Installation Guide for fl Modules 2007-02

ProCurve Switch fl Modules
• The ports on the Gigabit-SX and Gigabit-LX LC mini-GBICs installed
in the10-Port Mini-GBIC Interface Module are compatible with IEEE
802.3z Gigabit-SX and Gigabit-LX standards, respectively.
• The transceiver ports on the X2 10GbE Interface Modules (J8736A
and J8737A) are compliant with X2 and XENPAK MSAs, and are
compatible with the IEEE 802.3ak CX4 and IEEE 802.3ae XAUI
industry standards.
Hot Swapping and Redundancy
All modules can be “hot swapped”; that is, they can be removed or installed
while the switch is powered on. However, note the following differences
between module types with respect to redundancy:
■ When the primary switch fabric module fails, the redundant switch fabric
module takes over (in less than five seconds) and continues to function
as the primary module even after the failed module is replaced.
■ When the primary management module fails, the redundant management
module takes over immediately as the new primary management module.
However, this new primary management module will reboot the other
modules resulting in a loss of traffic until all modules are back on line.
When the failed management module is replaced, the replacement
management module serves as the redundant management module.
■ Interface modules do not have redundant protection. If an interface
module fails, traffic on the module will stop until you can replace the
module.
■ When hot swapping interface and switch fabric modules, use the CLI
redundancy switchover fabric-module lock command to prevent a redundant
switch fabric module from taking over as the primary switch fabric
module. Once the hot swap is completed, re-enable fabric protection
switching by using the redundancy switchover fabric-module clear command
■ When hot swapping modules, it is recommended that you use the CLI
power down and power up commands on the slot where the module is
inserted. This will help maintain a consistent inventory of modules in the
system.
Fail Over Protection
If the primary management module fails, the redundant management module
will reboot the switch fabric module and interface modules. During this time,
service is affected.
