Safety Information
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 Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. Statement 12
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
An ESD wrist strap is included with the system to protect sensitive electronics and should be connected to a bare metal surface to act as a ground. This ensures that all components have the same charge. An ESD wrist strap should be used when working with internal components that are installed in the shelf. If rear access is available, the wrist strap can connect at the rear of the system shelf as shown in Figure 1.
Figure 1 ESD Wrist Strap Connection Point
Keep the system area clear and dust-free during and after the installation.
Always check for possible hazards before beginning work.
Remove the Controller Tray
Step 1 Locate the controller faceplate on the system shelf.
Step 2 To access the sliding controller tray, remove the controller faceplate by loosening the two front thumbscrews ( Figure 2).
Figure 2 Removing the Controller Faceplate
Step 3 Slide the controller tray out and away from the system shelf to access the connections on the Alarm Interface Board ( Figure 2 #2).
Step 4 Remove the terminal block on the Alarm Interface Board ( Figure 3).
Figure 3 Inserting or Removing the Terminal Block
Step 5 Remove the following alarm cable connections in ( Figure 4 or Figure 5 #2, depending on your controller hardware).
•J16 terminal block
•J15 terminal block
•J14/J13 terminal blocks
Note If alarm cables are not labeled with the jumper number, label the cables with the appropriate jumper number: J16, J15, J14 (1,2,3), and J14 (4,5,6)/J13 for the system without an LCD display..

Step 6 Remove the intra-shelf communications cabling:
•J9 terminal block ( Figure 5 or Figure 4 #3)
•J8 terminal block ( Figure 5 or Figure 4 #4)
•J1 Ethernet cable ( Figure 5 or Figure 4 #5)
•J1 terminal block ( Figure 5 or Figure 4 #6)
Note When the controller is disconnected from the system, the rectifiers return to their default voltage (53.5 VDC). The change in voltage will not have an effect on the load. The output will remain at 53.5 VDC until the new controller tray is installed and activated.
Step 7 Remove the controller tray ground connection by removing the Phillips head screw ( Figure 5 or Figure 4 #7).
Step 8 Remove the wire tie holding the controller tray in the system shelf ( Figure 5 or Figure 4 #8).
Step 9 Pull the controller tray out of the system shelf.
Install the Replacement Controller Tray
Step 1 Place the controller tray in the system shelf.
Step 2 Reinstall the controller tray ground connection by connecting the Phillips head screw ( Figure 5 or Figure 4 #7).
Step 3 Use a new wire tie to replace the one that was removed in the previous procedure.
Step 4 Reconnect intra-shelf communications cabling ( Figure 3); cables are labeled with the appropriate jumper number:
•J9 terminal block ( Figure 5 or Figure 4 #3)
•J8 terminal block ( Figure 5 or Figure 4 #4)
•J1 Ethernet cable ( Figure 5 or Figure 4 #5)
•J1 terminal block ( Figure 5 or Figure 4 #6)
Step 5 Reconnect the following alarm cable connections ( Figure 5 or Figure 4 #2).
•J16 terminal block
•J15 terminal block
•J14/J13 terminal blocks
Step 6 Slide the controller tray back into the system shelf.
Step 7 Replace the controller faceplate by attaching it to the system shelf and tightening the two front thumbscrews.
Step 8 After installing the controller, the controller and rectifier LEDs will start to blink. It may take a few minutes for the controller to communicate with all rectifiers. At this point, all rectifier output voltages will return to the programmed level. Load output is not affected while the LEDs are blinking.

Obtaining Technical Assistance
For all customers, partners, resellers, and distributors who hold valid Cisco service contracts, Cisco Technical Support provides 24-hour-a-day, award-winning technical assistance. The Cisco Technical Support Website on Cisco.com features extensive online support resources. In addition, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not hold a valid Cisco service contract, contact your reseller.
Cisco Technical Support Website
The Cisco Technical Support Website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, 365 days a year, at this URL:
http://www.cisco.com/techsupport
Access to all tools on the Cisco Technical Support Website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:
http://tools.cisco.com/RPF/register/register.do
Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support Website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
