A2H254-16; Overview - Enterasys SecureStack A2 A2H254-16 Hardware Installation Manual

Overview

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.
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 (Figure 1‐1) 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
–
–
• 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.
• Rear panel Redundant Power Supply connector for a redundant power supply
connection. The switch connects to an Enterasys C2RPS‐SYS using a C2RPS‐PSM
Cable.

optional Mini‐GBIC 1000BASE‐T Ethernet over copper RJ45 connections for 1000
Mbps operation
optional 1000BASE‐SX/LX/ELX fiber‐optic connections
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.
Precaución: El dispositivo A2H254-16 no cumple con el estándar PoE. No conecte una
fuente de poder redundante (RPS) SecureStack C2 PoE (C2RPS-POE) al cable de
corriente directa. De lo contrario, el dispositivo puede dañarse.
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).
