Page 14: Installation
NTI SERIMUX SERIES SSH CONSOLE SWITCH INSTALLATION This NTI switch was designed to be mounted to a rack or to set on a desktop. It includes rack mount ears to make attachment to a rack easy, and rubber feet to be applied to the bottom of the case if it will instead sit on a flat surface. If this will sit on a flat surface, simply apply the rubber feet to the bottom of the case in each of the 4 corners. -
Page 15: Cable Connections
NTI SERIMUX SERIES SSH CONSOLE SWITCH Cable Connections Connect a serial console to the port labeled "CONSOLE" on the SERIMUX using a serial cable with an RJ45 male connector (Cat5 patch cable supplied). This will be the default administrator device. (Figure 3) Connect each additional serial user device or host device to be connected by the SERIMUX to any remaining port (1- 4/8/16/24/32) using a serial cable with an RJ45 male connector (see cable specification on page 70). -
Page 16: Dual Power Option
Figure 5- Power connections for SERIMUX with Dual Power option DC Power Option The SERIMUX-S-x-48V has connections on the rear for a user-supplied 48VDC power supply. This is typically used when the SERIMUX is installed in a Telecom environment. The SERIMUX-S-x-48V will accept a DC power source between 36~72VDC (48VDC nominal), positive or negative polarity. -
Page 17: Connect Sensors
Connect Sensors (not supported as of this printing) The SERIMUX-S-x has two RJ45 connectors for attachment of up to two sensors to monitor environmental conditions. Sensors can be connected to measure temperature (ENVIROMUX-STS), humidity (ENVIROMUX-SHS), temperature and humidity (ENVIROMUX-STHS), temperature and wide range humidity (ENVIROMUX-STHS-99). A sensor can also be connected to detect liquids (ENVIROMUX-LDSx-y). -
