  • Page 99 Hot-Swapping Hardware Components Memory Card Read-Write Protect Switch Memory cards are read-write protected. To change the protection on a memory card, you must physically remove the card from the BayStream hardware, change the protection, and reinsert the card. Failure to adhere to this sequence can cause unpredictable and undesirable consequences.

    Hot-Swapping Hardware Components Protecting Memory Card Files Bay Networks ships each memory card with its Read-Write Protect switch in the unprotected position (Figure 5-2). After successfully loading the configuration file and saving your configuration, you may want to write-protect the memory card for backup purposes.

    Hot-Swapping Hardware Components Caution: While the PCMCIA SRAM card is installed in a BayStream hardware platform, there is no drain on the 3-V lithium battery. Battery drain occurs only when the PCMCIA SRAM card is removed from the BayStream platform. To ensure data integrity, we recommend that the battery be replaced yearly.
  • Page 104 Installing and Maintaining BN Platforms When removing or installing a link module, keep the following in mind: • If you replace a link module with another of a different type (that is, you replace an Ethernet link module with an FDDI link module), you must first undo the configuration of all circuits on the old slot before the hardware platform software can properly configure the new module.

    Hot-Swapping Hardware Components • Before removing or installing a module, you must first access the interior of your hardware platform. (Refer to Chapter 4, “Accessing the Interior,” for instructions.) Caution: Electrostatic discharge can damage hardware. Use the antistatic wrist strap when handling any hardware platform components. The procedures for replacing a routing engine processor module or an SRM-F are the same for the BLN, BLN-2, and BCN with one exception: you must first remove a board retainer bracket from the BLN or BLN-2 in order to gain access to...
