MNSW-503 3-Port Ethernet Switch

3-Port Ethernet Switch (1000BASE-T, SNMP, IEEE 1588 V1/V2 GRANDMASTER)

The MNSW-503-3 is a three-port 100BASE-T Ethernet full-duplex switch module for use in the TTC MnDAU miniature networked product line. It provides upstream and downstream Ethernet chaining to any MnDAU stack in which it is installed. The single-height stackable module provides packet switching and IEEE 1588-2008 time distribution to support networked data acquisition components and systems.

The MNSW-503-3 minimizes the use of ports on more expensive switches by allowing more than one miniature stack to share one downstream port on a larger switch. It functions as an unmanaged switch, is preconfigured with all necessary routing information and does not require a MAC or IP address. The MNSW-503-3 has a switching capacity of up to 1.07 million packets per second and supports an unlimited number of multicast addresses.

The number of data acquisition units that can be daisy-chained together using MNSW-503-3 is dependent upon the total bandwidth produced by each connected miniature stack up to a maximum of 16. Each MNSW-503-3 adds a maximum of 40 nanoseconds of uncertainty to precision Time Protocol (PTP) time as the timestamp data is switched. Symmetrical flow control on all ports is implemented using pause frames and guarantees that no packets are dropped due to contention.
