Battery specifications
The CP card has a lithium carbon-monoflouride coin cell battery type Rayovac BR1225,
specification
3.0 volt, 50 mAh.
WARNING! Do not attempt to replace the real time clock (RTC) battery on the CP card. There is
danger of explosion if the battery is incorrectly replaced or disposed of. Contact HP Technical

Serial port specifications
Each CP card provides a three-wire terminal serial port (labeled 10101) that has a “DB-9” male
connector and an RS-232 signal subset.
NOTE: To provide dust and ESD protection, keep the cover on the serial port whenever the port is
not in use. The terminal serial port is intended primarily for use during the initial setting of the IP
address and for service purposes
The serial port can be used to connect to a computer workstation or terminal without connecting to
the fabric. The terminal device should be configured to 9600 baud, 8 data bits, no parity, 1 stop
bit, with no flow control.
A 10 ft. (3.0 m) serial cable is provided with the switch; it can be converted from a DB-9 serial cable
to an RJ-45-style serial cable by removing the adapter on the end of the cable.
The terminal serial port requires a straight-through serial cable with a female 9-pin subminiature-D
connector. Use the pinouts listed in Table 55.
