Chapter 1 — MS27101A Installation
1-1 Introduction
The MS27101A remote spectrum monitor can be ordered with optional rack mounting
hardware that allows it to be mounted into a standard 48 cm equipment rack in either a
single unit installation or a side-by-side installation. Section 1-3 describes single unit rack
mounting, Section 1-4 describes side-by-side rack mounting.
The MS27101A must be installed by a trained service person who is familiar with RF system
integration and local regulatory and compliance requirements for the region in which the
instrument is being installed. Read the MS2710xA Product Information, Compliance, and
Safety Guide (PN: 10100-00064) for important safety, legal, and regulatory notices.

Connector Glands
The figure below illustrates the IP67 rated Ethernet (top) and power connector (bottom) gland
assemblies.
Power Supply
The MS27102A Remote Spectrum Monitor comes with an indoor AC/DC power converter with
a pre-assembled power cable and gland. This is to be used only for indoor applications. For
outdoor usage, a DC power supply must be supplied by the user and must meet the following
criteria:
• Voltage rating: 11 VDC to 24 VDC (supplied at instrument connector)
• Power dissipation: 11 W
• Environmental ratings: IP67 rating recommended or otherwise suitable outdoor
supply, including supply cabling
•Powercabling:appropriate weather resistant cabling with adequately sized
conductors for the length of run and power demand. The provided connector has screw
terminals and will work for wire sizes from 14 AWG to 18 AWG with an outside cable
diameter of 5.5 mm to 8.0 mm (0.22 to 0.31 in).
