INTRODUCTION Rack Mountable Chassis The MMAC-M5FNB chassis can be mounted into a standard 19" (48.26 cm) equipment rack. Separate rack mount brackets are included that allow the unit to be flush mounted or recessed 3" from the front plane of the rack mount unit for safety and ease of network connections.
37.6 cm (14.8 in.) deep and 37.6 cm (14.8 in.) high is needed for the MMAC-M5FNB enclosure. • If the MMAC-M5FNB is to be placed on a shelving unit, the shelf must be able to support 33.8 kg (75 lb.) of static weight.
10 C (18 F) per hour must not occur. 2.2 MMAC-M5FNB CONFIGURATION GUIDELINES The MMAC-M5FNB has four slots that accept media interface modules when the hub is configured with dual power supplies, and five MIM slots when the hub is configured with one power supply. (The slots are numbered from right to left;...

INSTALLATION REQUIREMENTS AND SPECIFICATIONS SAFETY Designed in accordance with UL1950, CSA C22.2 No. 950, IEC950, and EN60950. Meets the EMI requirement of FCC Part 15 Class A and EN55022 Class A. Meets the immunity requirements of EN50082-1. This unit must be assembled and used in accordance with the instructions in this manual.
Save the shipping box and materials in the event the MMAC-M5FNB has to be reshipped. 2. Slide the two foam end caps off the MMAC-M5FNB, and remove the unit from the protective plastic bag. Set the MMAC-M5FNB aside in a safe place.
1. Using a Phillips head screwdriver, remove the eight screws (item 1, Figure 3-1, following page) – four on each side of the MMAC-M5FNB – which are closest to the front of the chassis, and set them aside. 2. The rack mount brackets (item 2) provided have two sets of holes: use the front holes (item 3) to mount the chassis flush with the equipment rack;...

Figure 3-1. Installing the M5FNB into a Rack 3. Insert the screws through the holes on the mounting bracket and into the screw holes on the MMAC-M5FNB. 4. Tighten the screws until the mounting bracket is securely attached to the unit.
9. Tighten the nuts and bolts until the unit is secured to the rack. 3.2.2 Rack Mounting the Cable Tie Tray A cable tie tray is provided with the MMAC-M5FNB to support and organize cables connected to the unit. The tray is designed to be installed under the MMAC-M5FNB in the equipment rack.
Figure 3-2. Cable Tie Tray Installation 3.2.3 Inserting the Fan Tray The MMAC-M5FNB is equipped with a removable fan tray that allows for easy periodic cleaning and/or replacement if a problem occurs with fan operation. To insert the fan tray in the MMAC-M5FNB: 1.
MMAC-M5FNB SETUP 4. When the MMAC-M5FNB is ready to be turned on, observe the LED on the front of the fan tray. This LED should be red for a moment after you turn on the power switch, and then change to green to indicate that all the fans are operating properly.

Note: The power requirements of some FDDI configurations require dual power supplies. The MMAC-M5FNB power supply modules must be installed in the rightmost and leftmost slots of the chassis (Figure 3-4). If you intend to install a single MMAC-M5PSM, install it in the rightmost slot; the far left slot is then available for an optional fifth MIM.

M5PSM. (Note: There are no panels over the rightmost M5PSM opening.) 4. Slide the M5PSM into the appropriate slot of the MMAC-M5FNB (Figure 3-5) as follows: a. Hold the module by placing one hand on the handle located on the front panel and using the other hand to support the body of the module.
6. If you are installing an additional M5PSM, repeat steps 3 - 5. After you have finished installing the power supply module(s), the MMAC-M5FNB is ready to be powered up; however, we recommend that you first install the repeater/management module and the MIM or MIMs, as well as the security bars (if desired).
