Stack Connections
The switches have front‐panel RJ45 connectors for connections in a stack configuration.
The stacking cables used for the connections are standard Category 5 or better UTP cable.
Redundant Power Supply Capability
The SecureStack A2 has power supply redundancy capability when connected to an
optional external redundant power supply (RPS). If the internal power supply fails, the
RPS assumes the entire load of the SecureStack A2 without interrupting network traffic.
The internal power supply and RPS each have their own AC power connection, which
enables the connection of each power supply to a different AC power circuit for
additional AC power source redundancy.
Connectivity
The SecureStack A2 connects to Ethernet networks or workstations by means of the fixed
front panel RJ45 connectors and two fixed fiber‐optic LC connectors. For more
connectivity information, refer to Chapter
Management
Management of the module can be either in‐band or out‐of‐band. In‐band remote
management is possible using Telnet, the Enterasys NetSight
or the WebView application. Out‐of‐band management is provided through the DB9
Console port connector on the front panel using a VT100 terminal or a VT100 terminal
emulator.
Switch Configuration Using WebView
Enterasys Networks' HTTP‐based Web management application (WebView) is an
intuitive web tool for simple management tasks.
Caution: The A2H123-24 is not PoE-compliant. Do not connect a SecureStack PoE
Redundant Power System (C2RPS-POE) to the power connector. Otherwise, damage to
the device may result.
Precaución: El dispositivs A2H123-24 no cumple con el estándar PoE (power over
ethernet). No conecte una fuente de poder redundante (RPS) SecureStack PoE (C2RPS-
POE) al cable de corriente. De lo contrario, el dispositivo puede dañarse.
