Operating the Core Switch 2/64
91 Core Switch 2/64 V4.1 Installation Guide
Operating Information for System Components
The Core Switch 2/64 includes two logical switches: one for any port cards in
slots 1-4, and one for any port cards in slots 7-10. The port cards can be installed
in any combination of slots 1-4 (switch 0) and 7-10 (switch 1).
The active CP card controls both logical switches.
Port Cards
Caution: Wear a grounded ESD strap when handling a port card. A
grounding connection is available on the chassis above the power
connectors.
To ensure correct cooling of the chassis and provide protection from dust,
install a filler panel in any slots that do not contain a port card.
Disassembling any part of a port card voids the part warranty and regulatory
certifications. There are no user-serviceable parts inside the port card.
Each port card provides 16 auto-sensing Fibre Channel ports, capable of
auto-sensing data transmission speeds of 1 and 2 Gbps.
The ports on each of the port cards are color-coded to indicate which ports can be
used in the same ISL Trunking group: four ports marked with black solid ovals
alternate with four ports marked with oval outlines. An illustration of the Port
Card is provided in
Figure 22 on page 103.
Note: ISL Trunking is a Fabric OS feature that enables distribution of traffic over the
combined bandwidth of up to four ISLs between two directly adjacent switches, while
preserving in-order delivery. For more information, refer to the
HP StorageWorks ISL
Trunking Version 3.1.x/4.1.x User Guide
.
The switch can continue to operate while a port card is being replaced, but any
devices connected to the port card must be disconnected. To ensure correct air
circulation inside the switch and provide protection from dust, filler panels can be
ordered for any empty slots.
