interface module (eight ports) is the same as that of an 8 Gbit/s Fibre Channel
interface module (eight ports).
Impact on the System
During the replacement of an 8 Gbit/s Fibre Channel interface module (eight
ports), the system switches services from this module (8 array ports) to other
ports on this controller or on the peer controller. If available links are unable to
bear the current service load, host latency increases and the system performance
degrades. If there are no redundant links, services carried by the 8 Gbit/s Fibre
Channel interface module (eight ports) will be interrupted.
Prerequisites
● A spare part is on hand.
● The 8 Gbit/s Fibre Channel interface module (eight ports) that you want to
replace has been located.
You can locate a component in either of the following ways:
● Locating a component based on alarms in DeviceManager: On the Alarms and Events
page of DeviceManager, view the help information and determine the ID of the
component to be replaced. Then locate the component at your site based on its ID.
● Locating a component based on the status of its Running/Alarm indicator: For details
about the indicators on
dierent components, see Indicator Introduction of each
component in the
Product Description
specic to your product model and version.
● Services running on the interface module that you want to replace have been
stopped.
● The cable connection positions of the interface module that you want to
replace are labeled on the cables.
Precautions
● Remove the optical module from the 8 Gbit/s Fibre Channel interface module
(eight ports) that you want to replace. Insert the new 8 Gbit/s Fibre Channel
interface module (eight ports) in the controller enclosure. After the Power
indicator stays green, insert the removed optical module in the new 8 Gbit/s
Fibre Channel interface module (eight ports).
● Remove and insert an 8 Gbit/s Fibre Channel interface module (eight ports)
with even force. Excessive force may damage the appearance or connectors of
the interface module.
● An 8 Gbit/s Fibre Channel interface module (eight ports) must be replaced
within
ve minutes. Otherwise, the system heat dissipation is compromised.
● After you remove the old 8 Gbit/s Fibre Channel interface module (eight
ports), wait 15 seconds before inserting the new one.
● There are eight links connecting to an 8 Gbit/s Fibre Channel interface
module (eight ports). If you want to replace the 8 Gbit/s Fibre Channel
interface module (eight ports), ensure that all working links have backup
links. You are advised to disable the ports of the switch that connect to the 8
Gbit/s Fibre Channel interface module (eight ports) and switch the services on
these ports to backup links to avoid interruption during the replacement.
