Mounting the IPS 4345 and IPS 4360 in a Rack with the Slide Rail Mounting System

Rack-Mounting Guidelines


Warning 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

Pay attention to the following guidelines before rack-mounting your appliance:

Allow clearance around the rack for maintenance.

If the rack contains stabilizing devices, install the stabilizers prior to mounting or servicing the appliance in the rack.

When mounting an appliance in an enclosed rack, ensure adequate ventilation. Do not overcrowd an enclosed rack. Make sure that the rack is not congested, because each component generates heat.

When mounting an appliance in an open rack, make sure that the rack frame does not block the intake or exhaust ports.

If the rack contains only one appliance, mount the appliance at the bottom of the rack.

If the rack is partially filled, load the rack from the bottom to the top, with the heaviest component at the bottom of the rack.


Note Use the rack mount brackets to mount the IPS 4345. Use the slide rail mounting system to mount the IPS 4360.


Installing the IPS 4345 in a Rack

The IPS 4345 ships with the rack mount brackets installed on the front of the chassis. Use these brackets to mount the chassis to the front of the rack. If you want to mount the chassis on the back of the rack, you can move the brackets from the front to the back of the chassis.

To rack-mount the chassis, perform the following steps:


Step 1 If you are keeping the front rack mount brackets, go to Step 4. If you want to move the front rack mount brackets to the back of the chassis, go to Step 2.

Step 2 Remove the rack-mount brackets from the chassis as shown in Figure 6-8.

Figure 6-8 Removing the Brackets from the Front of the Chassis

Step 3 Install the brackets on the back of the chassis by attaching the brackets to the holes in the chassis as shown in Figure 6-9. After the brackets are secured to the chassis, you can rack-mount it.

Figure 6-9 Installing the Brackets on the Back of the Chassis

Step 4 Attach the chassis to the rack using the supplied screws (Figure 6-10).

Figure 6-10 Rack-Mounting the Chassis

Step 5 To remove the chassis from the rack, remove the screws that attach the chassis to the rack, and then remove the chassis.


Mounting the IPS 4345 and IPS 4360 in a Rack with the Slide Rail Mounting System

The IPS 4360 ships with the slide rail mounting system, which provides a quick, convenient, and secure method for rack mounting the IPS 4360. You can also use the slide rail mounting system with the IPS 4345. For instructions for using the slide rail mounting system, refer to the Slide Rail Installation Instructions for Cisco IronPort C170, M170, and S170 Appliances and Cisco 5512-X, 5515-X, 5525-X, 5545-X, 5555-X Adaptive Security Appliances and Cisco IPS 4345 and 4360 found at this URL:

http://www.cisco.com/en/US/docs/security/asa/hw/maintenance/5500xspares/slide_rail_installation.html

Although slide rail mounting is preferred for the IPS 4360, in the case of two-rail racks where the slide rails will not fit, you can use the rack mounting brackets. You must order them separately (ASA-BRACKETS=). Note that there will be a slight bend in the brackets when you attach them.

Removing and Installing the Power Supply

This section describes the AC and DC power supplies and how to install and remove them. It contains the following topics:

Understanding the Power Supplies

Removing and Installing the AC Power Supply

Installing DC Input Power

Removing and Installing the DC Power Supply

Understanding the Power Supplies

The IPS 4345 ships with one fixed fan and one fixed power supply (AC or DC) installed. The IPS 4360 ships with one power supply (AC or DC) installed. You can add an additional power supply or you can order the IPS 4360 with two power supplies installed. Having two power supplies installed provides a redundant power option. This configuration ensures that if one power supply fails, the other power supply assumes the full load until the failed power supply is replaced. To maintain airflow, an empty bay must be covered or both bays must be populated with power supplies. If only one power supply is installed, make sure that it is installed in slot 0 (left slot) and that slot 1 (right slot) is covered with a slot cover. If only one power supply is installed, do not remove the power supply unless the appliance has been powered off. Removing the only operational power supply causes an immediate power loss.


Note The IPS 4360 can support two AC or two DC power supplies. Do not mix AC and DC power supply units in the same chassis.


The power supplies each provide 400 W of output power and are used in a 1 + 1 redundant configuration. There is no input switch on the faceplate of the power supplies. The power supply is switched from Standby to ON by way of a system chassis STANDBY/ON switch. The power supply slot numbers are on the back of the chassis to the left side of each power supply. When facing the back of the chassis, power supply slot 0 (PS0) is to the left and power supply slot 1(PS1) is to the right. By default, the factory installs a single power supply in slot 0.

The appliance supports the following power supplies:

AC power supply—Provides 400 watt output power with two DC voltage outputs: +12 V and +5 V. The AC power supply operates between 85 and 264 VAC. The AC power supply current shares on the 12 V output and is used in a dual hot pluggable configuration. The AC power supply consumes a maximum of 471 W of input power.

DC power supply—Provides 400 watt output power with two DC voltage outputs: +12 V and +5.0 V. The power supply operates between -40.5 and -72 VDC. The DC power supply current shares on the 12 V output and is used in a dual hot pluggable configuration. The DC power supply consumes a maximum of 500 W of input power.

Figure 6-11 shows both the removable AC (on the left) and DC (on the right) power supplies for the IPS 4360.

Removing and Installing the AC Power Supply


Caution If you remove a power supply, replace it immediately to prevent disruption of service.


Caution If the appliance is subjected to environmental overheating, it shuts down and you must manually power cycle it to turn it on again.


Warning This unit has more than one power supply connection; all connections must be removed completely to completely remove power from the unit. Statement 102

Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than: 120 VAC, 20A U.S. (240 VAC, 10A international). Statement 1005

Note This procedure applies only to the appliances with a removable AC power supply (IPS 4360).



Note If only one power supply is installed, make sure that it is installed in slot 0 (left slot) and that slot 1 (right slot) is covered with a slot cover.


To remove and install the AC power supply, follow these steps:


Step 1 If you are adding an additional power supply, from the back of the appliance, push the lever on the slot cover to the left to release it, grasp the handle of the slot cover and pull it away from the chassis (Figure 6-12). Save the slot cover for future use. Continue with Step 3.

Installing DC Input Power


Warning The covers are an integral part of the safety design of the product. Do not operate the unit without the covers installed. Statement 1077

Warning When you install the unit, the ground connection must always be made first and disconnected last. Statement 1046

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement 1003

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

Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than: 80 VAC, 20A. Statement 1005

The DC power supply is shipped installed in the chassis, either one or two power supplies depending on which configuration you ordered. You must connect the power supply wires. This section describes how to install the DC power supply ground leads and input power leads to the appliance DC input power supply. Before you begin, read these important notices:

The color coding of the DC input power supply leads depends on the color coding of the DC power source at your site. Typically, green or green/yellow is used for ground (GND), black is used for -48 V on the negative (-) terminal, and red is used for RTN on the positive (+) terminal. Ensure that the lead color coding you choose for the DC input power supply matches the lead color coding used at the DC power source.

Make sure that the chassis ground is connected on the chassis before you begin installing the DC power supply. For more information, see Working in an ESD Environment.

Figure 6-16 shows the back panel of the IPS 4345 with the DC power supply.

Figure 6-17 shows the back panel of the IPS 4360 with two DC power supplies.

Figure 6-17 IPS 4360 Back Panel


Note If only one power supply is installed, make sure that it is installed in slot 0 (left slot) and that slot 1 (right slot) is covered with a slot cover.


To connect the DC power supply on the appliance, follow these steps:


Step 1 Make sure that the chassis ground is connected on the chassis before you begin installing the DC power supply.

Step 2 Turn off the circuit breaker to the power supply.

Step 3 From the front of the appliance, verify that the power switch is in the Standby position.

Step 4 Move the circuit-breaker switch handle to the Off position, and apply tape to hold it in the Off position.

Step 5 Use a 10 gauge wire-stripping tool to strip each of the three wires coming from the DC input power source. Strip the wires to 0.27 inch (7 mm) + 0.02 inch (0.5 mm). Do not strip more than the recommended length of wire because doing so could leave the wire exposed from the DC power supply connection (Figure 6-18).

Figure 6-18 Stripping the DC Input Power Source Wire

1

We recommend that you strip the wire to 0.27 inch (7 mm).



Warning An exposed wire lead from a DC input power source can conduct harmful levels of electricity. Be sure that no exposed portion of the DC input power source wire extends from the terminal block plug. Statement 122

Step 6 Identify the positive, negative, and ground feed positions for the DC power supply connection. The recommended wiring sequence is as follows (Figure 6-19):

Ground lead wire (middle)

Positive (+) lead wire (left)

Negative (-) lead wire (right)

Positive (+) lead wire

   

Figure 6-20 shows the DC power supply with lead wires.

Figure 6-20 DC Power Supply with Lead Wires

Step 7 Insert the exposed end of one of the ground wires into the inlet on the DC power supply. After you push in the wires, they are held in place with a spring, which makes the physical contact. Make sure that you cannot see any wire lead. Only wires with insulation should extend from the DC power supply.

Step 8 Repeat Step 5 through Step 7 for the remaining two DC input power source wires, the positive lead wire and the negative lead wire.

Step 9 Use a tie wrap to secure the wires coming from the power supply to the rack so that the wires cannot be pulled from the power supply by casual contact. Make sure the tie wrap allows for some slack in the ground wire. Figure 6-21 shows the DC power supply with the wires inserted and the tie wrap secured.
