  • The color coding of the DC input power supply leads depends on the color coding of the DC power source at your site. Ensure that the lead color coding you choose for the DC input power supply matches the lead color coding used at the DC power source and verify that the power source is connected to the negative (–) terminal and to the positive (+) terminal on the power supply.

  • Ensure that the chassis ground is connected on the chassis before you begin installing the DC power supply. Follow the steps provided in the Chassis Grounding .


Warning

Statement 1003—DC Power Disconnection

To reduce risk of electric shock or personal injury, disconnect DC power before removing or replacing components or performing upgrades.

Prepare the wire for connecting to the DC power supply

In the Cisco 8300 Series Secure Routers, the DC power supply has a terminal block that is installed into the power supply terminal block header.

Use these steps to prepare the wire for connection to the terminal source:

Procedure

Step 1

Turn off the circuit breaker from the power source to be connected to the power source. Ensure the wires to be attached to the power supply are not energized.

Step 2

The wires connecting to the power supply can be stripped back and terminated directly to the power supply terminal block. Alternately a crimp style spade terminal lug can be attached to the end of the wire. If using a terminal lug, follow the manufacturer's instructions for terminating the lug to the wire. If terminating directly to the terminal block using bare wire, following the directions shown below.

Use a wire-stripping tool to strip each of the two wires coming from the DC input power source to approximately 0.39 inch (10 mm) +/- 0.02 inch (0.5 mm). It is recommended that 14 AWG insulated wire be used. Do not strip more than the recommended length of wire because doing so could leave the wire exposed from the terminal block and shows a stripped DC input power source wire.

Figure 17. Stripped DC input power source wire

Warning

Statement 1008—Class 1 Laser Product

This product is a Class 1 laser product.


Note

We recommend that you wait 30 seconds between removal and insertion of an SFP on an interface module. This time is recommend to allow the transceiver software to initilize and synchronise with the standby RSP. Chaning an SFP more quickly could result in transceiver initialization issues that disable the SFP

  • Do not remove the dust plugs from the SFP and SFP+ modules or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module ports and cables from contamination and ambient light.

  • Removing and installing an SFP and SFP+ module can shorten its useful life. Do not remove and insert any SFP/SFP+ module more often than is necessary.

  • To prevent ESD damage, follow your normal board and component handling procedures when connecting cables to the switch and other devices.

  • When you insert several SFP and SFP+ modules in multiple ports, wait for 5 seconds between inserting each SFP/SFP+. This will prevent the ports from going into error disabled mode. Similarly, when you remove an SFP and SFP+ from a port, wait for 5 seconds before reinserting it.

Procedure

Step 1

Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface.

Step 2

Find the send (TX) and receive (RX) markings that identify the top of the SFP/SFP+ module.

On some SFP/SFP+ modules, the send and receive (TX and RX) markings might be shown by arrows that show the direction of the connection.

Step 3

If the SFP/SFP+ module has a bale-clasp latch, move it to the open, unlocked position.

Step 4

Align the module in front of the slot opening, and push until you feel the connector snap into place.

Step 5

If the module has a bale-clasp latch, close it to lock the SFP/SFP+ module in place.

Step 6

Remove the SFP and SFP+ dust plugs and save.

Step 7

Connect the SFP and SFP+ cables.

Remove and install an M.2 USB|NVMe module

This section describes installing and replacing an M.2 USB|NVMe module on the Cisco 8300 Series Secure Routers.

Prevent electrostatic discharge damage

The M.2 module is 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 the M.2 storage devices on an anti-static surface or in a static shielding bag. If you have to return the device to the factory, immediately place it in a static shielding bag.

  • Avoid contact between the device and clothing. The wrist strap protects the device 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 anti static strap. The measurement should be between 1 and 10 megohms (Mohms).

Managing self encrypting drives

Cisco 8300 Series Secure Routers support self-encrypting drives (SED), which helps to enhance the security of data that are stored on these platforms. SEDs are locked using a security key. The security key, which is also known as Key-Encryption Key or an authentication passphrase is used to encrypt the media encryption key. If the disk is not locked, no key is required to retrieve the data. To enable the security lock, use the hw-module harddisk security-lock enable to enable the command. To disable the security lock, use the no hw-module harddisk security-lock enable command.

Also, you can perform these actions:

  • To check the security status, use the show hw-module harddisk security-lock status command.

  • To perform factory reset on the SED when the security-lock is enabled, use the factory-reset sed

  • To perform factory reset on the SED without checkig the status of the security-lock, use the factory-reset sed PSID command. The PSID (Physical Secure ID) is a 32 character ASCII string read from the label attached to the SED drive.
