DC Power Module
The DC power module is a single-slot module designed for the RM16M DCV-R Data Shelf.
The RM16M DCV-R Data Shelf can hold up to two DC power modules. When two DC power
supply modules are used, any loss of supply or operating voltage to one module causes the other
module to carry the entire load. If this happens, the common alarm contacts close to reflect the
alarm condition.
The DC power module consists of:
•
A DC-to-DC switching regulator
•
A green Power light on the front panel
•
An interface connector on the back of the module
•
Cooling fan
Installing Power Modules
The following procedures describe how to install power modules. This procedure should only be
performed by personnel familiar with this procedure.
1.
Lower the Data Shelf’s hinged front panel.
2.
Locate the power module slots between slots 8 and 9.
3.
Grasp power module handle with one hand while supporting the bottom of the module with
your other hand.
4.
Align the module in the Data Shelf guide grooves.
5.
Gently slide the module into the Data Shelf until it rests against the edge connector.
6.
Firmly push the module in to seat the edge connector.
7.
To install a second power module, repeat steps 2 through 5, selecting the adjacent power
module slot in step 2.
8.
Close the front panel.
9.
When you finish, connect a power source to the module.
AC Module: Connect a power cord to AC plug on rear of power module. Then plug
power cord into a 115 or 230 VAC outlet, as required.
Redundant AC Modules: Connect both power cords to port 1 and 2.
Redundant DC Modules: Attach a DC power source as described under the “DC
