16-PORT MANAGED M
Install up to 16 interface cards in only 2U of rack
space—and manage them via SNMP/HTTP!
W hen space is tight, choose the
BLACK BOX ® 16-Port Managed
MicroRACK system. Resilient dual-
power supplies and the ability to
mix different types of access
solution cards add up to a compact,
reliable solution—all in only 2U
(3.5") of vertical space in a 19" rack!
Two sturdy front handles allow
the rack to be installed, extracted,
or transported easily. Plus, it's
expandable; you can cascade
multiple racks and establish up to
320 card connections.
The 16-Port Managed
MicroRACK can not only save you
space and effort, but it also has
slots for a pair of power supplies
that provide redundant power to
keep your mission-critical
applications alive. Each power
supply is capable of providing 100%
of your rack power requirements.
In the event of a power failure, the
other supply immediately takes
over and the MicroRACK alerts you
to the failure. The rack also notifies
the central site operator of the
power failure through the network
management system.
RACK
ICRO
There are two types of rack
power supplies. The AC version
(PS466A) plugs into any standard
AC outlet (90–264 VAC, 50/60 Hz);
the rack comes with one of these
already installed. The DC supply
(PS466A-DC) can be attached to a
site's -48-VDC power (actual
voltage range can be from -42 to
-60 VDC). Each of these power
supplies—as do all of the function
cards designed for the
MicroRACK—consists of a front-
mounted "front card" and a rear-
mounted "rear card"; these cards
meet at a midplane interface inside
the rack.
A Managed MicroRACK can
take any combination of the power
supplies. A single supply provides
power to up to 16 rack cards. With
a pair of power supplies, you can
provide redundant power for up to
14 rack cards. This way, you can
keep your system operating
smoothly; it won't come to a
standstill if one supply fails.
Once powered, the rack begins
operating automatically—it has no
on/off switch—and you can check
the status of the power supply via
front-card LEDs.
There are five possible
configurations for the rack:
• Standard—16 cards and
1 power supply;
• Managed—15 cards,
1 SNMP/HTTP Card, and
1 power supply;
• Redundant—14 cards and
2 power supplies;
• Managed/redundant—13
cards, 1 SNMP/HTTP Card,
and 2 power supplies;
• Daisychained/redundant (up to
8 racks)— 13 cards, 1 SNMP/
HTTP Card, or 1 Control
Module, and 2 power supplies.
A wide variety of function
cards are available. You may also
want an SNMP/HTTP network
management module, which
enables you to configure and
perform diagnostics using SNMP
or HTTP over a 10BASE-T Ethernet
connection. If you want to
daisychain racks together, order
the Control Module (RM262C).
