Price can be negotiated if multiple units are purchased.
