1000 Mbps.
Note: When using the RJ45 ports on the SecureStack A2 for 100 Mbps operation use
Category 5 UTP cabling with an impedance between 85 and 111 ohms.
The fixed SecureStack A2 ports are capable of operating at 10 and 100 Mbps. This is
accomplished by the SecureStack A2 when Auto-Negotiation is enabled. This enables the
SecureStack A2 to automatically sense the transmission speed of the other device and
adjust for the speed accordingly.
