APPENDIX D: Using an Optional Serial Access Unit with the R-Port
Appendix D. Using an Optional
Serial Access Unit (IPMI Supported)
with the R-Port
D.1 Background
Using the R-Port on the ServSwitch unit’s rear panel, you can add up to 16 serial
access units using a specialized daisychain technology. The ServSwitch includes
integrated control functionality that allows you to monitor and configure the
devices with the RS-232 serial port using the interactive Web interface. To
minimize space and infrastructure requirements, the serial access unit uses a single
RJ-14 cable (included with the Serial Access Unit, KV9-SRL) to carry both power
and the data signal. All configuration settings are stored separately in each
attached Serial Access Unit in nonvolatile memory so that they will not be lost in
the event of a power outage or disconnection.
D.2 Connecting the Serial Access Unit to the ServSwitch
The RJ-14 cable for attaching the Serial Access Unit (KV9-SRL) via daisychain is
similar to a phone cable. For the first computer, connect the RJ-14 cable to the
R-port on the ServSwitch unit’s rear panel. Then, connect the opposite end of the
RJ-14 cable to the Serial Access Unit’s RJ-14 port. There are two RJ-14 ports on the
Serial Access Unit; choose either one of them. Once you have added the first
computer to the ServSwitch by using the Serial Access Unit, you can connect the
second computer by using the second Serial Access Unit. Use the second RJ-14
cable to link the first Serial Access Unit and the second one. Then, you can link up
to 16 computers.
D.3 Configuring/Viewing the Serial Access Unit Through the Web Interface
Once you have one or more Serial Access Units connected, you will able to
configure and manage them through the Web interface. You may need to modify
the default settings on the ServSwitch to match your various Serial Access Units’
default configuration. Consult the documentation that came with your Serial
Access Unit to determine if you need to modify the default settings to complete the
installation. To be able to configure your Serial Access Unit, you must be logged in
as
admin
. Other users will be able to view which devices are active but cannot
configure them.
