Central Boards
3.2.11 IMODN
Introduction
The Integrated Modem Card New (IMODN - S30807-Q6932-X100) is an optional subboard for
HiPath 3000 central control boards.
It permits the use of remote service (analog mode up to 33.6 Kbps) over analog trunks without
an external modem.
IMODN is the compatible successor of IMODC. Functional differences between both modules
only exist in the higher transmission speed of the IMODN.
Loadable loadware
To avoid exchanging the IMODN subboard during a software upgrade, IMODN loadware is au-
tomatically updated in V4.0 SMR-08 and later.
Updating the IMODN loadware takes approx. 10 minutes beginning with the idle system status.
The red LED on the IMODN lights up repeatedly during the loading procedure. IMODN is ready
as soon as the green LED starts to flash.
If the IMODN loadware is not updated when the system is reset, the green LED starts to flash
approx. 10 seconds after the reset. The green LED continues to flash after the system boot.

Caution
Place the central control board on a flat surface before inserting the IMODN sub-
board.
The spacing bolts supplied guarantee the correct insertion of the subboard, so you
should always mount them (see Figure 3-6).
Otherwise you may damage the board.
