D-Link DXS-3610-54S, Quick Installation Manual

Page: 11 / 38

A second DC PSU module can be installed into the second PSU module slot labelled PSU-2 . If the primary
DC PSU fails, the second DC PSU is used to provide DC power to the Switch. This takes place immediately
and automatically.
When the DC PSU module is securely installed, insert the one end of the DC power cord, with the plug, into
the matching DC power socket on the DC PSU module and the other end of the DC power cord to the DC
power source (-48VDC/5.2A). Make sure that the connection polarity (positive and negative) is correct to
avoid any damaged.
Figure 17. Connecting a DC Battery to the DC Power Supply Module
There is no power switch/button on the Switch. The Switch will power on automatically.
CAUTION : Before connecting the DC power cable to the DC power input socket, on the
switch, the DC power cable must be properly connected to DC source, at your facility,
by a qualified, licensed electrician.
Installing Fan Modules into the Fan Module Slots
This section guides the user through installing fan modules into the fan module slots. On the rear panel of
the DGS-3610-54S switch, there are five fan module slots. Front-to-Back (FB) or Back-to-Front (BF) fan
modules can be installed in these slots. By default, the Switch is shipped with five
DXS-FAN200 modules
pre-installed.
NOTE: The fan modules support a specific airflow direction. This airflow direction must
be the same as the PSU module(s) installed. The default airflow direction is front-to-
back on all the installed PSU modules and fan modules.
