Product Description

The XPS is an expandable power system that can support nine network switches.

Figure 1-1 Cisco XPS 2200

The XPS has two field-replacable-unit (FRU) power supply modules that are inserted into the slots on the XPS rear panel. You can use any combination of C3KX-PWR AC or DC power supply modules. See the "Power Supply Modules" section for more information.

The nine XPS power ports provide the power and management signals to the Catalyst 3750-X and 3560-X switches. The XPS communicates with each switch through the XPS cable.

When you connect Catalyst 3750-X or 3560-X switches to the XPS, you create a power stack.

You can configure the XPS for redundancy, power sharing, or both.

In redundant mode, the XPS provides power backup for up to two failed power supplies. When in redundant mode, each power supply can provide redundancy for a single power supply of equal value or less. The failed power supplies can be in different switches or in the same switch.

In power-sharing mode, the XPS supplies power to the switches in the power stack (only Catalyst 3750-X switches running the IP base image). The power of all the power supplies in the stack (including the XPS) is aggregated and distributed among the stack members.

In mixed-mode, where one power supply is in redundant mode and one power supply is in power-sharing mode, the XPS provides power backup for only one failed power supply.

Front Panel Description

The XPS front panel has system LEDs, a Select button, an Online/Offline button, fan modules, and a service port (Figure 1-2).

The S-PWR and XPS LEDs show the mode and status of the XPS power ports that you use to connect the XPS to the switch. The LEDs are numbered 1 to 9, which corresponds to the numbers on the power ports. For each numbered LED, only one LED is illuminated, depending on the mode for that port.

Table 1-3 lists the LED colors and their meanings.

Select and Online/Offline Buttons

The XPS has a Select button and an Online/Offline button. You can use these buttons to select a port and change its operation mode (enabled or disabled). Figure 1-4 shows the Select and Online/Offline buttons.

Online/Offline button


Use the Select button to select an XPS power port. Use the Online/Offline button to change the operation mode of the selected port.


Note The XPS and all ports are in enabled mode when it powers up.


To change the operation mode of a port, follow these steps:


Step 1 Press the Select buttonrepeatedly until the desired port blinks amber and green.

Step 2 Press the Online/Offline button to place the port in either enabled or disabled mode.


Note If you press the Online/Offline button on the XPS before pressing the Select button, the XPS toggles all nine ports between enable mode and disable mode. If this occurs, press the Select button again to select the desired port.


Step 3 Repeat this procedure as necessary to change the operation mode of any of the other ports.


Fan Modules

The XPS supports hot swapping of the three fan modules. You can remove and replace them without disconnecting the system power and without interrupting normal system operation. For information about installing and removing the fan modules, see the "Installing a Fan Module" section.

Service Port

Use the Service port to upgrade the image on the XPS. Refer to the Configuration Notes for the Cisco eXpandable Power System 2200 for software upgrade information.

Rear Panel Description

The XPS rear panel has a reset button, nine power ports, and two power supply module slots (Figure 1-5).

Reset Button

Press the reset button to perform a soft reset. Press and hold the reset button (more than 5 seconds) to power cycle the XPS.

Power Ports

The power ports provide the power and communication signals to the Catalyst 3750-X and the 3560-X switches. Two types of XPS cables connect the XPS to the switch. See the "Cabling Options" section.

Power Supply Modules

The XPS power supply modules slide into the power supply slots in the rear of the XPS.

The 350-W and 715-W AC power supply modules are autoranging units that support input voltages between 100 and 240 VAC.

The 1100-W power supply module is an autoranging unit that supports input voltages between 115 and 240 VAC.

The 440-W DC power supply module has dual input feeds (A and B) and supports input voltages between 36 and 72 VDC. The output voltage range is 51 to 57 V.

Each AC power supply module has a power cord for connection to an AC power outlet. The DC power supply module must be wired to a DC power source.

1 Not NEBS compliant.



Note For systems configured for redundant mode, the lowest-rated power supply module in the XPS must be equal to or greater than the highest-rated power supply module in the switch.



Note If you ordered one power supply module, a spare power supply insert ships with the XPS. If you ordered two power supply modules, you can order the power supply insert (C3KX-PS-BLANK=) as a spare part.


If only one power supply module is installed in the XPS, the empty power supply slot in the XPS rear panel must have the spare power supply insert installed. The insert maintains proper airflow and cooling.


Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029

Caution Operating the XPS without the insert installed in the power supply slot can cause the XPS to overheat, and serious XPS faults might occur.

For information about installing and removing the power-supply modules and for power supply specifications, see Chapter 3 "Power Supply and Fan Module Installation" and "Technical Specifications."

Management Options

When the Catalyst 3750-X or 3560-X switch is atached to the XPS, you can configure and manage the XPS through the switch software:

Cisco Network Assistant

Cisco Network Assistant is a PC-based network management GUI application optimized for LANs of small and medium-sized businesses. Cisco Network Assistant offers centralized management of Cisco switches ranging from the Catalyst Express 500 through the Cisco Catalyst 4506. Through a GUI, users can configure and manage switch clusters or standalone switches. Cisco Network Assistant is available at no cost and can be downloaded from this URL:

http://www.cisco.com/pcgi-bin/tablebuild.pl/NetworkAssistant

For information on starting the Network Assistant application, see the Getting Started with Cisco Network Assistant guide on Cisco.com.

Cisco IOS CLI

The switch CLI is based on Cisco IOS software and is enhanced to support desktop-switching features. You can fully configure and monitor the switch and switch cluster members from the CLI. You can access the CLI either by connecting your management station directly to the switch management port or a console port or by using Telnet from a remote management station. See the switch command reference on Cisco.com for more information.

CiscoWorks application

The CiscoWorks LAN Management Solution (LMS) is a suite of management tools that simplify the configuration, administration, monitoring, and troubleshooting of Cisco networks. See the LMS documentation for more information.

SNMP network management

You can manage switches from a Simple Network Management Protocol (SNMP)-compatible management station that is running platforms such as HP OpenView or SunNet Manager. The switch supports a comprehensive set of Management Information Base (MIB) extensions and four Remote Monitoring (RMON) groups. See the switch software configuration guide on Cisco.com and the documentation that came with your SNMP application for more information.
