Installing and Replacing XFP Transceiver Modules

The Cisco NAM 2220 appliance uses one or two 10 GB Ethernet XFP transceiver modules to connect fiber optical cables as data input sources. The XFPs can both be long range or both be short range, or you can install one of each. Depending on the type of XFP you use, you must use the correct fiber optical cables. See Appendix B, "Monitor Port Requirements," for more information.

You install the XFPs into slots on the back panel of the Cisco NAM 2220 appliance. See location #7 in Figure 4-20, Cisco NAM 2220 Appliance Back Panel. The slot on the right is the input to logical DataPort 1 of appliance, and the slot on the left is the input to logical DataPort 2. Figure 4-1 shows a detailed view of an XFP transceiver module installation.

Figure 4-1 Installing an XFP Transceiver Module

XFP positioned for back panel slot


The XFP integrates the receiver and transmit path. The transmit side recovers and re-times the 10 Gbps serial data and passes it to a laser driver. The laser driver biases and modulates a 1310 nm DFB (distributed feedback) laser, enabling data transmission over SMF through an LC connector. The receive side recovers and re-times the 10 Gbps optical data stream from a positive-intrinsic-negative (PIN) photo detector, transimpedance amplifier and passes it to an output driver.

The XFP module uses the bail clasp latching mechanism as shown unlatched in Figure 4-2 and latched in Figure 4-3. See the label on the XFP for technology type and model.

XFP dimensions are:

Height 0.33 inches (8.5 mm)

Width 0.72 inches (18.3 mm)

Depth 3.1 inches (78 mm)

XFP temperature ranges are:

COM—Commercial operating temperature range between 23 degrees Fahrenheit to 158 degrees Fahrenheit (-5 degrees Celsius to 70 degrees Celsius)

EXT—Extended operating temperature range between 23 degrees Fahrenheit it to 185 degrees Fahrenheit (-5 degrees Celsius to 85 degrees Celsius)

IND—Industrial operating temperature range between -40 degrees Fahrenheit to 185 degrees Fahrenheit (-40 degrees Celsius to 85 degrees Celsius)


Caution Do not add labels or markings to the XFPs.

You can order XFPs as hardware options or you can use XFPs you might already own that meet the specifications found in the "XFP Modules" section on page B-1. Because XFPs are delicate devices, they are packaged separately and are not installed in the appliance prior to shipping.

Installing an XFP

To install an XFP into the Cisco NAM 2220 appliance:


Step 1 Locate the XFP you plan to install and remove any protective packaging.

Step 2 Determine into which of the two slots you will install the XFP.

Step 3 With its latch open, slide the XFP into the slot until you feel resistance, then push the XFP harder until you feel (or hear) it click into its socket.

Figure 4-2 shows an example of an XFP with its latch open.

Figure 4-2 XFP (unlatched)

Step 4 With your finger, pull the latch upwards to lock the XFP into its slot.

Figure 4-3 XFP (latched)

The XFP is now ready to receive the fiber optical cable input.


Replacing an XFP

To replace an XFP in the Cisco NAM 2220 appliance:


Step 1 Locate the new XFP you plan to install and remove any protective packaging. Examine the XFP for any signs of damage.

Step 2 Locate the XFP you want to replace on the Cisco NAM 2220 appliance back panel.

Step 3 Remove the fiber optical cable from the XFP.

Step 4 With your finger, pull the latch down to release the XFP from its latched position.

See Figure 4-2.

Step 5 Using the latch, pull the XFP out of the appliance and place it in a safe location.

Step 6 Insert the new XFP into the slot and slide it in until you feel resistance, then push the XFP harder until you feel (or hear) it click into its socket.

Step 7 With your finger, pull the latch upwards to lock the XFP into its slot.

Step 8 Replace the fiber optical cable.


Removing and Replacing a Hard Disk Drive

The Cisco NAM 2220 appliance has six hard disk drives (HDD) installed. The hard drive bay is at the left side of the appliance chassis, underneath the DVD-ROM drive.

Figure 4-4 Cisco NAM 2220 Appliance Front Panel

The hard drive trays in the drive bay are labeled 1, 3, and 5 on the left side of the bay and 0, 2, and 4 on the right side of the bay (see Figure 4-5).

Each of the hard drive trays has two small LEDs. The green LED (lower) indicates the ready and read/write activities of the corresponding disk drive. The amber LED (upper) indicates a fault. There are two other LED indicators on the switch and control panel, near the Power and Reset buttons, that indicate the collective status of all six hard disk drives.

Audible alarms, or beeping tones, also indicate when a hard disk drive fails. For example, a repeating tone that is on for one second, then off for a second, indicates a degraded RAID or Disk Group. The tone remains on during a disk rebuild. After the rebuild completes, an alarm with a different tone sounds.

Hard Disk Configurations

The Cisco NAM 2220 appliance configures the six hard disk drives as two logical RAID disk drives.

Drive 0 and Drive 1 are configured as a RAID1 disk, used to store system images, NAM configuration, and report data.

Unless you experience failures on both RAID1 disk drives, the NAM 2220 system will continue to function due to data redundancy in the RAID1 disk drives. If you should experience a failure on both RAID1 disk drives, you will need to replace both drives, and you must also do a system recovery.

Drive 2 through Drive 5 are configured as a RAID0 disk, used to store capture data.

RAID0 disk drives do no have the data redundancy feature because they are optimized for advantages in disk speed and space. The RAID system automatically detects and skips any bad disk sectors. If any of the RAID0 hard disk drives fail, you will not be able to store or access capture data until you replace the failing drive.


Note A system recovery is not required when you replace a RAID0 disk drive.


Replacing a Hard Disk Drive

When you have to replace a hard drive, you face one of two tasks: replacing a RAID0 disk or replacing a RAID1 disk. Replacing a RAID1 disk is relatively easy. You locate the failing drive, remove it from its tray, drop in a new one, and slide the tray back into the appliance. Replacing a RAID0 disk is a bit more complicated.


Note RAID1 disks (disks 0 and 1) are hot swappable. RAID0 disks (disks 2-5) are not.


Before doing the actual hardware removal and replacement, check the procedures for the type of disk you plan to replace to see when to do the hardware replacement.

Replacing a RAID1 Disk Drive

RAID1 disks drives, disk 0 and disk 1, are hot swappable and do not require you to shut down the NAM appliance.

Replacing a RAID0 Disk Drive

Replacing a RAID0 disk drive requires you to shut down the NAM appliance and temporarily install a VGA monitor, keyboard and mouse.


Note Before you begin, inspect the new disk drive for any signs of damage.


To remove and replace a hard disk drive in the Cisco NAM 2220 appliance:


Step 1 Review the information in the "Safety Warnings" section on page xi and the "Safety Guidelines" section on page 2-2.

Step 2 Power down the appliance and all external devices. Disconnect the AC power cord source and all external cables.

Note This step is not required if you are replacing a RAID0 disk, disk 0 or 1.

Step 3 Attach the antistatic wrist strap to your wrist and connect its cord to the ESD socket on the top, left-hand side on the front of the appliance.

Step 4 Select the drive bay where you want to replace the drive.

Step 5 Remove the drive tray by pressing the blue button to open the lever and pull the tray out. (See location 1 in Figure 4-5.)

Step 8 Press the lever until it snaps shut to secure the drive into the drive bay.


Replacing a RAID1 Disk Drive

This procedure describes how to replace a failing RAID1 disk drive when one of the two hard disk drives in a RAID1 configuration has failed. You can perform a hot swap of the failing drive while the Cisco NAM 2220 appliance continues to run.


Warning Remember to use an ESD or antistatic wrist strap, a conductive foam pad or mat (recommended), and follow all necessary antistatic standards when handling the hard disk drives.



Step 1 Identify the failing disk drive by checking the LED status indicators.

An amber LED on indicates a failing disk drive.

Step 2 Remove the failing disk drive.

See Replacing a Hard Disk Drive for detailed information about removing and replacing a disk drive.

Step 3 Replace the failing disk drive in the disk tray with a new working disk drive, or replace the disk tray with a new disk tray with a good working disk drive.


Note The Cisco part number for the Cisco NAM 2220 appliance disk drive is NAM2220-HDD-6X146G.


See Replacing a Hard Disk Drive for detailed information about removing a disk drive.

Step 4 The RAID disk rebuild process will start automatically after few seconds. If the rebuild process does not start after a minute, try removing and inserting the disk tray again.

The entire rebuild process might take several hours. During the rebuild, the audible alarm (a mild off-on tone) will be on. The amber LED on the replaced disk might also continue to blink, but should be off after the rebuild process completes.


Note Do not reboot the Cisco NAM 2220 appliance until the rebuild process completes.



Replacing a RAID0 Disk Drive


Note This procedure requires you to temporarily attach a VGA monitor, keyboard, and mouse to your Cisco NAM 2220 appliance.


If any of the four hard disk drives in the RAID0 configuration fail, the Cisco NAM 2220 appliance will not be able to write or access capture data.

Please follow all necessary antistatic standards in handling the hard disk drives.


Warning Remember to use an ESD or antistatic wrist strap, a conductive foam pad or mat (recommended), and follow all necessary antistatic standards when handling the hard disk drives.


To replace a RAID0 hard disk drive:


Step 1 Identify the failing disk drive by checking the LED status indicators.

An amber LED on indicates a failing disk drive.

Step 2 Shut down NAM 2220 using the CLI shutdown command.

Step 3 Remove the failing disk drive.

Installing or Replacing a Power Supply

The Cisco part number for a Cisco NAM 2220 appliance power supply is NAM2220-AC-PS.


Caution Your Cisco NAM 2220 appliance does not have a redundant power supply unless you have purchased an optional second power supply. If there is no second power supply, before replacing an existing power supply, you must first take the appliance out of service. To do so, turn off all external devices connected to the appliance, turn off the appliance by pressing the power button, and unplug the AC power cord.

Figure 4-20 Cisco NAM 2220 Appliance Back Panel

The Cisco NAM 2220 appliance can be equipped with one or two AC power supplies. If you have two AC power supplies, the power supplies create redundancy for the appliance, enabling one to become a backup for the other in case of failure.

Redundant power supplies also enable you to "hot-swap" a power supply, if you need to replace it. In other words, you can replace a power supply while the appliance is running. To maintain hot-swap capability, make sure that there is an active power supply in both appliance slots before replacing (hot-swapping) a power supply.

The AC power supplies are accessible from the rear of the appliance. If the appliance is equipped with only one power supply, the space next the module is occupied with a blank filler panel. See location 11 in Figure 4-20.


Caution If only one power supply is installed, it must be in the right-hand slot and a power supply blank filler panel must be installed in the left-hand slot to ensure proper cooling.

This section includes the following topics

Replacing a Redundant Power Supply

Replacing a Nonredundant Power Supply

Adding a New Redundant Power Supply

Replacing a Redundant Power Supply

If you have two power supplies installed in your Cisco NAM 2220 appliance, one of the modules is redundant, enabling you to hot-swap one of the power modules (replace a module without powering down the system), if you need to replace one of the power supplies.

To replace a redundant power supply:


Step 1 Check the status LED on the power supplies (see location 2 in Figure 4-21) to determine which power supply has failed.

Step 2 Disconnect the appropriate AC power source.

Step 3 Press and hold the green safety lock (see location 1 in Figure 4-21) downward to disengage the power supply.

Step 4 Grasp the handle (see location 3 in Figure 4-21) and pull the power supply from the appliance chassis.

Step 5 Slide the new power supply into the appliance chassis until it clicks into place.


Replacing a Nonredundant Power Supply

If your Cisco NAM 2220 appliance has a single power supply, you can replace that power supply only when the appliance is safely powered down.

To replace a nonredundant power supply module:


Step 1 Turn off all external devices connected to the appliance, turn off the appliance by pressing the power button, and unplug the AC power source.

Step 2 Press and hold the green safety lock (see location 1 in Figure 4-21) downward to disengage the power supply.

Step 3 Grasp the handle (see location 3 in Figure 4-21) and pull the power supply from the appliance chassis.

Step 4 Slide the new power supply into the appliance chassis until it clicks into place.


Adding a New Redundant Power Supply


Note When adding a redundant power supply to a Cisco NAM 2220 appliance, the additional power supply must be the same type as the existing power supply.


To add an additional power supply module to an appliance that has a single power supply:


Step 1 Remove the blank filler panel from the rear panel by pressing the two release tabs toward each other (see location 1 in Figure 4-22).

Step 2 Pull the blank filler panel from the appliance chassis.

Step 3 Slide the new power supply into the appliance chassis until it clicks into place.

Step 4 Save the blank filler panel, in case you need to use it at a later date.


Mounting the Cisco NAM 2220 Appliance in a 2-Post Rack

Typically, the Cisco NAM 2220 appliance mounts to a 19-inch (48.3-cm) 2-post equipment rack with rack-mounting brackets that attach to the front sides of the appliance. The inside width between the two posts or mounting strips (left and right) must be at least 17.5 inches (44.45 cm). See the "Preparing Your Site for Installation" section on page 2-6 for information about the types of equipment racks.

Even though the intake and exhaust for cooling air are located on the front and on the rear of the appliance, respectively, it is recommended that multiple appliances be stacked in a rack with at least a 1.5-inch (3.81-cm) vertical clearance.


Caution To prevent damage to the appliance, only use Cisco provided hardware and screws when installing the appliance.

To secure the appliance to the equipment rack, you must use the two 10-32 x 1/2-inch rack screws (see Figure 4-23 and Table 4-2) for each side or follow your local practices for installing the appliance into your equipment rack. Ensure that the rack-mount brackets have been securely fastened. See the "Attaching the L Brackets to the Appliance" section for more information.

The following procedure provides a general outline for mounting the appliance into the equipment rack.


Caution To prevent injury, review the "Safety Guidelines" section on page 2-2 and the "Rack-Mounting Configuration Guidelines" section on page 3-3 before installing the appliance in the equipment rack.


Step 1 Locate the equipment rack position you plan to install the appliance into.

Step 2 Verify that there are no obstructions and ensure that the equipment rack is stabilized.

Step 3 Position the appliance in the equipment rack, lining up the bracket holes on the appliance with the holes on the rack, and secure it with two 10-32 x 1/2-inch rack screws (each side). You need two people to install the appliance in the rack—one person to hold the appliance and one person to secure it to the rack.


Note The vertical spacing for the equipment rack is at least 1.75 inches (4.44 cm), with mounting holes spaced 1.5 inches (3.81 cm) apart.


Step 4 Tighten the screws using a Number 2 Phillips screwdriver (each side).

Step 4 You are now ready to install the appliance into the 2-post rack.


Proceed to the next section, "Installing the Appliance in the Rack," to continue the installation.

Installing the Appliance in the Rack


Caution Lifting the appliance and attaching it to the rack is a two-person job. If needed, use an appropriate lifting device. A fully loaded Cisco NAM 2220 appliance weighs approximately 51.5 lb (23.4 kg).

Before you begin, check the 10-32 x 1/2-inch screws that are included in the 2-post rack-mount kit (see Table 4-2) to see if they are the correct size for your rack. If not, obtain the correct screws to use in the procedure where "rack screws" are required.

To mount the appliance in the rack:


Step 1 Locate one person at the front of the rack and one at the rear.

Step 2 Position an L bracket on the front side of the center post (see Figure 4-25).

Figure 4-25 Attaching an L Bracket to a Center Post

Step 3 Attach the L bracket to the center post using the 10-32 x 1/2-inch rack screws (see Figure 4-25). Do not fully tighten the screws at this time.

Step 4 Repeat Steps 2 and 3 for the other L bracket.

Step 5 Tighten all the 10-32 x 1.2-inch rack screws on both sides of the rack.
