The Black Box LES1516A-9MT is a console server adapter that converts an RJ45 interface to a DB9 male (DB9M) connector, enabling dumb terminal access to serial-managed devices through compatible Black Box console servers. If you manage network equipment — routers, switches, firewalls, PDUs — via out-of-band serial console ports, this adapter bridges the RJ45 patch-cable runs from your Black Box console server to the DB9 serial ports on your managed devices without requiring a separate rollover cable retermination.
The LES1516A-9MT is designed to work within the Black Box LES console server ecosystem, providing the physical-layer pinout translation needed for reliable serial console connectivity. Deploying it is straightforward: plug the RJ45 end into the appropriate console server port and the DB9M end into the serial console port of the target device. No drivers, no configuration — the adapter is purely passive hardware at the connector level.
For data center and network operations center (NOC) environments running console servers for out-of-band management, having the correct adapter per device type is essential. The wrong pinout means no session — this adapter addresses the common RJ45-to-DB9M translation needed by a wide range of Cisco, Juniper, and similar vendor equipment that ships with DB9 console ports. Review your target devices' console port pinouts against the Black Box documentation before deploying at scale across a rack.
Contact pre-sales engineering to confirm compatibility with your specific console server model and managed device combination before ordering in quantity — LES1516A-9MT (also searched as LES1516A 9MT) is one of several adapter variants in the Black Box console access line, each targeting a different connector and pinout combination.
Q: What does the LES1516A-9MT adapter do?
A: It converts an RJ45 interface from a Black Box console server to a DB9 male connector, allowing serial console access to devices with DB9 console ports such as routers, switches, and firewalls.
Q: Is the LES1516A-9MT compatible with all Black Box LES console servers?
A: It is designed for use within the Black Box LES console server family. Confirm your specific console server model against Black Box's compatibility documentation before deploying at scale.
Q: Does the LES1516A-9MT require any drivers or software?
A: No. The adapter is a passive hardware connector that performs physical-layer pinout translation. No drivers or configuration are required on the adapter itself.
Q: Can this adapter be used with non-Black Box console servers?
A: The adapter is engineered for the Black Box console server ecosystem. Use with third-party console servers is not confirmed by the manufacturer and should be validated before deployment.
Q: Where does the LES1516A-9MT fit in a typical NOC or data center rack?
A: It connects inline between the RJ45 console port on a Black Box console server and the DB9 serial console port on a managed device, enabling out-of-band management without separate rollover cables.
The LES1516A-9MT is the kind of part that stops a NOC deployment cold if it's missing or ordered wrong. It handles the RJ45-to-DB9M pinout translation that Black Box console servers require to reach serial-managed devices — a physically simple but operationally critical adapter.
Technical Highlights:
Deployment Considerations:
The LES1516A-9MT is the right choice for NOC and data center teams standardized on Black Box LES console servers who need to reach DB9M-ported managed devices through a single, reliable passive adapter — particularly useful when building out a structured out-of-band management plane across a mixed-vendor equipment rack.
