cient to power a fully loaded chassis.
The F-MB21B-R chassis is designed to tolerate the following without loss of installed card functionality:
•The loss of one AC supply (120/240V) source.
Since there are two power inlets on the F-MB21B-R chassis, the cards in the chassis can operate with only one
powered; however, the chassis would not be fully redundant.
•The loss of one or two PSUs of the four PSUs in the F-MB21B-R chassis in any combination.
The following replacement part is available for the power supply (#P-MB21B-PS).

MB21 Installation
The MB21 may be installed in one of two ways: (1) free-standing on a desktop or rack shelf, or (2) fastened directly
to a rack using support brackets (supplied).
WARNING To prevent electric shock, do not remove the cover of the MB21 chassis. There are no user-
serviceable parts inside. The MB21 chassis is to be installed and serviced by qualified personnel only.
To install the MB21:
1. Unpack the box and visually inspect the package contents for any evidence of shipping damage. See the
Important Notice document in the box for a list of contents.
2. In addition to the contents of the MB21 box, you may need to have the following items available:
•5/16 hex nut driver
• Screwdriver with Phillips #1 and #2 bits
• Right-angle ratchet screwdriver or Allen key (for rack screws)
• 8 x rack screws
3. Place the MB21 on a solid surface.
CAUTION The MB21 should always be moved or lifted by two persons. The handles on the front of the
chassis should be used for a solid grip.
4. Using a 5/16 hex nut driver, remove the hex head screws –(E) and (F) in Figure 13 below – holding the
support brackets in place. Remove the support brackets.
5. If the MB21 is to be installed on a desktop or rack shelf, screw the rubber footpads into the base of the
chassis. Move it to the desired location, and then skip ahead to step #11. Otherwise, continue to step #6.
6. Position the empty MB21 in the rack at the desired location.
TIP If space allows, put two screws into the rack posts just below the bottom of the MB21, and then rest
the MB21 on those screws using the alignment notches at the bottom of the chassis mounting flanges.
This will line up the screw holes on the MB21 flanges with the corresponding holes in the rack posts.
7. Using a right-angle ratchet screwdriver or Allen key, secure the front chassis mounting flanges to the rack
(see red arrows in figure below; screws not provided).
NOTE If necessary, you may remove the handles on the front of the chassis by using a Phillips #2 screw-
driver to unscrew the four handle screws (see blue arrows in Figure 13 following).

8. Loosely fasten the support brackets to the sides of the chassis with hex nut screws at (E) and (F). Slide them
into place and secure them to the back of the rack (see red arrows in figure above; screws not provided).
NOTE If you need to further extend the support brackets, you may safely remove the two screws at po-
sition (E) on each side.
9. Using a 5/16 hex nut driver, tighten the four screws at position (F) on each support bracket.
10. If needed, tighten the two screws at position (E) on each support bracket.
11. Using a Phillips #1 screwdriver, remove slot covers (D) as required.
CAUTION Failure to properly secure or support the MB21 as described above may result in serious
damage to the enclosure and/or its contents.
12. (F-MB21X-R only) If using a system interface, insert it now. The mating connector is provided but you will
need to add your own wiring.
13. Insert the cards from the front (as shown in Figure 10 on page 16).

To power up the MB21 Chassis:
1. Turn all two or four PSU Power On/Off switches to the ON (1) position.
2. Connect the power cords to both power receptacles.
3. Plug both cords into earthed AC power sources.
TIP To ensure redundancy, each power input should be connected to a different 120/240V circuit and be
isolated.
The PSU Status LED will turn green indicating that the chassis is powered up (only if both or all four Power
On/Off switches are On).
In the front of the chassis, the Status LEDs will start blinking green, indicating that the encoders/decod-
ers/gateways are booting up.
4. Wait until the Status LEDs stay solid green, indicating that the chassis is ready for operation.
CAUTION The power supply cords are used as the main disconnect devices on the MB21 chassis. There-
fore, ensure that the socket-outlet is located/installed near the equipment and is easily accessible.
The MB21 chassis has more than one power supply cord. Be sure to disconnect both (2) power supply
cords before servicing to avoid electric shock.
To begin configuring the unit, open the Web interface and log in. Please refer to the product documentation for
details.
