INSTALLATION

This chapter outlines MicroMMAC-T installation and network connection procedures. Be sure that the network meets the guidelines and requirements outlined in Chapter 2, Requirements/Speciﬁcations, before installing the MicroMMAC-T.

3.1 UNPACKING THE MicroMMAC-T

Unpack the module carefully. Preserve and save all packaging materials for possible storage or transport of the MicroMMAC-T.

Thoroughly inspect the MicroMMAC-T immediately. If there are any signs of damage to the module, contact Cabletron Systems Technical Support immediately.

3.2 ATTACHING THE STRAIN RELIEF BRACKET

Attach the strain relief bracket to the front of the MicroMMAC-T as described:

1.From the MicroMMAC-T installation kit, locate the strain relief bracket (shown in Figure 3-1) and four 8-32 x 3/8” screws.

CAUTION: Use of longer screws may cause damage to the unit or electrical shock.

2.Attach the strain relief bracket to the bottom of the MicroMMAC-T as shown in Figure 3-1.
