The SCS can help troubleshoot your networking environment. The SCS is a
"listening" system that monitors messages (ASCII data, server error information, etc.)
from the serial ports of the device to which each Port is connected. The SCS captures
the data by writing it to a port buffer that can hold 256K bytes of data per port. This
buffered data gives the sysadmin a history of console port messages that can be
reviewed for troubleshooting a connected device. Having access to the console port
messages can make problems easier to identify, minimizing downtime. In most cases
the sysadmin can save the buffered data from each port buffer to another server
(e.g., via NFS) in your network. This is important to note because the Port data
(buffered) is stored in RAM and will be lost if the SCS is powered down.

NOTE: Console port messages are stored in RAM and will be lost when the
SCS is powered down.
1.4.1 SCS80R, SCS160R and SCS320R Hardware
The SCS80R, SCS160R, and SCS320R models offer hardware redundancy for power,
network and console ports. Features include dual NIC inputs, dual console port inputs
and hot-swappable Power Modules with discrete inputs. This allows the customer to use
redundant power sources with the SCS system and, if necessary, can be field-replaced.
Power supply status alerts the system administrator in the event of a power failure from
one of the power supplies.
1.4.2 SCS480R Hardware
The SCS480R offers redundant, hot-swappable, front-panel-accessible power supplies,
dual NIC interfaces, dual console ports and 48 serial ports.
1.4.3 Sentinel 32 Hardware
The Sentinel 32 offers redundant power supplies as described in Section 1.4.1. The dual
network and console ports are also field replaceable. A dual network/console/modem
module is available which replaces the second console port with an analog modem. In
addition, the Sentinel uses hot-swappable circuit modules that allow for field
replacement of groups of eight serial ports without affecting the other ports.
