Removing the PVDM4 from the Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Module in the Cisco ISR 4451-X


Step 1 Shut down the electrical power to the slot in the router by either turning off the electrical power to the router or by issuing the online insertion and removal (OIR) stop command. Leave the power cable plugged in to channel ESD voltages to ground. For more information on OIR, see the “OIR Procedures” section.

Step 2 Loosen the two captive screws on the network interface module

Step 3 Remove the network interface module with the PVDM4. (See Figure 6-22.)

Step 4 Loosen the three screws and standoffs on the PVDM4.

Step 5 Lift the PVDM4 up from the network interface module.

Step 6 Place the PVDM4 in an anti-static bag.

Step 7 If you are not immediately replacing the network module, install the blank cover over the empty network module slot.

Step 8 Slide the network interface module back in the router and tighten the captive screws.


 

Removing and Replacing the USB Flash Token Memory Stick

The Cisco ISR 4451-Xs contain ports for a 1 GB flash token memory stick to store configurations or Cisco IOS XE consolidated packages.


Note Only Cisco USB Flash memory modules are supported by Cisco routers.



Caution Do not remove a USB Flash memory module when issuing some file access command or a read/write operation to the Flash memory module when it is processing. The router might reload or the USB Flash memory module can be damaged. You can check to see if the USB activity LED on the Cisco ISR 4451-X front panel is flashing, prior to the removal of the USB device

To remove and then replace a USBflash token memory stick from a Cisco ISR 4451-X, follow these steps:


Step 1 Pull the memory stick from the USB port.

Step 2 To replace a Cisco USB Flash memory stick, simply insert the module into the USB port 0 or 1 port as shown in Figure 6-23. The Flash memory module can be inserted in only one way, and can be inserted or removed regardless of whether the router is powered up or not.


Note Figure 6-23 is only a sample of how the memory stick is inserted into the port and does not display the actual Cisco ISR 4451-X faceplate.


Figure 6-23 Cisco ISR 4451-X Flash Token Memory Stick

 


Note You can insert or remove the memory stick whether the router is powered on or not.



 

This completes the USB Flash memory installation procedure.

Replacing Power Supplies and Redundant Power Supplies

The Cisco ISR 4451-Xs have replaceable power supply modules and some have an optional external redundant power supply (RPS). All of the internal power supplies for the Cisco ISR 4451-Xs are modular and do not have internal cabling. These modular power supplies can be removed or installed using only a screwdriver.

Replacing the Cisco ISR 4451-X Power Supply


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



Warning This unit might have more than one power supply connection. All connections must be removed to de-energize the unit. Statement 1028



Warning Care should be taken while removing the power supplies and power inverters (especially in boost mode of operation). If the total power consumption is higher than can be supported by one power supply alone and in this condition a power supply is removed, the hardware can be damaged. This may then result in the system being unstable or unusable.


All of the power supply and RPS options have a similar modular form factor, with no cabling, for easy removal and replacement. If an RPS is attached, the power supply may be hot-swapped.

Replacing the Power Supply on the Cisco ISR 4451-Xs


Caution Care should be taken while removing the power supplies and power inverter, especially in boost mode of operation. If the total power consumption is higher than can be supported by one PSU alone, and in this condition, if a PSU is removed, the hardware can be damaged. This may result in the system being unstable or unusable.
Similarly if there is only one PoE converter and it is providing PoE power to an SM, in this condition if the PoE inverter is removed, the hardware may be damage and may result in the system being unstable or unusable.


Step 1 Read the “Safety Warnings” section section and disconnect the power supply before you perform any module replacement.

Step 2 Pull on the quick-release catch on the side to leverage the power supply from its connector, and then slide the power supply module out of the chassis.

Step 3 Insert the replacement power supply module.

Inserting PoE Supply in an Ethernet Switch Network Module

To insert a PoE PSU, you must first remove the fan tray. For instructions on how to remove the fan tray, see “Replacing the Cisco ISR 4451-X Fan Tray” section

The PoE power supply for Ethernet Switch Network Modules supports online insertion feature. The PoE power supply does not support online removal.


Warning Care should be taken while removing the power supplies and power inverters (especially in boost mode of operation). If the total power consumption is higher than can be supported by one power supply alone and in this condition a power supply is removed, the hardware can be damaged. This may then result in the system being unstable or unusable.


The following messages are expected behavior when you try to reload or insert a PoE supply in a router with Ethernet Switch Network Module:

Aug 10 18:29:40.331: %ILPM_FAULT-5-ILPM_NOTICE: Notice: Inline power supply is being started.
*Aug 10 18:29:40.331: %ILPM_FAULT-5-ILPM_WARNING: Warning: Ethernet Switch Network Modules with PoE Support need to be reloaded to function properly.
*Aug 10 18:29:40.691: %SYS-5-RESTART: System restarted -- Cisco IOS Software, C2900 Software (C2900-UNIVERSALK9-M), Version 15.0(1)M2, RELEASE SOFTWARE (fc2)
 

This warning message is not an indication of any error in the system but a warning upon system reload or PoE power supply restoration.

Upon PoE power supply insertion, inline power supply restores automatically in the router. After the insertion, resets are needed for the switch modules in the router for the PoE supply to work properly.

If there are two PoE supplies, the power supplies can operate in a boost mode or redundant mode. In a boost mode, the total power supplied is a sum of the two power supplies capacity. In a redundant mode, if one of the PoE supply fails, the other PoE will supply power.

Cisco ISR 4451-X Power and RPS Error Messages

There are several RPS error messages unique to the Cisco ISR 4451-Xs. The messages appear on the router console terminal.

Replacing a Fan Tray

The Cisco ISR 4451-Xs have hot-swappable fan trays that are field replaceable units (FRUs). The fan tray includes all of the router fans in one assembly. If a fan fails, replace the tray using a flat-blade or Phillips screwdriver.

Before Hot-Swapping a Fan Tray

Before hot-swapping a fan tray, read the safety precautions below.

  • Read the entire procedure and have the required tools available.
  • Do not attempt the hot-swap in ambient air temperature above 90°F (32°C).
  • Do not attempt the hot-swap at an altitude above 6000 feet (1829 meters).
  • When the router is being operated, it is recommended to change the fans in the Cisco ISR 4451-X within 2 minutes to ensure the router does not overheat:

Removing and Installing a CompactFlash Memory Card

This section describes installing and replacing CompactFlash (CF) memory cards in Cisco ISR 4451-Xs. It contains the following sections:


Note You must turn off the power supply to the router to replace a CompactFlash Memory card. A CompactFlash memory card must be inserted in order to run a Cisco IOS XE software image.


Preventing Electrostatic Discharge Damage

CF memory cards are sensitive to electrostatic discharge (ESD) damage, which can occur when electronic cards or components are handled improperly. ESD results in complete or intermittent failures.

To prevent ESD damage, follow these guidelines:

  • 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.
  • Place CF memory cards on an antistatic surface or in a static shielding bag. If the card will be returned to the factory, immediately place it in a static shielding bag.
  • Avoid contact between the card and clothing. The wrist strap protects the card from ESD voltages on the body only; ESD voltages on clothing can still cause damage.
  • Do not remove the wrist strap until the installation is complete.

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

Removing a CompactFlash Memory Card

To remove a CF memory card from the chassis, perform the following steps:


Caution Do not remove a CF memory card from the chassis while it is being accessed. Cisco recommends not removing the CF when in Cisco IOS-XE at all. Either power the system off or fall back to the rommon prompt, if removing the CF. .


Step 1 Read the “Safety Warnings” section section and disconnect the power supply before you perform any module replacement.

Step 2 Remove the fan tray. For instructions on removing the fan tray, see “Replacing the Cisco ISR 4451-X Fan Tray” section.

Step 3 Remove the CF cover by placing a flat-blade screwdriver in the slot and pushing sideways against the tensioner to release the cover door.

 

Step 4 Press the ejector button next to the CompactFlash memory card. The ejector button moves outward so that it projects from the panel.

 

Step 5 Press the ejector button again. This ejects the CompactFlash memory card partially out of its slot.

Step 6 Pull the CF memory card out of its slot.

Step 7 Push the ejector button in until the button is flush with the bezel.


Caution To prevent damage to the ejector mechanism, the ejector button must remain pressed all the way in (flush against the bezel) when not being used to eject a CompactFlash memory card.

Step 8 Replace the fan tray.


 

Installing a CompactFlash Memory Card

To install a CompactFlash memory card, perform the following steps:


Step 1 Read the “Safety Warnings” section and disconnect the power supply before you perform any module replacement.

Step 2 Remove the fan tray. For instructions on removing the fan tray, see “Replacing the Cisco ISR 4451-X Fan Tray” section.

Step 3 Make sure that the ejector button is fully seated until it is flush with the bezel.


Note If the ejector button is projecting out from the panel, push it in until it is flush with the bezel.


Step 4 Insert the CompactFlash memory card into the slot until it is fully seated. The ejector button remains flush with the panel.


Note If the ejector button is projecting from the panel after you insert the CompactFlash memory card, remove the CompactFlash memory card, press the ejector button until it clicks, and reinsert the CompactFlash memory card.



Caution To prevent damage to the ejector mechanism, the ejector button must remain fully seated when not being used to eject a CompactFlash memory card.

Step 5 Replace the CompactFlash cover by inserting the cover lip into the chassis and pushing the cover to snap it back into place.

Step 6 Replace the fan tray.


 

Installing SFP Modules

This section describes how to install optional small-form-factor pluggable (SFP) modules in Cisco ISR 4451-Xs to provide optical Gigabit Ethernet connectivity. There are four SFP slots in the Cisco ISR 4451-X.

The SFP module installs into a slot on the router rear panel. When selected in Cisco IOS software, it is assigned port gigabitethernet 0/0/0 . The default is the built-in RJ-45 1000Base-T connector, which is enabled on this port.

Only SFP modules certified by Cisco are supported on Cisco ISR 4451-Xs. Table 6-3 lists supported SFPs on Cisco ISR 4451-Xs.
