In a redundant setup with a V.35 link to two Comtech modems, a special Y cable is needed. This cable links both units serial interface ports into a 1+1 (hot standby) setup. With this cable, both units actively listen to the incoming traffic. Internal management assures only one unit sends traffic onto the interface (the active unit). The redundant EIA-530/V.35 Y cable adaptor is available for all CX-U units. Serial Interface Speeds EIA-530 Signal Handling TX and RX LEDs The EIA-530 serial interface supports asynchronous or synchronous transmission at speeds up to 8,192 Mbps. The EIA-530 port can operate at 375 bps - 8,192 Mbps for external or internal clocking. Signaling through the EIA-530 port complies fully with the ITU-T s (CCITT) V.35 standard. Signaling, however, occurs through a generic DB-25 (RS-530) connector. These LEDs operate the same way as the V.35 LEDs in the front of the unit. As extracted from Table 2-2: 2-16 Memotec Inc.

34 CX-U Series Hardware Reference Manual 2.4 About the DLP and DDLP cards In addition to the hardware pre-installed on the motherboard of your unit, you can also add extra daugthercards which add processing power to your unit. Each DSP on these daughtercards can handle one or more T1/E1 ports, depending on which DSP application is active. For example, the EdgePlus DSP application can only handle one T1/E1 port, while the AbisXpress DSP application can handle two T1/E1 ports. NOTE: Other factors can influence the number of ports a DSP resource can support. To determine the number of DLP/DDLP cards you need for your network, please contact your Memotec representative. There are two types of daughtercards you can add to your CX-U unit: A DLP (Digital line processor) card has a single DSP resource that is used to compress traffic. The DDLP (Dual Digital line processor) has a dual DSP resources which doubles the processing power. Only the CX-U1000 series of units (revision 6 or later) supports the DDLP cards.

52 CX-U Series Hardware Reference Manual Adding a Redundant Backplane to Two Units Adding a Redundant Backplane requires that you have two CX-U units, stacked one atop the other. 1. Remove the Redundant Backplane from its packaging (if you have not already done so). 2. Carefully line up all connectors located at the rear of the units, and push the backplane into place. 3. Fasten the ten retaining screws, to ensure all interface connectors have solid contact with the backplane. Figure 5-2: Attaching the Redundant Backplane NOTE: If you also have the protective plates, you need to add them after the backplanes. For more information, see Protective Plates on page A Memotec Inc.

53 Installation and Configuration Removing a Faulty Unit This procedure assumes you have followed the instructions in Adding a Redundant Backplane to Two Units on page 5-4 and one of the two units has failed. In a typical setup, the top unit handles the traffic (master or main CX-U), except when a failure is detected on it. The bottom unit is the backup or slave CX-U. For this procedure, call Unit A the failed unit, and Unit B the redundant backup that takes over. 1. It is mandatory that Unit A has been powered off when connecting and disconnecting from the backplane. This ensures that any traffic being carried in Unit A will automatically shift to Unit B. 2. Remove the five retaining screws from the Unit A, and put them aside for later use. 3. Remove the front rackmount screws, then carefully separate the backplane from Unit A. Removing and installing the top unit can be performed by one person. However, removing and installing the bottom unit requires two people. When the front rackmount screws have been removed from the bottom unit, it is no longer supported, a second person is needed to hold the bottom unit during the procedure. 4. Replace Unit A with another unit. 5. Replace the five retaining screws. You may consult the Status Active LEDs (shown in Figure 2-2 in Chapter 2) to help determine which unit is carrying traffic.

62 CX-U Series Hardware Reference Manual 5.4 Vertically Mounting CX-U Units In certain cases, it is recommended that you mount the CX-U units vertically. For more details, please consult the Product Information Note entitled Thermal Management When Installing the CX-U1240 In The Hub which is available on the Memotec product CD, or directly from Memotec Vertically Mounting CX-U Units Please follow these instructions for vertically mounting CX-U units. This procedure assumes that you have followed all necessary procedures outlined above for your application, such as in Adding DLPs or DDLPs to a Motherboard on page 5-6 (for adding DLPs) or Adding a Redundant Backplane to Two Units on page 5-4 (for adding redundant backplanes), as they apply to you, and are ready to mount the units onto a rack. This procedure also assumes that you have ordered and received a fuse panel (CB- PWXHD-3), and the CX-U vertical mounting hardware (CB-UVMH-10, consisting of a pair of rails to hold up to ten CX-U units vertically). You will also need a heat deflector. NOTE: Vertical mounting of CX-U units are recommended when operating above an ambient temperature of 25 C. The harsh conditions or the cabling on each side of the units can limit the air flow within the units. The NEBS recommended operation temperature is 5 C to 40 C. To vertically mount a CX-U unit, follow these steps: 1. Install the fuse panel by fastening the four Phillips screws into place. 2. Below the fuse panel, install the CX-U vertical mounting rails onto your standard 40/ 44 U rack by fastening the four Phillips screws into place. 3. Place the CX-U units, one at a time (or, in a redundant setup, two at a time) by carefully turning them vertically, making sure the Memotec logo is on the bottom. 4. Fasten the four retaining screws to the vertical mounting rails. 5. Repeat until all units are installed (10 units maximum per row). 6. If you are installing more than ten units, add the heat deflector below the first row of ten CX-U units. Tighten all retaining screws to the rack. 7. Repeat steps 1-6 for the next ten units (if necessary). 8. Repeat, if necessary, for the last ten units. Up to three rows of ten CX-U units can be mounted onto a standard 40/44 U rack. Each row should be separated by a heat deflector, ensuring all units receive fresh air from the bottom. See Figure 5-12 to see an actual setup Memotec Inc.
