Universal Equipment Modules
The Meridian 1 System is comprised of Universal Equipment Modules
(UEMs), each containing everything needed (card cage assembly, power
supply, I/O cabling, etc) to support a specific system function. These UEMs
are assembled up to four high on a pedestal, to form a column. The pedestal
contains a central Power Distribution Unit (PDU), cooling fans, air filters,
and a System Monitor circuit. At the top of each column is a Top Cap,
which consists of two air exhaust grilles and a thermal sensor assembly that
works in conjunction with the System Monitor. Systems are comprised of
one or more columns. Each Universal Equipment Module is available in
AC or DC powered versions.
The Universal Equipment Modules are constructed of die cast aluminum,
providing strength and durability. For ease of access each module has
removable front and rear covers. All cable routing between the module and
the Main Distribution Frame (MDF) is handled through the rear of the
module. Cable exit can occur at the top, to access overhead cable racks, or
at the bottom to take advantage of raised floors. Universal Equipment
Modules are assembled on a pedestal that houses a central Power
Distribution Unit, cooling units and system monitor circuitry. The pedestal
can be equipped with either leveling feet or casters. UEMs may be
assembled in columns up to four high.
The following Universal Equipment Modules are available:
-
