5.1 Serial Port expanders
GSL supply a range of serial port expanders which provide additional serial
ports via a USB connection to the NAM. They are single-height (1U), nineteen-
inch rack-mounting units with part numbers CMG-NSP-RM08, CMG-NSP-RM16
and CMG-NSP-RM24. The final two digits of the part number indicate the
number of ports.
These systems have a single USB type B connector on the front panel and
eight, sixteen or twenty-four nine-pin serial ports on the rear panel. Because
the serial ports require more power than is available from a single USB
connection, a 5 V DC power input is required.
To deploy these systems, connect a suitable 5 V DC power supply and then
connect the unit to the NAM using a USB Type A to USB Type B cable. The NAM
will automatically detect the new serial ports and provide automatically-
generated names for them, depending on any previously-connected units.
5.2 Network accessible storage
GSL supply NAS (network-accessible storage) units, part number CMG-NAS-
RMExxx (where xxx indicates the capacity) which provide additional storage
capacity for the NAM and extra resiliance, through the use of RAID technology.
They are single-height (1U), nineteen-inch rack mounting systems suitable for
data-centre use and each unit holds four drives, providing up to 12 TB of
storage (less if mirroring is enabled). The total power consumption is around
30 W.
The CMG-NAS-RME
xxx
works with 2.5-inch or 3.5-inch SATA hard drives
mounted in hot-swappable drive carriers and includes two Gigabit LAN ports for
multi-IP settings and port trunking (7 bonding modes).
