Chapter 11 Switched ePDU Advanced Features
This chapter explains the following advanced features of the Switched ePDU:
S Strapping (connecting Switched ePDUs together)
S Advanced boot configuration
S Contact sensor wiring
S Recovering from a lost password
Strapping
Strapping is an advanced feature of the Switched ePDU that enables you to connect
up to 24 Switched ePDUs together under one common network address using
RS-485 serial communication. Strapping allows for control of up to 576 outlets
through one interface.
The strapping feature applies to Switched ePDU models that have four RJ-45 ports on
the face, two of which are marked “Strapping” (see Figure 28). Up to 24 Switched
ePDUs can be strapped together using lengths of straight-through Ethernet cable
(rated Category 5, 5e, or 6) with RJ-45 connectors on both ends. One Switched ePDU
is designated the primary (master)Switched ePDU, and all the other secondary (slave)
ePDUs are accessible through the primary's serial, Telnet, or Web interface. Strapping
is useful in situations where IP addresses are limited or where all Switched ePDUs
need to be controlled from one serial interface.

Figure 28. Strapping Ports (Typical)
After initiating a strapping connection to a secondary (slave) Switched ePDU, all of the
primary (master) Switched ePDU's serial, Telnet, and Web interface pages change to
present the secondary Switched ePDU's state and configuration. From the interface it
is easy to view the secondary Switched ePDU's outlet status, control an outlet or
group of outlets, schedule outlet events, view the Power Log, and check sensor or
switch closure status.
