4.1.2 Restrictions
Observe the following restrictions on the installation of optical shared hub units.
• The optical shared hub unit may be used by natural cooling. If it is installed in an
enclosed cabinet, for example, install a fan or other means of cooling to prevent the
inside temperature from rising too high. The working temperature range is 0 to 50
o
C,
but because a power unit is also installed, it is recommended that the temperature be
kept low to extend product life.
• The maximum length of the cable connecting the master hub unit UTNH23A for line A
to the master hub unit UTNH23B for line B is 3 m. In cases where these units for lines
A and B are installed apart from each other, keep the cable within the specified length.
• In principle, install the hub unit UTNH23A for line A and the hub unit UTNH23B for line
B in the same cubicle.
• In case of installing the hub unit UTNH23A for line A and the hub unit UTNH23B for
line B in separate cubicles, attach shielded cables and ferrite cores to them instead of
using the lines A and B connecting cables provided as accessories.
• In installing master hub units for lines A and B one upon another, keep a space of at
least 5 cm from one hub unit to another.
Figure 4-2 Stacking Optical Shared Hub Units
• The maximum steps of cascade connection to hub units is 5.
When use a twisted pair cable to connection, count 1 step.
