Basic Hardware Features

The unit can be fitted into a standard 19” rack or as a desktop and is 2.6” (1.5U high). For rack mounting, the unit is simply screwed to the sides of the rack with 2 x 2 bolts.

A standard configuration will include two LIMs. To insert or extract a module into its slot, grip the two mounting screws on the front panel and push to insert, or pull to extract. A network-side LIM should be installed in the middle slot. The user-side LIM should be installed in the left side slot. The third module, a hot standby module is placed in the far-right slot.

Power Supply and Fuses

The unit can be powered with 110/220VAC. A -48VDC option is also available. The system is protected the following:

• For 220V products, the system is protected with a 1.25A slow-blow fuse (F1).

• For 110V products, the system is protected with a 2.5A slow-blow fuse (F1).

• The optional -48V power supply is protected with a 3.15A slow-blow fuse.

• Fuses are located in fuse holder (FH1).

Cable Connections

Caution All modules are susceptible to electrostatic discharge (ESD) even while installed. Take the

necessary precautions to minimize electrostatic damage while handling modules.

Connecting Optical Cables

Warning

Step 1 Prepare a pair of appropriate (multimode or singlemode) optical cables with appropriate (SC or ST)

Step 2 Snap the cables into the LIM ports on the front panel of your Cisco 8110 unit.

When LIM-155SM-I ,LIM-155SM-L, LIM-155SM-XL, , LIM-155SM-I-SH, LIM-155SM-L-SH or LIM-155SM-XL-SH are used the CISCO 8110 is a Class 1 Laser Product

Take the necessary precautions to avoid dangerous radiation hazards if these modules are not handled properly.

To connect your Cisco 8110 unit optical interfaces:

connectors on the Cisco 8110 side.

• It is advisable to mark the ends of the cable so that you can identify the wires.

• Remove the optical connector protective cover.

Connecting Electrical Signal Cables

To connect your Cisco 8110 unit electrical interfaces:

Step 1 Prepare a pair of appropriate cables with connectors on the Cisco 8110 side

It is advisable to mark the ends of the cable so that you can identify the wires.

Step 2 Attach the cables into the LIM ports on the front panel of your Cisco 8110 unit. Step 3 Attach the other end of the cable into the ATM switch or other ATM equipment. Ensure that each cable

connects to Tx on one end and Rx on the other.

Connecting the Terminal

Basic Hardware Features

Basic configuration of your Cisco 8110 unit can be performed in one of two ways: either by using a standard ASCII terminal, or using the in-band management software application.

To connect an ASCII terminal to the Cisco 8110 terminal port:

Step 1 Configure the terminal: 9600 baud, 8 data bits, 1 stop bit, no parity, xon/xoff flow control. Step 2 Plug the included console cable into the terminal port located at the back of the Cisco 8110 unit (CIT).

(See Figure 3-1).

Step 3 Connect the other end of the cable to the terminal.

Note Refer to Configuration in Chapter 4 for information on using the console management

software for basic configuration.

To connect the terminal using the in-band management software application, see the“Installing a Line Interface / Compact Subscriber Module (LIM)” section on page 3-4.

Installing a Line Interface / Compact Subscriber Module (LIM)

To install a LIM in your Cisco 8110:

Step 1 Make sure that the LIM module state is OOS (Out Of Service) using the console, or the in-band

management application.

Step 2 Place the module’s card edges into the right and left module guides at the front of the

Cisco 8110

Step 3 Slide in the module until it makes contact with the backplane, then push firmly to mate the connectors

solidly with the backplane.

Step 4 When the module is seated solidly against the backplane, secure the module’s front panel to the Cisco

8110 chassis using the mounting screws on the right and left of the module’s front panel.

Step 5 Securely install and fasten each module to facilitate the installation of the one next to it. Step 6 Configure the module type to the actual LIM type, using the console or the in-band management

application.

Step 7 Change the module state to Active, using the console or the in-band management application.
