Air filter and chassis blower replacement (21 pages)
Summary of Contents for Cisco 7010
Customer Order Number: DOC-781233= This document contains instructions for replacing the 600W, AC-input power supply and the fan tray, both of which are available as spare parts for the Cisco 7010 and Cisco 7505 chassis. Note When referring to both the Cisco 7010 and Cisco 7505 chassis, chassis will be used.
Route Switch Processor (RSP1) is a required system component and occupies the top slot. In both chassis, the remaining interface slots (three in the Cisco 7010 and four in the Cisco 7505) support any combination of available interface types: Ethernet, Token Ring, FDDI, serial, HSSI, and so forth.
Fan tray Power Supply The Cisco 7010 and Cisco 7505 come equipped with one 600W, AC-input power supply. Table 1 lists the power speciﬁcations for the Cisco 7010 and Cisco 7505. The following sections describe the 600W, AC-input power supply and the fan tray. For descriptions of other system components, refer to the Cisco 7010 Hardware Installation and Maintenance or Cisco 7505 Hardware Installation and Maintenance publications.
Product Overview Frequency 50 to 60 Hz Power distribution 70A maximum @ +5 VDC, 15A maximum @ +12 VDC, 3A maximum @ –12 VDC, and 5A maximum @ +24 VDC On the noninterface processor end of the power supply, two handles provide grip points for pulling the power supply out of the chassis.
Product Overview Fan Tray The fan tray comprises six individual axial fans and a printed circuit board (with the control circuits) mounted on a metal plate. (See Figure 2.) The fans draw cooling air through the chassis interior to maintain an acceptable operating temperature for the internal components. The fan tray slides into the right side of the chassis from the noninterface processor end of the router.
Prerequisites Prerequisites Before you begin this installation, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment. This section also provides a list of the tools that you need to perform this replacement. Safety Guidelines When working with any electrical equipment, the following guidelines will help to ensure your safety and protect the equipment.
If a power strip or other equipment obstructs access, you will have to remove the chassis from the rack before replacing the component. Refer to the Cisco 7010 Hardware Installation and Maintenance or Cisco 7505 Hardware Installation and Maintenance publications for the tools you will need and descriptions of the rack mounting hardware.
Replacing Components Preventing Electrostatic Discharge (ESD) Damage Electrostatic discharge (ESD) damage, which can occur when electronic boards or components are handled improperly, can result in complete or intermittent failures. The RP, SP, and interface processors each comprise a printed circuit board that is ﬁxed in a metal carrier. EMI shielding, connectors, and a handle are integral components of the carrier.
Replacing Components Removing and Replacing the Chassis Cover Panel The two captive slotted screws are the only fasteners on the cover panel. (See Figure 5.) Five shallow tabs at the bottom edge of the panel ﬁt into slots at the base of the chassis opening. The tabs act as a pivot point for pulling the top of the panel away from the chassis opening, and as guides to align the panel when replacing it.
Replacing Components Removing and Replacing the Fan Tray When viewing the chassis from the noninterface processor end, the fan tray is on the far right. (See Figure 2.) A cutout in the front of the tray provides a handle for pulling the tray out of the chassis. An M4 Phillips screw anchors a tab on the lower left side of the tray to the interior chassis frame, just below the right power supply ear.
Replacing Components Figure 6 Replacing the Fan Tray Removing/replacing fan tray Step 6 Insert the top runner of the fan tray through the notch in the top of the chassis. Continue pushing the tray into the chassis, and ensure that the bottom runner slides into the track on the ﬂoor of the chassis.
