Installing the AC Power Shelf

This section describes how to install the AC power shelf (see Figure 1) in a rack and connect it to your power supplies. You can install one or two 2500 W power supplies (see Figure 2) in the AC power shelf, depending on how much power is required.


Warning Read the installation instructions before connecting the system to the power source. Statement 1004

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030

Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. Statement 1017

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

Warning The plug-socket combination must be accessible at all times, because it serves as the main disconnecting device. Statement 1019

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. Statement 43

Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040

Figure 1 AC Power Shelf

Figure 2 2500 W AC Power Supply

Required Tools

You will need the following tools to perform the procedures in this section:

Number 1 and number 2 Phillips screwdrivers to tighten the captive installation screws on most systems

3/16-inch flat-blade screwdriver to open the power supply release mechanism and for the captive installation screws on the supervisor engine and switching modules on some systems

Antistatic mat or antistatic foam in case you need to remove switching modules to troubleshoot the installation

Rack-mount kit

Tape measure

Level

Your own electrostatic discharge (ESD) grounding strap or the disposable ESD strap included with the system

11 mm or 7/16 inch wrench or socket for the output terminal nuts

Torque wrench and 11 mm or 7/16 inch socket (if you will be installing a strapping kit)

Rack-Mounting and Connecting the AC Power Shelf


Warning

To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. Statement 1006



Note Install your AC power shelf close enough to your Catalyst 4500 series switch so that you can connect the power cable to the switch. It is recommended that you install the AC power shelf directly above your Catalyst 4500 series switch or in a directly adjacent rack.


To mount the AC power shelf on an equipment rack and connect it to your switch, follow these steps:


Step 1 Align the mounting holes of the L brackets with the mounting holes of the equipment rack.

Step 2 Secure the AC power shelf using four (two per side) 12-24 x 3/4-inch screws through the elongated holes in the L bracket and into the threaded holes in the mounting post. (See Figure 3.)

Figure 3 Mounting the AC Power Shelf on the Rack

Step 3 Using a tape measure and a level, ensure that the AC power shelf is mounted straight and level.

Step 4 Remove the spacer bar.

Step 5 If installing a second shelf in parallel, refer to the "Installing a Second Shelf" section.

Step 6 Make sure that the power switch on the output panel is off.

Step 7 Using the CAB-4502-DC-2M or CAB-4502-DC-60CM cable set, connect the ground and power terminals on the shelf to the DC input terminals on the switch.

Step 8 Install the service access cover (WS-X4500-PS01) over the DC terminals on the power shelf as described in the following sub steps:

a. Insert the tabs on the service access cover into the slots to the left of the terminals.

b. Bend the service access cover around the terminal block, allowing the corners to poke through the slots on the cover.

Figure 4 Installing the Service Access Cover

c. Insert the tabs on the front of the service access cover into the slots to the right of the terminals.


Caution Turn off the Catalyst 4500 series switch and unplug the power cord or cords providing AC input power before removing or replacing the service access cover.


Warning This product must be connected to a power-over-ethernet (PoE) IEEE 802.3af compliant power source or an IEC60950 compliant limited power source. Statement 353

Step 9 Connect the RS-485 cable (straight-through CAT5 cable commonly used in Ethernet connections) from an RJ-45 connector on the AC power shelf output panel to the RJ-45 connector on the DC-input power supply in your Catalyst 4500 series switch. (See Figure 5.)

Figure 5 Connecting the RJ-485 Cable

Step 10 Install the power supplies. Refer to the "Installing a Power Supply" section.

Step 11 Power on the power switch on the AC power shelf output panel.


Installing a Power Supply

You can install one or two power supplies into the AC power shelf. There are two slots to the right of the output panel as shown in Figure 1.


Note Do not install the power supplies until the shelf is mounted in the rack.


To install a power supply in an AC power shelf, follow these steps:


Step 1 Use a flat-blade screwdriver to unlatch the power supply frame as shown in Figure 6.

Figure 6 Using a Screwdriver to Unlatch the Front Panel of the Power Supply

Step 2 Pull the power supply frame downward as shown in Figure 7.

Figure 7 Pulling the Power Supply Frame Downward

Step 3 Align the power supply in a AC power shelf slot and gently slide it into the slot as described in the following substeps:

a. Make sure the hinges on the bottom of the power supply frame connect with the arc-shaped slots on the frame of the voice power module.

b. Slide the power supply into the slot, making sure that the frame closes completely and the latch clicks into the closed position as shown in Figure 8.

Figure 8 Sliding the Power Supply into the AC Power Shelf Slot

Step 4 Plug one power cord (250 V, 20 A [U.S.A.]) into each installed power supply as shown in Figure 9. The power connector is on the back of the power supply.

Figure 9 Plugging in the Power Cords


Installing a Second Shelf

Two voice power shelves can be connected in parallel to provide power to a Catalyst 4500 series switch. This will require a strapping kit, which can be ordered separately. To connect the shelves, follow these steps:


Step 1 Install the first shelf as described in Steps 1-4 of the "Rack-Mounting and Connecting the AC Power Shelf" section.

Step 2 If the power supplies are already installed in the first shelf, disconnect the AC power cord from each power supply or remove the power supplies from the shelf. Turning the power supply off does not disable power from the power terminals.


Warning This unit might have more than one power supply connection. All connections must be removed to de-energize the unit. Statement 1028

Step 3 Using a pair of pliers, remove the breakaway tab on the top of the output panel of the AC power shelf you just installed, and remove the breakaway tab on the bottom of the output panel of the secondary AC power shelf.

Figure 10 Locating the Breakaway Tabs

Step 4 Install the second shelf in the rack. Do not leave a gap between the shelves, install the second shelf directly on top of the first.

Step 5 Remove the shelf paralleling cover from both shelves using a Phillips screwdriver.

Step 6 Remove the nuts on the power terminals using an 11-millimeter or 7/16-inch wrench.

Step 7 Attach the strapping kit tabs to the power terminals.

Figure 11 Attaching the Strapping Kit

Step 8 Replace and tighten down the nuts removed in Step 5. Do not tighten more than 65 inch pounds
(7 Newton meters).

Step 9 Connect the wires attached to the strapping assembly to the signalling ports on both shelves.


Warning This product must be connected to a power-over-ethernet (PoE) IEEE 802.3af compliant power source or an IEC60950 compliant limited power source. Statement 353

Step 10 Replace the shelf paralleling covers on both shelves.

Step 11 Attach the current and ground connectors as described in Step 6 to Step 8 of the "Installing the AC Power Shelf" section
