Removing and Installing the Supervisor Engine

All Catalyst 4500 E-series switches support hot swapping, which lets you install, remove, replace, and rearrange supervisor engines and switching modules without powering the system off. When the system detects that a switching module has been installed or removed, it runs diagnostic and discovery routines automatically, acknowledges the presence or absence of the module, and resumes system operation with no operator intervention.

This section contains the following subsections:

Required Tools


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



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


Required Tools

You will need the following tools to install a supervisor engine in a Catalyst 4500 series switch:

  • Number 2 Phillips-head screwdrivers for the captive installation screws
  • 3/16-in. flat-blade screwdriver for the captive installation screws on other modules
  • Antistatic mat or antistatic bag
  • ESD wrist strap or other grounding device

Note Whenever you handle supervisor engines, use a wrist strap or other grounding device to prevent electrostatic discharge (ESD) damage.


Preventing Electrostatic Discharge Damage

ESD damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Printed circuit boards that are installed in metal carriers that are Electromagnetic interference (EMI) shielded. Although the metal carrier helps to protect the circuit board from ESD, use a preventive antistatic strap when you handle the supervisor engine.

Follow the listed guidelines to prevent ESD damage:

  • Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
  • Connect the equipment end of the strap to an unfinished chassis surface.
  • When installing a component, use any available ejector levers or captive installation screws to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.
  • When removing a component, use any available ejector levers or captive installation screws to release the bus connectors from the backplane or midplane.
  • Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.
  • Place a removed component board-side-up on an antistatic surface or in a static shielding container. If you plan to return the component to the factory, immediately place it in a static shielding container.
  • Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages on the body; ESD voltages on clothing can still cause damage.
  • Never attempt to remove the printed circuit board from the metal carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm (Mohm).

Installing the Supervisor Engine

Catalyst 4500 E-series switches have horizontal chassis slots that are numbered sequentially from top to bottom. The Supervisor Engine 8-E is supported in the following chassis slots:

  • Catalyst 4503-E: Slot 1 only
  • Catalyst 4506-E: Slot 1 only
  • Catalyst 4507R+E: Slot 3 and slot 4 (redundant supervisor engines supported)
  • Catalyst 4510R+E: Slot 5 and slot 6 (redundant supervisor engines supported)

Note Both supervisor engines in a redundant configuration must be of the same type.



Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034



Caution To prevent ESD damage, handle supervisor engines by the carrier edges only.

To install a supervisor engine in the chassis, follow these steps:


Step 1 Take the necessary precautions to prevent ESD damage as described in the installation guide for your switch.

Step 2 Ensure that you have enough clearance to accommodate any interface equipment that you will connect directly to the supervisor engine ports.

Step 3 Loosen the two captive installation screws that secure the switching-module filler plate or the existing supervisor engine (whichever is present) and remove it.

Step 4 Remove the supervisor engine filler plate or the existing supervisor engine from the slot. If a switching module filler plate is being removed, set it aside and save it for future use. If you are removing an existing supervisor engine, see the “Removing the Supervisor Engine” section.

Step 5 Remove the new supervisor engine from the shipping packaging.

Step 6 Grasp the switching module front panel with one hand and place your other hand under the carrier to support the supervisor engine, as shown in Figure 2. Do not touch the printed circuit boards or connector pins.

Step 7 Align the edges of the supervisor engine carrier with the guides on the sides of the switch chassis slot, as shown in Figure 2.

Figure 2 Installing the Supervisor Engine in the Chassis (Catalyst 4507R+E Shown)

 

Step 8 Pivot the two module ejector levers out and away from the faceplate.

Step 9 Carefully slide the supervisor engine into the slot until the notches on both ejector levers engage the chassis sides.

Step 10 Simultaneously pivot in both ejector levers so that they are parallel with the supervisor engine faceplate to fully seat the supervisor engine in the backplane connector.


Caution Always use the ejector levers when installing or removing a supervisor engine. A supervisor engine that is partially seated in the backplane will not function correctly.

Step 11 Use a screwdriver to tighten the two captive installation screws on the supervisor engine. Do not over tighten the captive installation screws.


 

To check the status of the module, follow these steps:


Step 1 Verify that the supervisor engine STATUS LED is lit.

Step 2 Periodically check the STATUS LED

  • If the STATUS LED changes from orange to green, the supervisor engine has successfully completed the boot process and is now online.
  • If the STATUS LED remains orange or turns red, the supervisor engine has not successfully completed the boot process and may have encountered an error.

Step 3 When the switch is online, enter the show module command. Verify that the system acknowledges the new supervisor engine and that the supervisor engine status is good.

Step 4 If the module is not operational, reseat it. If the module is still not operational, contact your customer service representative.


 

Removing the Supervisor Engine


Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051



Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034



Caution To prevent ESD damage, handle supervisor engines by the carrier edges only.

To remove a supervisor engine from a Catalyst 4500 E-series switch, follow these steps:


Step 1 Disconnect any network interface cables attached to the ports on the supervisor engine that you intend to remove.

Step 2 Loosen the two captive installation screws on eithr end of the supervisor engine faceplate.

Step 3 Grasp the left and right ejector levers at either end of the supervisor engine faceplate and simultaneously pivot the levers outward to disengage the supervisor engine from the backplane connector.

Step 4 Grasp the front panel of the supervisor engine with one hand and place your other hand under the carrier to support and guide it out of the slot. Do not touch the printed circuit boards or connector pins.

Step 5 Carefully slide the supervisor engine straight out of the slot, keeping your other hand under the carrier to guide it.

Step 6 Place the supervisor engine on an antistatic mat or in an antistatic bag, or immediately install the supervisor engine in another chassis slot.

Step 7 In chassis configured with redundant supervisor engines, if the chassis slot is to remain empty, you must install a blank line card (C4K-SLOT-CVR-E).


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



 

Attaching Module Interface Cables

The supervisor engine has the following interfaces:

  • USB ports
  • Console port
  • Management port
  • Uplink Ports

USB Port Connections

The USB ports are currently not supported.

Console Port Connection

The console port allows you to access the switch either locally (through a console terminal) or remotely (through a modem). The console is an EIA/TIA-232 asynchronous, serial connection with hardware flow control and an RJ-45 connector.

Management Port Connection

The Ethernet management port can be used (in ROMMON mode only) to recover a switch software image that has been corrupted or destroyed due to a network catastrophe. When using Cisco IOS Release 12.2(50)SG or later, this port can also perform the same functions as the console port. For earlier Cisco IOS software releases, this port is not active while the switch is operating normally.

Uplink Port Connections

The Supervisor Engine 8-E has eight Ethernet uplink ports available on the front panel. The ports can be used provide additional port capacity for a fully configured switch or can reduce the need to use a chassis slot for either a module. The ports can be configured with either SFP transceivers for 1-GB operation or SFP+ transceivers for 10-GB operation. Both transceivers use LC-type connectors (optical) or RJ-45 (copper).


Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021



Note Always keep caps and plugs on the fiber-optic connectors on the cable and the switch when they are not in use.



Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051



Note Make sure that the optical connectors are clean before making the connections. Contaminated connectors can damage the fiber and cause data errors.


Always insert the network connector completely into the socket. A secure connection is especially important when you are establishing a connection between a module and a long distance (1.24 miles) (2 km) network or a module and a suspected highly attenuated network. If the link LED does not light, try removing the network cable plug and reinserting it firmly into the module socket. It is possible that dirt or skin oils have accumulated on the plug faceplate (around the optical-fiber openings), generating significant attenuation and reducing the optical power levels below threshold levels so that a link cannot be made.


Caution Use extreme care when removing or installing connectors so that you do not damage the connector housing or scratch the end-face surface of the fiber. Always install protective covers on unused or disconnected components to prevent contamination. Always clean fiber connectors before installing them.

For installation information, refer to the Cisco SFP and SFP+ Transceiver Module Installation Notes .

Use only Cisco SFP modules on your Cisco device. Each SFP module has an internal serial EEPROM that is encoded with security information. This encoding provides a way for Cisco to identify and validate that the SFP module meets the requirements for the device.

For supported SFP transceiver media types, refer to:

http://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_6982.html

http://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL632702.html

http://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_6981.html

Configuring Your Supervisor Engine

For information and commands to configure your supervisor engine, refer to the software configuration guide for your switch. Configuration guides are located at:

http://www.cisco.com/en/US/products/hw/switches/ps4324/products_installation_and_configuration_guides_list.html

Fiber-Optic Connectors

Fiber-optic cable connectors can be damaged by improper cleaning and connection procedures. Dirty or damaged fiber-optic connectors can result in communication that is not repeatable or inaccurate.

Fiber-optic connectors differ from electrical or microwave connectors. In a fiber-optic system, light is transmitted through an extremely small fiber core. Because fiber cores are often 62.5 microns or less in diameter, and dust particles range from a tenth of a micron to several microns in diameter, dust and any contamination at the end of the fiber core can degrade the performance of the connector interface where the two cores meet. Therefore, the connector must be precisely aligned, and the connector interface must be absolutely free of trapped foreign material.

Connector loss, or insertion loss, is a critical performance characteristic of a fiber-optic connector. Return loss is also an important factor. Return loss specifies the amount of reflected light; the lower the reflection, the better the connection. The best physical contact connectors have return losses greater than –40 dB, although -20 to –30 dB is more common.

The connection quality depends on two factors: the type of connector and the proper cleaning and connection techniques. Dirty fiber connectors are a common source of light loss. Keep the connectors clean at all times, and keep the dust covers installed when the connectors are not in use.

Before installing any type of cable or connector, use a lint-free alcohol pad from a cleaning kit to clean the ferrule, the protective white tube around the fiber, and the end-face surface of the fiber.

As a general rule, whenever there is a significant, unexplained loss of light, clean the connectors.


Caution Use extreme care when removing or installing connectors so that you do not damage the connector housing or scratch the end-face surface of the fiber. Always install protective covers on unused or disconnected components to prevent contamination. Always clean fiber connectors before installing them.

To clean the optical connectors, use a CLETOP cassette cleaner (type A for SC connectors or type B for MT-RJ connectors) and follow the product directions. If a CLETOP cassette cleaner is not available, follow these steps:


Step 1 Use a lint-free tissue soaked in 99 percent pure isopropyl alcohol to gently wipe the faceplate. Wait five seconds for the surfaces to dry, and repeat.

Step 2 Remove any residual dust from the faceplate with clean, dry, oil-free compressed air.


Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051


Step 3 Use a magnifying glass or inspection microscope to inspect the ferrule at an angle. Do not look directly into the aperture. Repeat the process if any contamination is detected.


 

The connectors used inside the system have been cleaned by the manufacturer and connected to the adapters in the proper manner. The operation of the system should be error free if the customer provides clean connectors on the application side, follows the previous directions, and follows these guidelines:

  • Clean the connectors using either a CLETOP cassette cleaner (Type A for SC connectors and Type B for MT-RJ connectors) or lens tissues before connecting to the adapters. Use pure alcohol to remove contamination.
  • Do not clean the inside of the connector adapters.
  • Do not use force or quick movements when connecting the fiber-optic connectors in the adapters.
  • Cover the connectors and adapters to keep the inside of the adapters or the surface of the connectors from getting dirty when you are not using the connectors or while you are cleaning the chassis.

1-Gigabit/10-Gigabit Ethernet Uplink Ports

The 1-Gigabit/10-Gigabit Ethernet uplink ports operate in full-duplex mode only. These ports use the hot-swappable SFP or SFP+ optical transceivers. The SFP transceivers have LC connectors to interface with multimode fiber (MMF) and single-mode fiber (SMF) cable and RJ-45 connectors for the coppoer interfaces.

By default, the Ethernet management port is enabled. The switch cannot route packets from the Ethernet management port to a network port, and from the network port to the Ethernet port. To obtain these, the Fa1 interface is automatically placed in a separate routing domain (or VRF domain), called mgmtVrf. (You observe the ip Vrf forwarding mgmtVrf line in the running configuration when you boot up.)

The specific implementation of Ethernet management port depends on the redundancy model you are applying.
