The Hirschmann Spider 8TX (P/N: 943376-001) is an un-managed Industrial ETHERNET Rail-Switch that features store and forward switching mode, Ethernet and Fast-Ethernet (10/100 Mbit/s), 8 x 10/100BASE-TX, TP-cable, RJ45 sockets, auto-crossing, auto-negotiation & auto polarity. It features a space saving design and is recommended for small networks. The Spider 8TX includes plug and play capabilities, LED indicators to show the current status and management software. It is made to stay resilient against shock and vibration, as well as electromagnetic interference. It has a very efficient power consumption, making the Spider 8TX a cost effective addition to a network.

  • (8) 10/100BASE-T(X) ports allow for single devices or complete network segments.
  • Frame Switching Functions
    • Store and Forward - only forward valid frames and discards invalid frames
    • Multi address capability - learns up to 1,000 addresses. This becomes necessary if more than one terminal device is connected to one or more ports.
    • Learnt addresses - monitors the age of the learned addresses. The SPIDER deletes address entries from the address table which exceed a certain age (300 seconds).
    • Tagging - IEEE 802.1 Q standard designates the VLAN tag to be included in a MAC data frame for the VLAN and prioritizing functions.
  • Functions of the TP/TX Interface
    • Link control - monitors the connected TP line segments for short-circuit or interrupt using regular link test pulses
    • Auto polarity exchange - If the receive line pair is incorrectly connected (RD+ and RD- switched) polarity is automatically reversed.
    • Auto-negotiation - a procedure in which the switch automatically selects the operating mode of its 10/100 RJ-45 ports.
    • Auto-crossing - automatically configures its port for the correct transmit and receive pins
  • Additional Functions and Features
    • The SPIDER 8TX will be reset when input voltages falls below a threshold After a reset in will re-initialization.
  • Display Elements
    • Equipment status - provides information about statuses which affect the function of the entire SPIDER.
    • Power - when lit indicates supply voltage present
    • Port Status - display port-related information.
    • Data & Link status - indicates data traffic and rate
