l In Figure 1-29, the filled holes are for floating nuts to fasten subracks.
l The EPS75-4815A power supply provides only two 40 A inputs. Therefore, only one power board is
allowed in each of the two ETSI subracks.
l In the range of 90 V AC to 175 V AC, the output current of the EPS75-4815AF power system decreases
linearly, limited within a specified range. In areas with 110 V power supply, dual-live-wire input is
recommended. When 110 V single-live-wire input is used, the output power of the EPS75-4815AF
power system reduces to half (maximum: 1600 W) of that in 220 V. In this case, only one subrack is
allowed in the cabinet.
l When high-density boards are configured, cables in some areas are close to the air exhaust vents of the
ETSI subrack. In this case, to ensure smooth ventilation, no cabling is allowed at least 1 U space around
the air exhaust vents.
l Cabinet installation against the wall or back-to-back cabinet installation is not supported.
