voltage: 12.3 to 12.5 VDC (12.4 VDC
nominal); Power: 72 watts,

minimum, 88% maximum
modem cable for connecting the
terminal to the card. Also be sure to
have a 10BASE-T connection from
your local LAN, a locally connected
workstation that you can use to
ping and HTTP into the card, and an
IP address for the card. In addition,
you’ll need the network’s space and
submask and the IP address for the
default gateway of your LAN.
Control Module
This Control Modules enable
you to daisychain up to eight
16-Port Managed MicroRACKs
and control them all.
With a Control Module installed
in each of the racks, you have total
control of up to 120 installed DSL
modem, line driver, or fiber modem
or CSU/DSU cards! What’s more,
you can manage the 120 remote
modem/line drivers as well.
Installed in the 16-Port
Managed MicroRACK, the module
is used to control the rack’s other
cards from an asynchronous
RS-232 terminal or a computer
running terminal emulation.
Supporting terminal data rates to
19.2 kbps, the Control Module has a
modular port for connection to the
RS-232 terminal, and a serial port for
daisychaining between racks.
When you want to reach or
configure a particular function card,
simply key in an addressable
command, which the Control
Module passes along to all the
function cards in the rack. The
appropriate card recognizes its
address and responds to the
command.
As with the 16-Port Managed
MicroRACK’s function cards, the
Control Module consists of a front
card and a rear card that meet in
the middle of the rack. The rear
card has two modular 10-pin RJ
jacks (labeled Port A1) for
connection to the RS-232 terminal.
If the Control Module is being used
in a daisychained application, the
module’s
Port B1
provides the link
to the next Control Module in the
chain.
Wiring a local Control Module
for a daisychain connection
requires the use of two straight-
through modular cables. One cable
connects the serial port of the
RS-232 terminal to Port A1 of the
chain’s first Control Module; and the
second connects Port B1 of the
chain’s first module to Port A1 of the
chain’s second module. You would
use the same cabling procedure to
connect the second module to a
third module, and so on if there are
additional modules in the chain.
