4-Post Installation Instructions
To install a Cisco CDE110 in a 4-post rack using the TMLPMOUNT51 or TMLPMOUNT52 rack mount kit, follow these steps:
Note Although a 2U chassis is shown in the illustrations, these instructions also apply to a 1U (Cisco CDE110) chassis.
Step 1 Attach the two Inner Rails (marked LEFT and RIGHT) to the chassis, each with three 8-32x1/4" SEMS screws.
Step 2 Attach the Universal Front Mounting Bracket to the chassis, each with two 8-32x1/4" SEMS screws.
Note The Universal Front Mounting Bracket can be flipped in order to position the system further forward in the rack (see inset in the next illustration).
Step 3 Using two 8-32 KEPS nuts per L-Bracket, assemble L-Brackets* to the Outer Rail's four outermost threaded studs. (TMLPMOUNT52 contains both EIA and ETSI L-brackets.)
* Note: 23-inch EIA L-brackets are illustrated.
Step 4 Install the Outer Rail subassemblies into the rack using ten or twelve (19" or 23" kits, respectively) 10-32x1/2" SEMS screws. If bar-nuts are used, they should be installed such that all threads are aligned vertically, ensuring the center hole is not skewed with respect to the holes on the rack rail.
Note If mounting a 1U system in a 1U confined space, four 2U bar-nuts are included to replace the 1U bar-nuts. The 2U bar-nuts need to be installed in the 1U space either above or below the 1U space where this kit is being mounted. When installing multiple 1U systems, the 2U bar-nuts should be used in the next to last kit.
Note L-Brackets should be adjusted front-to-back to fit rack depth. The distance between the front equipment mounting rail and rear equipment mounting rail cannot exceed 24 inches.
Step 5 Slide the system into the rack making sure the Inner Rails are captured by the Outer Rails. Support the weight of the system until the lock features on the Inner Rails engage with the slot features on the Outer Rails. An audible `click' will be heard.
Note Once engaged, the lock features must be released to remove the system from the rack. To release the lock features, depress the two latches with the blue arrows (one on either side) downward. While depressing the lock features and supporting the system weight, pull the system out. Pressure can be released once the lock features disengage from the Outer Rail.
Step 6 Install two 10-32X1/2" SEMS screws to hold the Universal Front Mounting Brackets to either the L-Brackets or the rack's equipment mounting rails (23" or 19", respectively).
Note If installing into a 19-inch 4-post rack that has EIA Wide hole spacing, the EIA Wide Adapter bracket must be used. Install this bracket onto the face of the L-Brackets using the same 10-32x1/2" SEMS screws that fasten the L-Brackets to the rack's front equipment mounting rails.
2-Post Installation Instructions
To install a Cisco CDE110 in a 2-post rack using the TMLPMOUNT51 or TMLPMOUNT52 rack mount kit, follow these steps:
Note Although a 2U chassis is shown in the illustrations, these instructions also apply to a 1U (Cisco CDE110) chassis.
Step 1 Attach the two Inner Rails (marked LEFT and RIGHT) to the chassis, each with three 8-32x1/4" SEMS screws.
Step 2 Attach the Universal Front Mounting Bracket to the chassis, each with two 8-32x1/4" SEMS screws.
Note The Universal Front Mounting Bracket can be flipped in order to locate the system further forward in the rack (see inset in the next illustration).
Step 3 Using three 8-32 KEPS nuts per L-bracket, assemble the appropriate L-brackets* and the 2-Post Mounting Bracket to the Outer Rail. (TMLPMOUNT52 contains both EIA and ETSI L-brackets.) The 2-Post Mounting bracket is installed onto the two front-most studs, overlapping the front L-bracket and sharing two threaded studs with it.
* Note: 23-inch EIA L-brackets are illustrated.
Step 4 Install the two Outer Rail subassemblies in the rack using twelve 10-32x1/2" SEMS screws or other appropriate fasteners. If bar-nuts are used, they should be installed such that all threads are aligned vertically, ensuring the center hole is not skewed with respect to the holes on the rack rail.
Note If mounting a 1U system in a 1U confined space, four 2U bar-nuts are included to replace the 1U bar-nuts. The 2U bar-nuts need to be installed in the 1U space either above or below the 1U space where this kit is being mounted. When installing multiple 1U systems, the 2U bar-nuts should be used in the next to last kit.
Note L-Brackets should be adjusted front-to-back to fit rack channel depth.
Step 5 Slide the system into the rack making sure the Inner Rails are captured by the Outer Rails. Support the weight of the system until lock features on the Inner Rails engage with the slot features on the Outer Rails. An audible `click' will be heard.
Note Once engaged, the lock features must be released to remove the system from the rack. To release the lock features, depress the two latches with the blue arrows (one on either side) downward. While depressing the lock features and supporting the system weight, pull the system out. Pressure can be released once the lock features disengage from the Outer Rail.
Step 6 Install two 10-32X1/2" SEMS screws to hold the Universal Front Mounting Bracket to the 2-Post Mounting Bracket.

The ground wire must be #14 to #10 AWG. The ground wire must reach from the Cisco CDE110 to the earth ground to which the ground wire will be attached. |
To ground the Cisco CDE110 to earth ground, follow these steps. Make sure to follow any grounding requirements at your site.
Note The following are generic directions for ground lug installation. Be sure to follow the specific directions provided by the ground lug manufacturer.
Step 1 Locate the ground studs on the Cisco CDE110 back panel. See Figure 1-3 for the location.
Step 2 Use a wrench with a 3/8-inch drive to remove the two nuts that are on the ground studs.
Step 3 If your ground wire is insulated, use a wire stripping tool to strip the ground wire insulation for the correct length. The length of insulation to strip depends on the ground lug you have supplied. See Figure 3-3.
Figure 3-3 Stripping the Ground Wire
Step 4 Slide the open end of the ground lug over the exposed area of the ground wire.
Step 5 Using the correct crimping tool, crimp the ground lug to the ground wire. See Figure 3-4.
Figure 3-4 Crimping the Ground Lug
Step 6 Position the ground lug on the ground studs so that the 90-degree angle is located below the studs. See Figure 3-5.
Figure 3-5 Position of Ground Lug on Studs
Step 7 Use the two nuts that were installed on the ground studs to attach the ground lug and wire assembly to the two ground studs.
Step 8 Use the torque wrench to tighten each nut to 10 in-lb torque.
Step 9 Use an appropriate mechanism to securely attach the other end of the ground wire to a suitable earth ground.
Connecting Cables
The following cable connections are used on the Cisco CDE110:
•For the four Ethernet interfaces on the back of the Cisco CDE110:
–For a Cisco CDE110 that hosts CDS Video Navigator, use Category 5 UTP cables to connect one CDE110 Ethernet interface to the network that includes the set-top boxes that CDS Video Navigator will service, and to connect a second CDE110 Ethernet interface to the network used for management and backoffice communication.
–For a Cisco CDE110 that hosts TV CDSM, use a Category 5 UTP cable to connect one CDE110 Ethernet interface to the network used for management and backoffice communication.
Note For VQE Server and VQE Tools, the Cisco CDE110 models CDE111-2-146TXA-K9 and CDE111-2-146TXD-K9 have six Ethernet interfaces, two of which are on the Intel PRO/1000 PT Dual Port Server Adapter. All other Cisco CDE110 models have four Ethernet interfaces.
–For a Cisco CDE110 that hosts VQE Server (VQE-S), use Category 5 UTP cables to connect up to six CDE110 Ethernet interfaces to Ethernet interfaces on the directly attached edge router. Use Gigabit Ethernet (that is, 1000 Mb Ethernet) interfaces only. For optimal VQE-S performance, the Ethernet interfaces on the Cisco CDE110 should have a direct Layer-3 connection to the edge router.
Note If OSPF routing is used on the Cisco CDE110 hosting VQE-S, the Ethernet interfaces must have a direct Layer-3 connection to the edge router.
–For a Cisco CDE110 that hosts VQE Tools (VQE Channel Provisioning Tool [VCPT] and VQE Client Channel Information Delivery Server [VCDS]), use a Category 5 UTP cable to connect at least one CDE110 Ethernet interface to the same network that the Cisco CDE110s that host VQE-S are on. It is recommended that you use Gigabit Ethernet interfaces.
•If a terminal server is used, the RJ-45 cable from the terminal server is connected to an RJ-45 serial port on the front or back of the Cisco CDE110. Only one serial port can be used because it is one shared serial port.
•If a PC is directly connected to the CDE110 serial port, the cable from the PC is connected to an RJ-45 serial port on the front or back of the Cisco CDE110. Only one serial port (front or back) can be used because it is one shared serial port. The PC end of the cable connected to the CDE110 serial port varies depending on the type of ports supported by the PC.
Note The serial port is used for the system console. A system console is typically used rather than a monitor, keyboard, and mouse directly attached to the Cisco CDE110.
•If a monitor, keyboard, and mouse are used, the cables for the devices are connected to the appropriate connectors on the Cisco CDE110.
See Chapter 1 "Introducing the Cisco CDE110," for the location of connectors on the Cisco CDE110 front and back panels.
To connect network and other cables to the device, follow these steps:
Step 1 For each network connection, insert a Category 5 UTP cable into a NIC connector on the Cisco CDE110 back panel. (See Figure 1-3.)
Step 2 Connect the other end of the network cable to the appropriate device (router, hub, or switch) in your network.
Step 3 For the system console, connect an RJ-45 cable from the terminal server to an RJ-45 serial port on the front or back of the Cisco CDE110.
Step 4 If required in your installation, connect cables for other devices, such as keyboard, monitor, and mouse, into the appropriate connectors.
See Chapter 1 "Introducing the Cisco CDE110," for the location of connectors on the Cisco CDE110 front and back panels.

Step 4 Slide the green safety lock (D in Figure 3-13) to the left to disengage the power supply module.
Step 5 Grasp the handle (B in Figure 3-13) and pull the power supply from the chassis.
Installing a DC Power Supply
To install a DC power supply, read these sections in the order listed:
1. Recommended Tools and Supplies
2. Installing a DC Power Supply and Connecting to a DC Power Source
If redundant DC power supplies are used, separate DC power sources are needed for each power supply. This allows you to turn off power for one power supply without affecting the power source for the other power supply.
If only one power supply module is installed, it must be in the right slot and a power supply filler panel must be installed in the left slot to ensure proper system cooling. See
Figure 1-10.

Installing a DC Power Supply and Connecting to a DC Power Source
To connect a DC power supply to a DC power source, follow these steps:
Step 1 Review and follow all safety information in Chapter 2 "Preparing to Install the Cisco CDE110," including the section "If DC Power Supplies Are Installed" section.
Step 2 Before proceeding, ensure that the system (earth) ground connection has been made, following the instructions in the "Grounding the Cisco CDE110" section.
|
Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024

Step 4 Verify that the power is off to the DC circuit for the power supply you are installing.
|
Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement 1003
|
Note When you removed the failed power supply from the Cisco CDE110, you set aside the Molex connector with the DC input wires in place. That Molex connector is used in the next step.
Step 5 Insert the Molex connector (with the DC input wires installed) into its mating connector on the power supply unit (see Figure 3-16). The Molex connector snaps into place when it is fully inserted.
Figure 3-16 Inserting the Molex Connector
Step 6 After confirming that all installation steps are correctly completed, restore power to the DC circuit for the power supply you are installing.
Booting the Cisco CDE110
If the Cisco CDE110 has been powered down for the power-supply installation, follow these steps to boot the CDE110:
Step 1 Power up any externally connected devices.
Step 2 Press the power switch on the front panel.
The system should begin booting.
Step 3 Once the operating system boots, observe the front panel LEDs to verify that your system is operating properly. For information on these LEDs, see the "Front Panel" section.
Removing and Replacing a Hard Disk Drive
This section explains how to remove and replace a hard disk drive (HDD).
Note The hard disk drives are customer-replaceable on all CDE110 models except CDE110-1-036TXA-K9 and CDE110-1-036TXD-K9.
The CDS Video Navigator models of the CDE110 use RAID 1 disk duplexing. RAID 1 requires two drives because all data is stored twice, once each on two identical disks, making one drive a mirror image of the other. If one hard disk fails, all data is immediately available on the other without an impact on performance.
By default on the Cisco CDS Video Navigator models of the CDE110, two drives are configured as a RAID 1 disk-duplexed pair, and the third drive is configured as a hot spare. In the RAID 1 disk-duplexed pair, a hard disk drive is hot-swappable without loss of data only if the other disk in the pair holds the complete set of stored data and is functioning correctly.
The CDS Video Navigator and TV CDSM models of the CDE110 require three hard disk drives. Do not leave a drive bay empty. Before replacing a failed hard disk drive, have the replacement drive on site ready to be installed.
Hard Disk Drive Cautions
Hard disk drives are complex electromechanical systems that are quite delicate. They are subject to permanent damage from relatively low levels of both mechanical and electrical shock. Review the following cautions to prevent damage while handling and installing an HDD.
Electrostatic discharge (ESD) can damage disk drives, boards, and other parts. To provide some ESD damage protection when removing and installing a disk drive, wear an antistatic wrist strap attached to a bare metal, unpainted surface on the rackmount.
Dropping an HDD from as little s 10mm (less than half an inch) onto a hard surface can create up to 900g of force, exceeding the shock specifications of most hard disk drives.
Do not strike the HDD unit with another object or HDD unit.
Do not stack HDD units on top of each other unless they are properly secured in a rack or chassis intended for stacking.
Do not stand HDD units on their edge. They may fall over.
If the HDD PC card is exposed in the HDD unit, avoid touching the PC card. If you must touch the PC card, take ESD precautions (such as using an ESD mat and wrist strap).
If the SATA or SAS connector pins are exposed, avoid touching them. If you must touch them, take ESD precautions (such as using an ESD mat and wrist strap).
HDD units should not be moved or transported while the power is on and the disk drive is spinning.
HDD units should normally only be installed or removed from a system with the system power off (preferably the system should be unplugged).
