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.

4.1 GPS Clock Solution
The CX-U GPS clock solution (GPS-CLK-2) provides remote locations with an accurate
timing source when the clock reference cannot be economically carried. The GPS solution
is composed of three main components: the GPS clock module, the GPS antenna, and the
surge (lightning) protection device, which are described in the following sections. Figure4-1 shows these main components, as well as cables, adaptors and connectors required to
setup the entire GPS solution.
4.1.1 GPS Clock Module
This small module, shown in Figure 4-2, mounts directly onto the CX-U motherboard. It is
specifically designed for use in remote synchronization and timing applications. The
reference synchronization is highly accurate and can achieve full PRC MTIE
performance. It has a self-survey mode of operation that allows the module to provide
accurate timing even with only one satellite being tracked. It provides reference timing to
all T1/E1, serial links (V.35/EIA-530) and external equipment using the SYNC Output.
Table 4-1 summarizes its specifications. For instructions on installing the module, please
see Adding a GPS Module on page 5-11.

5.1.4 Removing a Faulty Uni t
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.

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 entitledThermal Management When
Installing the CX-U1240 In The Hub which is available on the Memotec product CD, or
directly from Memotec.
5.4.1 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) orAdding 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 of25C. 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 5C to 40C.
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.

A.5 Protective Plates
You must attach protective metal plates to the back of the unit, directly behind the
backplanes. These metal plates help to protect the backplanes from any physical damage,
as well as prevent you from inadvertently shorting them out (for example, with a
screwdiver), which could cause link interruptions.
To attach these protective plates, you can re-use the screws that hold the backplanes in
place. Included in each protective plate kit are metal separators that you must placebetween the backplane and the protective plate.
