The switch can continue to operate while a 16-port card is replaced, but any devices connected to the 16-port card must be disconnected. To determine the status of a 16-port card: 1. Check the LED indicators on the 16-port card. Refer to Table 5 on page 56 for LED interpretation. 2. Check 16-port card status using the slotShow command. For additional information about this command, refer to the hp StorageWorks fabric os reference.

Disassembling any part of a CP card voids the part warranty and regulatory certifications. There are no user-serviceable parts inside the CP card. There are two CP cards, an active CP card and a standby CP card. The active CP card is the one actively controlling the HP StorageWorks Core Switch 2/64. If the active CP card fails or is uninstalled, the standby CP card automatically becomes the new active CP card. Failover occurs as soon as the active CP card is detected to be faulty or uninstalled.

For information about commands and whether they can be entered through the active or standby CP card, refer to the hp StorageWorks fabric os reference. Each CP card provides the following ports: • Modem serial port The modem serial port has an RS-232 connector wired as a DTE device and is designed to connect to a DCE device, such as a modem. • Terminal serial port (also known as a console port) The terminal serial port has an RS-232 signal subset connector that can be used to connect to a PC serial port or dumb terminal.

CAUTION
To prevent damage to the electrical components, wear an ESD
grounding strap when working with the CP card.
Disassembling any part of a CP card voids the part warranty and regulatory
certifications. There are no user-serviceable parts inside the CP card.
There are two CP cards, an active CP card and a standby CP card. The
active CP card is the one actively controlling the HP StorageWorks Core
Switch 2/64. If the active CP card fails or is uninstalled, the standby CP
card automatically becomes the new active CP card. Failover occurs as
soon as the active CP card is detected to be faulty or uninstalled.
Information about both CP cards, including which card is active, is
available through the
haShow
command. For information about commands
and whether they can be entered through the active or standby CP card,
refer to the
hp StorageWorks fabric os reference
.
Each CP card provides the following ports:
•
Modem serial port
The modem serial port has an RS-232 connector wired as a DTE device
and is designed to connect to a DCE device, such as a modem.
•
Terminal serial port (also known as a console port)
The terminal serial port has an RS-232 signal subset connector that can
be used to connect to a PC serial port or dumb terminal.
