Table 5.15 lists the ESCON
®
and FICON™ port specifications for the 9900, and Table 5.16 lists
the fibre-channel port specifications for the 9900. Each 9960 subsystem supports up to four
channel adapters and 32 interface ports. Each 9910 subsystem supports up to three channel
adapters and 24 interface ports. Each adapter consists of two cards.
Note: The 8GSE and 8HSE ports are applicable for Hitachi TrueCopy – S/390
®
.
Note: Additional power supplies are needed if three or more channel adapters are installed.
