IP-DSU
.

3.1 Equipment
Unpack and inspect the
IP-DSU
units and other components, and have on hand a #2
phillips and medium-sized flathead screwdriver.
3.1.1 Stand-alone IP-DSU Equipment
For stand-alone
IP-DSU
installations, the following items are needed.
A minimum of two
IP-DSU
units.
For AC operation, a power supply for each
IP-DSU
(DC is directly wired into the unit).
A V.35 or DB25 (RS-232-C) cable for each connection between an
IP-DSU
and a BNS
trunk I/O board. (V.35 requires a DB25 to V.35 adapter)
An RJ45-terminated twisted-pair data (RS232-C) cable for each connection between the
IP-DSU
console port and an asynchronous device.
A category 5 RJ45-terminated twisted-pair data cable for each connection between the
IP-DSU
and the local 10BaseT LAN hub or router.
10BaseT LAN hubs or routers with 10BaseT access to the Intranet or Internet.
For DC operation, a strain-relief clamp for wire stabilization
3.1.2 Rack-mount IP-DSU Equipment
When installing
IP-DSU
units in a rack-mount configuration, it is necessary to gather the
items listed above for stand-alone
IP-DSU
installation, plus the following equipment.
An EIA-standard 19-inch or 23-inch equipment rack with internal, vertical mounting rails.
Hole spacing on the vertical mounting rail may be 1 inch, 1.75 inch or 2 inch. Use the
dimension specifications in the appendix to calculate how high the rack needs to be to
support a specified number of rack-mount panels. For example, seven rack-mount
panels measuring 10.5 inches each will fit in a data equipment rack with internal

Cabling configurations, describing proper cabling between the
IP-DSU
device interface (V.35/RS-232C)
and BNS I/O boards is available in the
Data Networking Products Cabling Guide.
