3: Installing the Spider Device
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 32
Perform the following steps to configure the mouse-to-cursor synchronization.
Windows Server
1. Select Control Panel > Mouse > Pointer Options.
2. Set the pointer speed to medium and disable Enhanced pointer precision.
Linux Server
1. Set Mouse Acceleration to exactly 1 and threshold to exactly 1.
2. Select Other Operating Systems on the Spider mouse settings page.
Solaris Server
1. Set the mouse settings by using the CDE control panel to “1:1, no acceleration” or “xset m 1”.
Mac OS X Server
1. Set the Spider device to Single Mouse Mode.
Telnet/SSH Connections to Serial Ports
To Telnet/SSH to a target computer serial port, you must Telnet/SSH to the Spider serial port first
and use connect serial CLI. This connects your Spider device to the target computer serial
port. The default settings are 9600 bps, 8 data bits, 1 stop bit, no parity, and no flow control. The
pinout of the included Spider cables match a standard DB9 COM port.
Cable Connections for KVM and USB
Connections for KVM and USB are integrated into the Spider device. Do not use extension cables.
Plug the Spider device directly into the ports on the host server. If using the Spider serial port, plug
the cable into the COM port on the server.
The second Cascade Ethernet port can connect to the Spider device to the target computer
management LAN port, or to a main LAN port, or to a Spider device chain. When connecting the
Ethernet ports, straight through or crossover cables can be used, because the Spider device has
auto-polarity and auto-crossover correction. Although the port marked Ethernet and the port
marked Cascade are both Ethernet interfaces, you must use the port marked Ethernet if using only
one Ethernet interface.
Perform the following steps when daisy chaining Spider devices.
1. Plug the outside network cable into the left Ethernet port of the first Spider device.
2. Connect the right Cascade port to the left port of the next Spider device in the chain.
3. Repeat as necessary. The last Spider device in the chain should have its right port
unoccupied, unless cabling in a loop for redundant connection.
Device Failure or Cable Break in the Daisy Chain
If a device fails or there is a cable break in the daisy chain, there could be a loss of network
connectivity for all devices downstream from the cable break or device failure. Avert this issue by
installing Spanning Tree in the switch or router to which the Spider device chain attaches. Then,
connect the last Spider device from its Cascade port to the same switch so that there is a
redundant outside connection.
