The rear panel of the Edge Switch includes the following:
• Power supplies
The Edge Switch contains two power supply assemblies with internal cooling fans. The
redundant, load-sharing power supply assemblies step down and rectify facility input power to
provide 3.3 volts direct current (VDC), 5 VDC, and 12 VDC to the CTP card. The power supplies
also provide input filtering, overvoltage protection, and overcurrent protection.
Either power supply can be replaced while the Edge Switch is operational. Each power supply
has a separate connection to the CTP card to allow for independent AC power sources. The
power supplies are input rated at 90 to 264 volts alternating current (VAC). Power supply
requirements are listed in
• Cooling fans
Four fans (each a separate FRU) provide cooling for the Edge Switch power supplies and the
CTP card, as well as redundancy for continued operation if a single fan fails. Each fan FRU can
be replaced while the Edge Switch is operating.
Maintenance port
•
The rear panel provides a 9-pin RS-232 maintenance port that provides a connection for a local
terminal or dial-in connection for a remote terminal. Although the port is typically used by
authorized maintenance personnel, operations personnel can use the port to configure Edge
Switch network addresses.
