Location And Mounting - Keysight Technologies S9100A Startup Manual

2. 9 Location and Mounting

Consider ergonomics when locating any keyboard or mouse which will be used in
connection with an instrument.
Install the Keysight S9100A Base System and E7770A CIU so that the detachable
power cords are readily identifiable and is easily reached by the operator. The
detachable power cord is the disconnecting device. It disconnects the Mains circuits
from the Mains supply before other parts of the Keysight S9100A Base System or
E7770A CIU. (The front panel switches are only standby switches and are not LINE
switches.) Alternatively, externally installed switches or circuit breakers (which are
readily identifiable and is easily reached by the operator) may be used as
disconnecting devices.
The M1740A mmWave Transceiver does not have an AC power connection. It is
powered by a DC voltage from the E7770A CIU; this voltage is supplied over the
RF Cable Assembly to the LO/Pwr/Ctrl/IF In connector. The DC supply does not
represent a risk of personal injury.
S9100A 5G Multi-Band Vector Transceiver, Startup Guide
The Keysight S9100A Base System requires a 1U space below
when rack mounting.
The RF Cable Assembly should not be connected to, or
disconnected from, the M1740A mmWave Transceiver while it is
suppling DC power from the E7770A CIU. This connection should
be made only when the E7770A is powered off, or the cable is not
connected to the E7770A.
If the LED status indicator on the front of the M1740A is lit, this
indicates that it is powered up and the cable should not be
disconnected.
