Overview

• For general information on HP ESCON PA microcode, refer to the “HP ESCON PA Microcode

Overview” section on page 12. For specific instructions to configure the Cisco IOS software to

download microcode from the router Flash memory card or SanDisk memory device, refer to the

“Upgrading the HP ESCON PA Microcode from Cisco.com” section on page 33.

ESCON Specifications

Table 1 lists the specifications for the ESCON interfaces.

LEDs

The functions of the HP ESCON PA LEDs are as follows:

• Enabled—Indicates that the HP ESCON PA is enabled for operation by the system.

• Present—Indicates that the ESCON channel is detected by the HP ESCON PA.

• Loaded—Indicates that the ESCON channel firmware is completely loaded.

• Signal—Indicates that the sync signal has been detected from the ESCON neighbor node.

• Online—Indicates that an establish-logical-path request has been received from the channel and that

the establish-logical-path request matches one of the paths configured on the HP ESCON PA.

Characteristic ESCON Specification

Supported processor I/O architectures ESA/390

Bit transmission Serial

Maximum distance (for LED with

ESCON)

1.9 miles (3.1 km) point-to-point

5.7 miles (9.2 km) with two ESCON Directors and each hop

not exceeding 3 km.

Channel data rate Up to 17 MBps

Signaling rate 200 Mbps

Cable types Fiber-optic (62.5/125 micron multimode)

Addition of devices to running systems Dynamic

Number of addressable devices per

channel

256 x 16 x 16 x 253

Connectable control units per channel Up to 59 (through a 9032 ESCON Director)

Connectable channels per adapter Up to 59 (through a 9032 ESCON Director); varies by

control unit

1. The HP ESCON PA requires dynamic = NO with HCD.

2. Where 256 represents available unit addresses, 16 represents the number of logical partitions (LPARs), 16 represents the

number of control unit images, and 253 represents the number of ESCON director paths. It is unlikely a system would have

the resources to support the total number of available addresses.
