Product Description
Juniper Power Supply EX-PWR-930-AC New
The Juniper Power Supply EX-PWR-930-AC EX Series RPS The Juniper Networks EX Series acts as a backup device that provides redundant power to up to 6 connected Juniper Networks EX2200 and EX3300 Ethernet switches, with or without Power over Ethernet (PoE). The RPS ensures operational continuity following a main power supply or power feed failure, and can be easily managed and configured from the command-line interface of any connected EX Series switch.
The EX Series RPS supports a number of key features:
- The EX Series RPS can be connected to a maximum of six switches (any combination of EX2200 and EX3300s) using RPS switch connectors.
- An EX Series RPS can accommodate up to 3 hot-insertable, hot-removable, field-replaceable power supplies. All three power supplies must be the same type, and currently only the EX-PWR3-930-AC power supply is supported. Mixing different types of power supplies is not supported.
- The EX Series RPS can power up to three switches simultaneously (out of a total of six switches connected to the RPS) when all three power supplies are installed.
- The EX Series RPS provides integral protection against high-voltage input and output, as well as against short circuits, ensuring network continuity.
- The EX Series RPS operates in parallel with the main power supplies of the connected switches, providing backup power based on the connected switches configured priority and port number. By default, all switches share the same priority and precedence is based on connector position.
- Switch priorities can be reconfigured from the switch command-line interface (CLI) to supersede priority based on connector position. In the event of a power feed failure on a connected switch, the EX Series RPS automatically senses the switch's power needs (PoE or non-PoE) and delivers adequate uninterrupted power to the switch, ensuring network continuity with no switch reboot required. When the switches internal power is restored, the EX Series RPS stops supplying power to that switch and instead delivers power to any other switches that require backup power, based on their configured priority. A single power supply in the EX Series RPS can actively back up either one or two non-PoE switches.
- The EX Series RPS can be mounted on a 19-inch equipment rack or cabinet using mounting brackets.
- The EX Series RPS can also be mounted in the same rack or cabinet as the supported switches.
- The EX Series RPS is managed and configured from the CLI of any connected EX Series switch.
