EdgeAccess Universal Chassis System
Chapter 1
Overview
The 2346 Managed T3 Fiber Optic Modem converts and extends T3/DS3 signals between devices
located up to 100 Km apart. Use the modem to extend a PBX, router, video codec, M13 multiplexer,
or ATM switch. The 2346 receives and transmits 44.736 Mbps data on single mode or multimode
fiber optic cable.
The 2346 front panel, shown in Figure 1, includes:
• Electrical and optical connectors
• Reset switch
• LEDs for:
• System status
• Configuration
• Electrical signal
• Optical signal
Figure 1. The 2346 Front Panel
The 2346 can be used in a variety of chassis. To install a 2346 in a UCS 1000 or UCS 1001 chassis,
you must use a Model 1230 Bus Access Module (BAM); however, you can install a 2346 directly in a
UCS 1002 or standalone enclosure.
• The UCS 1000 Chassis can hold up to 15 model 1230 BAMs with up to two 2346 modems per
BAM. This allows a total of 30 2346 modems per UCS 1000.
• The UCS 1001 Chassis can hold up to two model 1230 BAMs with up to two 2346 modems per
BAM. This allows a total of four 2346 modems per UCS 1001.
• The UCS 1002 Chassis directly hosts up to fourteen 2346 modems, or thirteen 2346 modems with
the optional Domain Management Module (DMM) installed.
• Each standalone enclosure, such as a Model 1020 or 1030E, holds one 2346 modem.
The 2346 is hot swappable; you can insert or remove it at any time without disrupting the data
transfer of other modules in the chassis.

Hardware Installation and Functions
Before setting up the 2346, make sure the chassis or enclosure is installed and its User Manual is
available for reference. If the system includes an optional DMM and CIM(s), make sure these are
available:
• Serial cable (required to connect to a VT100 type terminal or PC)
• VT100 type terminal or PC to run the User Interface Manager software
• The DMM and CIM manuals
Set Up and Installation
Unpack and inspect all components. Save the shipping carton and packing materials in case you need
to return the equipment to the manufacturer. Appendix A provides information for Return Material
Authorization (RMA).
1. Before inserting the 2346, check the front panel to verify that the 2346 provides the wavelength
that matches its link partner; see Figure 1.
2. Set SW2-1 and 2-2; see Figure 2.
• SW2-1, Line Buildout (LBO): Off (default) for Short LBO, <225 ft (68 m), or On for Long
LBO, >225 ft; when software control is enabled at the Functional Configuration screen,
SW2-1 is ignored.
• SW2-2, Software override: Off (default) is software, On is hardware; set to Hardware in
unmanaged environment, only. For installation in a managed environment where you plan to
use software control (see page 3-11), set SW 2-2 to Off.
Note: If the 2346 was previously installed in a managed environment and set in the User Interface
to software control, follow these steps to set it to hardware control when installing it in an
unmanaged environment:
a. Set SW2-2 to On.
b. Insert the 2346 in a slot with the power on, then remove it.
c. Set SW2-2 to Off.
d. Insert the 2346 in a slot with the power on, then remove it.
e. Set SW2-2 as needed.
3. Set jumper W10 as needed for normal (to NP) or wide pulse (to WP); see Figure 2. NP is the
default.

4. To install a 2346 in a UCS 1000 or 1001 chassis, you must use a Model 1230 BAM; each BAM
can hold up to two 2346 modems. Follow these steps to install the BAM and the 2346:
a. Insert a BAM into an available slot in a UCS 1000 or 1001. Slide the BAM into the rails and
push it firmly into the backplane, then tighten the captive screws. If you encounter
resistance, check that no connector pins are bent.
b. Insert a 2346 into an unused slot in the BAM. Slide the 2346 into the rails and push it firmly
into the backplane, then tighten the captive screw. If you encounter resistance, check that no
connector pins are bent.
5. To install a 2346 directly in a UCS 1002 or standalone enclosure, insert the 2346 into an unused
slot. Slide the 2346 into the rails and push it firmly into the backplane, then tighten the captive
screw. If you encounter resistance, check that no connector pins are bent.
If you encounter more difficulty, contact Canoga Perkins at (818) 718-6300 for technical assistance.
Note: The BAM and 2346 are hot-swappable and can be inserted or removed without disrupting
data transfer in other application modules.
6. If the 2346 is in a standalone enclosure, set the switch on the enclosure for loopback to Normal.
The 2346 uses electrical cables to connect to the local site and fiber optic cables to connect to the
remote modem. Follow these steps to connect the electrical and optical cables:
7. To connect to the local site, plug the BNC cables from the local equipment into the Rx and Tx
connectors using Tx to Rx, and Rx to Tx orientation.
Dirty optical connectors are a common source of link loss or attenuation problems, especially for
single mode fiber (SMF). Clean the connectors before plugging in a cable and whenever there is a
significant or unexplained light loss. To prevent contamination, always install protective dust covers
on unused fiber optic connectors.
8. Wipe the ferrule and the end-face surface of the male fiber coupler with a lint-free isopropyl
alcohol pad from a fiber cleaning kit.
9. Use canned air to blow out any dust from the female fiber coupler.

EdgeAccess Universal Chassis System
Caution: To avoid damaging the fiber end-surface or connector, use extreme care when
installing or removing cables.
10. Plug in the optical cables:
• If you have a simplex optical connector, use a single strand, single mode fiber cable between
a pair of 2346 modems, one at 1310 nm wavelength and the other at 1550 nm wavelength.
• If you have a duplex connector, use Tx to Rx, and Rx to Tx orientation.
11. Label each cable and connector with a signal name and direction.
12. For cable connections to other modules in the chassis, see the appropriate user manual for details.
13. Measure and record fiber link attenuation and transmission power before starting normal link
traffic in order to identify potential problems with links near the lower limit of receiver
limitations. For details on link attenuation and transmission power, see Chapter 4.
Power Up and Front Panel Functions
During the initial power-up sequence, all LEDs light amber. When start-up is complete and data is
transmitting normally across the link, the STA LED lights green and the CFG/TST, LOS, and CLS
LEDs are off. During normal operation, the LED colors change according to system and port
conditions. The STA and CFG/TST LEDs show the module condition. The LOS and CLS LEDs
show the electrical and optical signal conditions. Table 3 shows the LED states for various
conditions.

Alarm Functions
The 2346 can generate Major and Minor Alarms.
• UCS 1000 and 1001: a BAM is required and holds up to two 2346 modems. On the BAM, the
Status (STA) LED lights green if either 2346 is operating normally. If both modems have errors,
the BAM STA LED lights amber.
• UCS 1001: the alarm outputs are forwarded to the chassis motherboard.
• UCS 1000 and 1002: the alarms are forwarded over the backplane to the CIM and appear on the
Major (MAJ) and Minor (MIN) CIM LEDs and then are forwarded to the DMM for monitoring
and transfer to the Network Manager as traps.
• Model 1020 enclosure: the alarm information is forwarded to the management session.
• Model 1030 enclosure: alarms are not supported.
For details about setting up the Alarms, see Chapter 3; for viewing the Alarm Log, see Chapter 4.
