Components
Power Supplies
Four power supplies with universal AC input provide power to the components in an
IOAM enclosure.The power supplies are installed in slots 15 and 18 on the rear side of
an IOAM enclosure.
Bezel
The bezel is a hinged cover on the front on the IOAM enclosure.
Cable Management System
There are two types of cable management systems: cable trays which manage the
fiber-optic cables at the module level, vertical cable guides, which manage cables
when installed on the modular cabinet.
Maintenance Switch
The maintenance switch is mounted in a standard 19-inch rack and provides the
communication between the IOAM enclosure and the OSM console.
Modular Cabinet
The modular cabinet is a 19-inch, 42 U high, industry-standard rack for mounting
modular components. It houses the IOAM enclosure, uninterruptible power supply,
extended run time modules, and maintenance switches. The modular cabinet comes
equipped with front and rear doors. In order to mount power distribution units (PDUs)
without occupying any U-space in the cabinet, the cabinet includes an extension, which
makes it deeper than the industry-standard rack.
Power Distribution Unit (PDU)
The PDU supports power outlets for the components in the rack. The PDU is installed
on a rack extender frame attached to the rack. For an IOAM enclosure, the IOAM
power supplies plug into the PDU.
UPS
For IOAM enclosures, a UPS is optional but recommended where a site UPS is not
available. You can choose to use any UPS that meets the modular cabinet power
requirements for all enclosures being powered by the UPS. One UPS option to support
the IOAM enclosure is the HP R5500 UPS.
The standard configuration for cabinets with an R5500 XR UPS assumes that you also
install one extended runtime module (ERM). Each ERM is a rack-mountable battery
module that extends the overall battery run time.
If you add an R5500 XR UPS to a modular cabinet in the field, you must change the
right PDU to be compatible with UPS.
