EdgeAccess Universal Chassis System Chapter 2 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.
EdgeAccess® Universal Chassis System W10 SW2 Figure 2. Switch and Jumper Locations 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.
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.
EdgeAccess® Universal Chassis System 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.
EdgeAccess Universal Chassis System Chapter 3 Software Management You can manage the 2346 through VT100 Terminal Emulation, which is accessible by a Telnet session, HyperTerminal or similar terminal emulation software, a standard SNMP network manager, and CanogaView. If the 2346 is in UCS 1000 or 1002 with a CIM within a domain that includes a DMM, you can access the 2346 through the DMM.
EdgeAccess® Universal Chassis System 5. At the COM Properties dialog, on the Port Settings tab, check for these selections: • • • • • Bits per second: 19200 bps Data bits: 8 Parity: None Stop bits: 1 Flow control: None 6. `Click OK. HyperTerminal connects to the system and the VT100 terminal emulation starts. Management User Interface The Management User Interface for the 2346 provides screens for setup, monitoring, and diagnostics.
EdgeAccess Universal Chassis System Use these keys to navigate the screens: • • • • Space bar When a menu item is highlighted, press to cycle through all options for that item. Tab Press to move the highlight to the next column to the right. Enter Press to select the highlighted option for a menu item.
EdgeAccess® Universal Chassis System • To reach the 2346 directly, follow these steps: a. Type 4, "Manage or access a specific Module," and press . b. Type the slot and chassis numbers with a slash, such as "1/4" for chassis 1, slot 4, and then press . c. At the Module Menu, type 4, "Access User Interface," then press to reach the Main Menu screen for the 2346. • To reach the chassis, and then select the 2346, follow these steps: a.

To return to the System Configuration menu, press .
EdgeAccess Universal Chassis System 2. At the Alarm Output Configuration screen, type the number for an alarm and press . See Table 5. 3. Press to cycle to Enabled or Disabled and press . 4. To return to the Main Menu, press . These selections do not affect how the CIM Major and Minor LEDs report alarms. Table 5. Alarm Output Options Alarm When enabled, sends an alarm if. . .
EdgeAccess® Universal Chassis System 4. To enter a new Modem Initialization String, type 5, type the new string, and press ; the default string is "AT". Note: For details on a different initialization string, see the documentation for your modem. 5. To return to the Main Menu, press . Because the DMM defaults to VT100 mode when booting, you cannot see the screens and commands used to switch to SLIP or PPP mode when you exit VT100 mode.
EdgeAccess Universal Chassis System Update Software Each module in the Universal Chassis System has two flash memory banks that store software: • • The Active Flash Memory holds the software currently in use The Inactive Flash Memory holds the new software from a download or the older version of software Software is downloaded to the inactive region to avoid disrupting service. Resetting the module and swapping banks does not affect module operation and is transparent to user traffic.
EdgeAccess® Universal Chassis System 5. When the file transfer is complete: a. At the Software Upgrade menu, type 2, "Swap Bank," and press . b. Type 1, "Software Reset," and press . The 2346 resets and starts using the new firmware. 6. To update a remote partner, type 3, "Copy Software from Source modem to Destination modem," and press . The 2346 writes the software to the remote partner, which then resets and starts using the new firmware.
EdgeAccess Universal Chassis System Change Your Password You can update your password for the 2346 in order to maintain security. You cannot change the password for any other users, especially those who are not logged in. To update your password, follow these steps: 1. From the Utilities menu, type 2, "Change Password," and press . 2. To change your password, follow the prompts on the screen. 3. To return to the Main Menu, press .
EdgeAccess® Universal Chassis System Monitor Modem Performance You can monitor the performance of both the local and remote modems at the Link Errors report. The report includes timers and checks for signal errors. In addition, the 2346 uses the Bit Error Rate Test (BERT), which sends a continuous 127-bit sequence within the optical data stream to check for bit errors while the optical signal remains in sync.
EdgeAccess Universal Chassis System Chapter 4 Maintenance and Troubleshooting Well-maintained modules and cabling can help ensure trouble-free operation. General Maintenance Well-maintained components and clearly identified cables help assure optimum system operation. Damaged fiber cables and dirty connectors are a common source of signal loss or attenuation. Single mode and multimode fiber optics are especially sensitive to contamination.
EdgeAccess® Universal Chassis System Note: For accurate results, warm up each unit for at least 30 minutes before checking power levels. The transmission laser in a 2346 turns on automatically when the chassis receives power. To measure the output power, follow these steps: 1. Clean the connectors on the fiber optic test cable before plugging it in to the Tx connector on the 2346. 2. Warm up each component for at least 30 minutes. 3. Set the optical power meter to the proper wavelength. 4.
EdgeAccess Universal Chassis System The front panel LEDs show both normal and fault conditions. Typically, if a LED is steady red, the fault is in the local 2346; if it blinks red, the fault is in the remote modem. Additional information about fault conditions appears in the System Alarms and System Configuration screens. To aid troubleshooting, Table 1 lists the functions of the front panel LEDs. For details on the LED status during normal start-up and operation, see Chapter 2.
EdgeAccess® Universal Chassis System Problems With Configuration If a configuration error appears and you have difficulty isolating the fault, you can reset all configurable settings to default except for the time and date, password, BOOTP setting, and Telnet timeout. You can then restart your configuration process. To update reset to default, follow these steps: 1. At the Main menu, type 4, "Utilities," and press .` 2.
EdgeAccess Universal Chassis System Loopback Use loopback to diagnose a fault on the optical link, either on a modem or with a cable. The 2346 supports both local and remote loopback in one or both directions. Set loopback either in software for a managed 2346 or at the loopback function switch on a standalone enclosure See Figures 4 through 9. • • • Local loopback returns the received electrical signal to the local site and ignores the received optical signal; turn on Local Loopback at the local modem.
