Batch Versus Individual Setup - Lantronix SecureLinx Spider User Manual

Second Ethernet Port
The Spider incorporates a hardware Ethernet switch connecting the external two ports
and the internal CPU for many possible configurations. The first port is required for
connection to the network.
Potential uses for the second Ethernet port:
Tying all the Spiders in a rack together so that only one external network connection is
required. While this configuration physically is a chain, logically each Spider is
addressed directly from the outside network. Because the data from the Spider at the
end of the chain does need to traverse the entire series of switches, latency increases
and hence responsiveness degrades with the number of devices. A maximum of 16
Spiders in a chain is recommended, though this is a function of the type of application
and acceptable level of response. If the switch to which the Spider chain is networked
supports Spanning Tree, the first and last devices in the chain may both be connected
to provide resilience against a single point failure.
Connecting to the attached server's LAN management port; an external management
network can then interface to both the Spider and the server via one cable.
Connecting to the attached computer's main LAN port. If physical isolation of
management data and user data is not a concern, a single LAN cable can provide
connectivity to both Spider and computer, conserving a switch or router port.
Aggregating any other Ethernet connection as a general-purpose switch port.

Batch versus individual setup

It may be necessary to deploy a batch of Spider devices at once. In that case, stage them
on a bench for pre-configuration before attaching them to their respective computers.
Some tips for configuring a batch of Spiders:
The keyboard/video/mouse connections are not required for setup. All you need are a
source of power and a serial connection to set up the network parameters, and an
Ethernet connection to access the administration user interface.
The quickest and easiest source of power is the auxiliary DC input. DC supplies are
available from Lantronix under order number 520-085-R. If using a third party charger
with mini-USB connector, make sure it is 5V@1A regulated ("Efficiency level III" or "IV"
is an indicator that it is a switching supply and hence well regulated) with an adequate
cable.
Tag each Spider with its IP address or write it on the serial number label on the
bottom.
