MOUNTING AND POWER CONNECTIONS
The 5700MSC chassis holds the main board, one power supply, and one fan module. Dual power
supplies are an available option in which case a second power supply replaces the fan module. The
chassis has built-in rack mounting ears and fits in a standard 19” rack. Two fans on each side cool the
unit. Clearance of 2” (5cm) must be maintained around the fan exhausts on either side of the chassis.
The power supply operates from an AC line frequency of 50Hz to 60Hz, at 100V-240V (auto-sensing).
The fan module does not require AC power to function. The power consumption of a 5700MSC is 125
Watts with all options installed.
If dual power supplies are fitted, they should both be supplied with AC power. Each power supply has
its own IEC C14 AC power inlet. The inlets are isolated from each other and can be powered by the
same AC power source but ideally should be powered from different AC sources for true redundancy.
If both supplies are not powered, the unpowered supply will trigger a system fault. A redundant power
supply may be added at any time to a unit by removing the fan module and installing the second power
supply.
The power supplies and fan module are hot swappable and accessed from the front of the unit by
removing the front panel. Each power supply and fan module has a Phillips mounting screw at the
front that can be used to secure the module in order to prevent accidental removal.

FRONT PANEL INSTALLATION
The 5700MSC comes with a removable front panel that is equipped with two color LCD screens, along
with 10 pushbuttons, and a control knob for navigating the menu system and configuring the unit. The
front panel is secured by the two thumbscrews on either end. The front panel can be removed and re-
installed while the unit is running to provide access to the power supplies and for troubleshooting
purposes. When re-installing the front panel be sure to fully tighten the thumb screws.
When AC power is applied to the 5700MSC and the power supplies are switched on, the unit will start
up automatically. The front panel should become operative within approximately 30 seconds.
