Appliance User Guide  
Published: November 4, 2011  
This document contains brief, concise instructions that tell you how to install the MCS 7890-C1 quickly.  
This document includes the following topics:  
Before You Begin  
The Cisco MCS 7890-C1 is an easy-to-manage, purpose-built appliance that integrates the benefits of  
media processing (for voice calling and mobility) and digital circuit gateway functionality on a single  
system. Consolidating these functions creates a cost-effective solution that is simple to set up, manage,  
and use, thereby lowering total cost of ownership and providing a smooth migration from older, outdated  
telephony systems to IP communications.  
Designed for midmarket organizations with smaller IT staffs, the solution provides investment protection  
with the capacity to grow to up to 300 employees (400 endpoints) and ten total sites (nine remote sites).  
The Cisco MCS 7890-C1 comes preinstalled with the Cisco Business Edition 3000 software, integrated  
dual T1/E1 public-switched-telephone-network (PSTN) interfaces, and an easy-to-use administration  
and provisioning interface.  
Cisco supplies the MCS 7890-C1 in a single package that contains the items that are listed in the  
Unpacking the MCS 7890-C1 section. Make sure all of the parts are in the package. Never use defective  
parts. Never replace a part that is listed in the Unpacking the MCS 7890-C1 section with a different type  
of part. If any item that is listed in the Unpacking the MCS 7890-C1 section is damaged or missing,  
contact your Cisco representative at your earliest convenience.

Mounting the MCS 7890-C1  
This section includes the following MCS 7890-C1 topics:  
Rack-Mounting  
Perform the following procedure to mount the MCS 7890-C1 in a 19-inch rack. You use items from the  
rack-mounting kit described in Table 2 on page 3.  
Procedure  
Step 1  
Use screws to attach the rack-mount brackets to the left and right sides of the MCS 7890-C1 as Figure 2  
on page 4 shows.

Mounting the MCS 7890-C1  
Step 2  
On the brackets you attached in Step 1, choose which pairs of holes you want to use. As Figure 3 shows,  
you can choose either top holes (Type 1) or bottom holes (Type 2). Use Type 1 holes if you want to align  
the MCS 7890-C1 under the bottom of other equipment in the rack. Use Type 2 holes if you want to align  
the MCS 7890-C1 over the top of other equipment in the rack.

Connecting the MCS 7890-C1  
Wall-Mounting  
Perform the following procedure to mount the MCS 7890-C1. You use items from the wall-mounting kit  
described in Table 3 on page 3.  
Procedure  
Step 1  
Step 2  
Take the wall-mounting template and temporarily attach it to the wall on which you want to mount the  
MCS 7890-C1. Attach the template to the wall so that the image of the MCS 7890-C1 appears in the  
exact place where you want to mount the MCS 7890-C1.  
Locate the four dark circles on the wall-mounting template. Locate the lines that intersect inside these  
dark circles. At each point where the lines intersect inside these dark circles, use a scratch awl or other  
sharp pointed object to punch a hole through the wall-mounting template to mark the spot on the wall  
where you want to drill a hole for a mounting screw.  
Step 3  
Remove the wall-mounting template from the wall. At each of the four spots you marked in Step 2, drill  
a hole with a 0.3-inch-diameter (7.5-mm-diameter) drill bit. Drill each hole at least 1.37 in. (35 mm)  
deep.  
Step 4  
Step 5  
Step 6  
Into each hole that you drilled in Step 3, insert a plastic anchor so that the opening of the anchor is flush  
with the wall surface.  
Into each plastic anchor that you inserted in Step 4, insert a tapping screw. Screw in the tapping screw  
so that there is 0.09 inches (1.5 mm) of space between the wall and the back of the screw head.  
Hang the MCS 7890-C1 on the wall. To do this, perform the following procedure:  
a. Hold the MCS 7890-C1 in both of your hands with the Cisco logo facing you and the MCS 7890-C1
