2. Use a power cable with a C13 connector and a C14 connector to connect the controller’s left
power supply to the output receptacle on the same BPS power module to which you connected
the USB cable in the previous step (see callout 2 in Figure 2-4). Use the cable strain relief
strap on the power supply to secure the power cable to the controller chassis.
3. Using a power cable with a C13 connector and a connector that fits the receptacle of your
power source, connect the controller’s right power supply to a power source (callout 3 in
Figure 2-4). Use the cable strain relief strap on the power supply to secure the power cable to
the controller chassis.
For high availability, be sure the power source is not the same as the power source to which the
BPS power module is connected.
4. Repeat the three steps to connect the second controller to the other power module on the BPS.
Network Configuration Overview
The EqualLogic FS7500 requires three networks:
• Client network – Used for client access to the NFS exports and CIFS shares hosted by the
NAS service. For each controller, at a minimum, you need one client network connection. The
recommended configuration is four client network connections for each controller.
• SAN network – Used for access between the PS Series group (SAN) and the NAS nodes. For
each controller, at a minimum, you need one SAN network connection. The recommended
configuration is four SAN network connections for each controller.
• Internal network – Used for communication between the NAS nodes. For each controller,
you need a minimum of three internal network connections. The recommended configuration
is five internal network connections for each controller.
For security reasons, the internal network is usually a private network and the client network must
be separate from the SAN and from the internal network.
An FS7500 Controller has three four-port NICs, plus a single network interface port in the lower
left corner of the back panel. These ports are dedicated to specific networks:
• The ports in the two top NICs and the single port are only for SAN and internal network
connections.
• The ports in the bottom NIC are only for client network connections.
The FS7500 controller comes with an attached quick-reference tag that shows the cable
connections.
