Rack Mount Installation. The M4.2Si chassis has four rack mounting holes in its chassis and has

been designed to fit in a 19” standard 1RU space. Plastic ‘finishing’ washers are recommended to

protect the painted finish around the mounting holes.

Power Connection. The AC power cable supplied with the M4.2Si must be connected from the

M4.2Si’s IEC320 power entry module to an AC mains outlet with a functional earth ground connection.

The M4.2Si has been set at the factory to operate at 120VAC unless otherwise specified on the

shipping carton. The M4.2Si export version is configured for 240VAC operation. Please connect your

M4.2Si to an uninterruptible power supply (UPS) to protect against power surges and

brownouts.
