Description
Product details:
A4H254-8F8T P0973JP Fast Ethernet Switch is a store and forward stackable switch that can
be adapted and scaled to meet your network needs. These stackable switches provide a
management platform and uplink to the network backbone for stacking groups of up to eight
A4H254-8F8T P0973JP switches. You can also use redundant power supplies in conjunction
with these switches to help prevent an down switch or internal power failure in the AC power supply due to the following reasons.
You can install stackable switches on a flat surface or in a standard 19-inch rack and configure
stackable switches to use WebView applications, CLI switching commands, and/or SNMP.
A4H254-8F8T P0973JP Stacked switches can be connected to Ethernet or workstation connectors,
SFP ports, or Gigabit Ethernet ports by RJ45, depending on your model configuration. This SFP port
supports optional hot-swappable transceivers. The built-in RJ45 stack port on the 1000Base-TA4 switch
can be configured as a standard 10/100/1000Base-T port to switch when the devices are in independent mode (non-stack mode).
A4H254-8F8T P0973JP Stack connection
The switch has an RJ45 port on the front panel for connection in stack configuration. Stacking cables for connection must be standard Category 5 or better UTP cables.
A4H254-8F8T P0973JP Redundant power supply capability
When connected to optional external devices, the A4 has power redundancy features Redundant power supplies:
•STK-RPS-150PS, 150 Watt DC power supply, redundant power supply for A4 switch. If the internal
power supply fails, the RPS automatically assumes the role of the internal power supply without interrupting
network traffic. Both the internal power supply and the RPS have their own AC power supply connections.
Each power supply can be connected to a different AC power supply with additional AC power supply redundant power circuits.
