Enterasys Networks A2H254-16 ユーザーズマニュアル
Overview
1-2 Introduction
The switch also supports the use of a redundant DC power supply to help prevent
downtime due to an internal power supply failure in the switch or AC power source.
downtime due to an internal power supply failure in the switch or AC power source.
You can install the SecureStack A2
on a flat surface or into a standard 19‐inch rack with
user‐supplied mounting hardware, and configure the SecureStack A2 functions using the
WebView™ application, CLI switching commands, and/or SNMP.

A2H254-16
The A2H254‐16 (
) has several types of front panel ports and rear panel
connections, which include:
•
Eight 100BASE‐T 10/100 Mbps copper RJ45 ports (odd numbered 1‐15)
•
Eight 100BASE‐FX multimode MT‐RJ ports (even numbered 2‐16)
•
Two SFP slots labeled port 19 and 20 that support
–
optional Mini‐GBIC 1000BASE‐T Ethernet over copper RJ45 connections for 1000
Mbps operation
Mbps operation
–
optional 1000BASE‐SX/LX/ELX fiber‐optic connections
•
Two 1000BASE‐T RJ45 ports labeled 17 and 18 which can be used in a stack
configuration as well as standard Gigabit Ethernet switch ports when configured as a
standalone switch.

Caution: The A2H254-16 is not a PoE-compliant device. Do not connect a SecureStack
C2 PoE Redundant Power System (C2RPS-POE) to the power connector. Otherwise,
damage to the device may result.

Note: The 1000BASE-T built-in RJ45 stacking ports 17 and 18 on the A2H254-16 can be
configured as standard 10/100/1000BASE-T switch ports, using the command “set switch
stackport <ethernet | stack>” when the unit is in standalone mode (not stacked).
