One Stop Systems' 8U carrier class
enclosure for mission-critical wireless, Internet, and telephony
applications is a feature-rich rackmount enclosure that puts
more functionality into less space than any enclosure of its
type and class. It includes a 14-slot backplane with the H.110
telephony bus, and four 300W power supplies. In addition, it
includes three hot-swap fans mounted below the card cage and
three hot-swap exhaust blowers above the card cage for optimal
cooling power. An optional system monitor is also a first-of-its-kind
6U CompactPCI board that allows the operator to monitor vital
system functions. Its internet-based firmware allows the technician
to monitor system functions remotely from any Internet connected
computer. An optional removable front door covers the entire
front of the enclosure.
Power supplies
The 8U encosure is equipped
with four 3U 8HP-wide modular power supplies.
Cooling
The enclosure offers three (3) tachometer
fans in individually removable canisters mounted below the card
cage and three (3) individually removable blower canisters mounted
above the card cage. The fans pull ambient air in through the
front of the enclosure and direct it up across the vertically
mounted boards. The blowers then pull the cooling air up across
the boards and out through the rear of the enclosure. This allows
for optimal cooling when one of the devices stops or fails to
operate properly. Fan rotation and the temperature of the card
cage is monitored and LEDs light when a faults occurs. Audible
alarms can also be added.
Storage modules
The four SCSI hard
drive canisters support SCSI hard drives equipped with SCA connectors
on the rear that plug into a backplane. The SCA connectors contain
the SCSI data signals as well as power and ground so each drive
is individually hot swappable. Drive mirroring and RAID (Redundant
Array of Independent Drives) levels can be employed, as the application
requires. The canisters mount vertically, stacked two above the
others. This allows up to 292GB of storage in only three 6U slots.
Optional
system monitor
The OSS System Monitor
is a 6U CompactPCI board with transition module. It provides
monitoring of temperature, fan rotation, DC voltage levels, door
opened or closed and CPU activity. It also controls the blower
speed, which reduces noise when the blowers are not needed. The
transition module, which mounts behind the backplane in the enclosure,
provides the interface to all the I/O including fans, blowers,
temperature sensors, relays, serial port and Ethernet port.
