Industrial – Unmanaged: BLUEBERRY BU-102 SERIES

Product Description

The CloudberryAERO CM-2900 Series - Fully Rugged 19" Rack Mounted 32 Port Managed Airborne Gigabit Ethernet Switch with PTP GMC, TC/SC and Mighty Mouse Connectors

 The CloudberryAERO CM-2900 Series offers a fully rugged, Commercial Off The Shelf (COTS), 32 port Gigabit Ethernet switch with PTP Grand Master Clock support with free running clock as time base optimized for aircraft and military network systems applications.

Featuring advanced Layer 2 networking with 32 ports of non-blocking wire-speed 10/100/1000Mbps connectivity, an integrated management processor, the CloudberryAERO CM-2900 Series enables end nodes to operate with a synchronization accuracy better than 30ns across the operating temperature range: (-15 to +70C) and extreme shock/vibration conditions.

Featuring Mighty Mouse connectors in an aluminum chassis, the unit serves as an ideal solution for connecting IP-enabled embedded devices in a demanding environment.

The CloudberryAERO CM-2900 Series implements the Precision Time Protocol (PTP) according to IEEE 1588 Std 2002 (PTPv1) and IEEE 1588 Std 2008 (PTPv2). With its unique PTP implementation and embedded PTP version translator, the CM-2900-Series allows Slave Clocks of either PTPv1 or PTPv2 to co-exist in the same network.

This fully managed, Layer 2 Gigabit switch provides a powerful set of carrier-grade networking features, including support for IPv4 multicast traffic filtering according to static filters or IGMP snooping, Virtual Local Area Networks (VLANs), port control (speed / mode / statistics, flow control), Quality of Service (QoS) traffic prioritization, Link Aggregation (802.3ad), SNMPv/1/v2/v3 management, secure authentication (802.1X, ACLs, Web/CLI), redundancy (RSTP/MSTP) and port mirroring.

The CloudberryAERO CM-2900 Series is tested according to RTCA DO-160G.

To enhance reliability, the unit features military temperature grade components, an isolated power supply that protects against voltage surges, spikes and transients and no moving parts.

Key Features

The CloudberryAERO CM-2900 Series offers switches with and without time synchronization support for in-flight data communication.

Time Distribution The CM-2900 Series is available as a reliable and accurate (< 20 nanosecond) PTP Grand Master Clock and Transparent/Slave Clock according to IEEE 1588 Std 2002 (PTPv1) or IEEE 1588 Std 2008 (PTPv2) standards.
The PTP Grand Master Clock contains a built-in high accuracy GPS receiver.
Interoperability The CM-2900 Series supports all relevant IEEE Ethernet standards. Interoperability with other PTP devices are ensured based on extensive testing.
Version Translation The CM-2900 Series with its unique embedded PTP version translator feature, allows Slave Clocks of both PTPv1 and PTPv2 to co-exist in the same network
Management The CM-2900 Series offer full management based on HTTP, telnet or SNMP v1/v2/v3 and implements a Cisco like CLI
Rugged The switch is designed for demanding aircraft and military environmental requirements. The platform offers a wide operating temperature range [-15 to +70Cº] with ruggedized military approved connectors. The unit is approved according to RTCA DO 160G.
Version Translation The CM-2900 Series offers advanced filtering capabilities. Multicast filters can be set on the switch either based on IGMP snooping or by manual configuration of static filters
VLAN 802.1Q Port based VLAN (static) or dynamic VLAN according to IEEE802.1Q are supported.
Security Security according to IEEE802.1x is supported.
Connectors The CM-2900 switch is configured with up to 43 connectors;all of the Ethernet port connections are located at the rear side. The Management port, CLI, battery holder, Ground connection and LEDs are on the front side.
