A single security device can support a 10/100Base-T and GBIC card simultaneously;
however, the cards are not hot-swappable.
10/100 Mbps
The 10/100 Mbps interface module is typically used to support a 10Base-T or 100Base-T
LAN. The card can support 2, 4, or 8 copper interfaces, and uses RJ–45 connectors with
twisted pair.
NOTE: The ISG2000 supports a maximum port count of 28. When using
8-port 10/100–Mbps modules in each I/O slot, ports five through eight in slot
4 are automatically disabled. You cannot configure these ports for firewall
or HA functionality.
10/100/1000 Mbps
The tri-mode card, available for ISG security devices, is a 2 Ethernet port
10/100/1000–Mbps I/O card. The card supports 2 copper interfaces, uses RJ–45
connectors and twisted pair, and contains the following I/O port configurations:
10–Mbps full/half duplex
100–Mbps full/half duplex
1000–Mbps full duplex
Auto (autonegotiate link speed/duplex)
The fiber interface module provides connectivity for fiber-based, Gigabit Ethernet LANs.
Gigabyte
1 interface (mini-GBIC)—This card supports 1 fiber interface and uses an optical cable
with SX or LX connectors.
2 interfaces (GBIC)—This card supports 2 fiber interfaces and uses an optical cable
with SX or LX connectors.
Gigabyte LX/SX (2 interfaces)—This card supports 2 fiber interfaces and uses an optical
cable with SX and LX connectors.
Secure Port Modules (SPMs) provide general packet processing and device connection
tasks for the NetScreen 5000 line. These modules are based on either the GigaScreen-II
or Jupiter-II ASIC.
SPMs handle packets as they enter and exit the system, providing packet parsing,
classification, and flow-level processing. SPMs also provide encryption, decryption,
