Port to Device Cabling

Cabling for UPS and Disc Arrays

There are three UPS cabling solutions for the EISA/PCI MUX:

1. For the RJ45 type MUX (J2484A port module or the 8 port MUX

card), use a “EISA MUX to HP-PB MUX” converter cable; J2489A

RJ45-HP/DB25 converter (J3830-60010) and the default DB25

(5061-2569) UPS cable or the default DB25 cable for disc array.

2. For the DB25 type MUX (J2485A), a new cable ordered as option 022

with the UPS products, may be used to directly connect to PCI/EISA

MUX DB25 type port module.

3. Alternatively, for the DB25 type MUX (J2485A), it requires a NULL

Modem converter of DB25F to DB25M, crossing pins 2 and 3 (receive

and transmit), and straight through on pin 7. For the UPS

application, only pins 2, 3 and 7 are required.
